as a tire and alignment guy for the past 25 yrs, I can appreciate all the upgrades in tire engineering and equipment to install them.....i have worked on Coats machines in the early 80s to Hunter machines of today and a lot of the technology has to do with TPMS, alloy and aluminum rims and very stiff and short sidewalls of tires...these weren't big issues in the 80s and 90s for mass tire installations...but as cars got lighter and materials weren't steel anymore, the equipment had to change with the designs...as a big truck alignment mechanic, I saw the differences in a 250 dollar tire and a 400 dollar Michelin and YES, there is a difference...the same goes with car tires and cheaper tires, you get what you pay for a lot of the times.....a video on worn tire testing would be a great idea because all new tires perform pretty well...it's the ones that are half worn and can't drive through a small puddle of water or a wet highway that are the ones to be concerned about...great video and i think you are just scratching the surface on what you can make videos about...thanks

The randomizing of the tread pattern is a principle that was also used on the highway system. Expansion joints in the road were once equally spaced giving the tire noise a similar effect we often associate with railroad tracks. It was found that this can have an effect on car drivers which would tend to make them drowsy or even put them to sleep. Nowadays, there are 3 or 4 standard spacings, randomly installed to minimize this problem.
Long ago, on a long highway trip, we drove by a car on a concrete highway with regularly spaced expansion strips. The two guys in the car were doing an exaggerated "bounce" in their car seats every time they hit an expansion strip. It gave us a good chuckle.
I never knew about those round of corners in the socket wrench and the frequency distribution of the tire noise. Super interesting! For many everyday objects you never really stop and appreciate the design and engineering and just overal cleverness that went into it. Hope to see many more of these kind of videos!
If you take a look at "metrinch" sockets and wrenches, they over exaggerate this awesome tool trick. My uncle thought they were awesome but came to realize that they fit kinda loose on the nut or bolt.... Not good
Awesome video Andrew, and well done on the re-branding. I've been a sub of the dash cam reviews for years but these documentaries are fascinating! Would love a video on how useful the new safety features are in cars these days. Seems like manufacturers are adding more and more - lane keep assist, adaptive speed cruise control, safe exit assist etc etc
This feels extremely professional, it’s clear you took everything you’ve learned over the years and tailored it into a much more broader reaching category of topic. It works perfectly! Absolutely love it, definitely earned a subscriber!
Yeah people don't realize most roads were dirt or gravel and then have gradually been replaced with paved roads. Our Farm to Market road in front of the farm was a dirt road until the late 1950's... Grandma told me she used to be able to drive the Model A Ford onto the road, your tires fell into the muddy ruts, and the car would steer itself all the way to town 5 miles away, following the ruts! OL J R :)
I was an early adherent of radial tires, having Semperit Supersports on my 1962 VW Beetle in the mid 1960s. Because of this or that I had the fronts mounted a week or two before the rears. The difference in those weeks was incredible. After all four were installed the difference was phenomenal. I never went back. If you ever drove a Beetle, you know how wiggley its read end was.
I went from bias-ply to radials in 1977. The difference was astonishing. If I had to drive on those old tires today, I'd be terrified. I can think of times I came close to dying, when I would have been perfectly safe on better tires. For some reason, I still buy the cheapest tires I can find, though. Maybe it's time to re-think that.
Bias ply tires still have their place, though... they're particularly good for trailer tires, as radials just don't hold up. I've had bias ply tires running just fine on a cattle trailer for over 20 years-- only reason I had to replace them was the rubber dried out and the tread layer peeled off, even then I drove the last 20 miles to an auction barn on the exposed strings of the plies LOL:) I wanted another set of biases but the tire shop didn't have any so I had to get some of the "new, improved" Goodyear radial trailer tires. I'd heard that radials were lousy trailer tires but the dealer insisted they were fine, just keep them aired up to 60 PSI when parking the trailer between uses so they didn't develop "flat spots" that weaken the plies. Well, they lasted about four years and blew out hauling a load of calves. Had maybe 600-800 miles on the tires. I went back to biases and no problems. I will ONLY buy bias trailer tires from now on. OL J R :)
I remember when I was a kid, once I had used a mix of radial and bias-ply tires due to economics (I was poor). With that mix of tire types, my car (1964 Dodge Polara) was almost impossible to control! It scared the daylights out of me to even drive it at 40MPH. Having clearly seen the issues of mixing tire types, I never did that again. So thankful when radials became the norm and bias-ply tires disappeared from passenger cars altogether. The engineering that goes into tires is amazing!
@@rachelblack3816 Yeah mixing biases and radials was a big no-no, particularly radials on the front and biases on the back, IIRC (could have been the other way around, too many years ago to remember exactly). Basically the sidewalls flex different in turns which creates "understeer" or "oversteer" going around curves, or as the weight of the vehicle shifts with slight steering corrections, which amplifies the motion. Radials are good for some things, and not so good for others. For trailers IMHO biases are still FAR superior in longevity and weight-carrying ability, at least for smaller trailers. Later! OL J R : )
@@lukestrawwalker I had always wondered why trailer tires, and from their appearances large truck tires as well, were still bias-ply. I guess that explains why! Thank you.
After your last video, I subbed. That is the stuff like to see, explanations of everyday things that I would have overlooked otherwise. This video was in line with that. Thank you for educating me, will make my next tire shopping a more informed one.
Hello! I'm not much of a dashcam user so the new direction of your channel is something that drew me in. this one and the video about the crash barriers are really interesting, to the point and I think you are a good presenter. Basically very high quality content that is hard to find new sources of nowadays. I'm looking forward to more!
Great videos! You're really hitting your stride with this new style and format. I'm gonna miss your dashcam reviews given you did such a great job with them over the years, but I'm also very happy to see you continuing to do what's most fun and exciting for you!
This is the first video I've seen of yours and it's excellent! It's easy to ignore the small details in the engineering of products which make a huge difference in performance. Your discussion about the design and implementation of siping brings to light one of the many seemingly minute differences which make a big difference in performance and, by extension, safety. Consumers should be aware of compromises made in designs balancing cost and performance. Thanks for the great video. Keep up the good work!
It's amazing that the equipment to change tires evolved as well. When you consider the overall technology involved in the building and improvement of modern motor vehicles including EVs in the span of just 50 years it's very impressive.
I had two consecutive vehicles that used the same tire size. I was also putting a lot of miles on my vehicles over the time when I owned said two vehicles. Consequently, I bought “several” sets of tires. What I found was that some of the highest priced tires actually ended up being the least expensive because of their practical longevity. They were also the nicer driving/riding/performing tires right from new.
@@PublishX Damn dude, you're on top of your comment game. Really appreciate the kind words. I was worried at the beginning as I'm basically waiting on the RUclips gods to deliver me views. I spent a week after launch tweaking the thumbnail. I'm sure you know that game well. I'm impressed with your speed of production and quality. I've added a few of your videos to my playlist. Going to be my lunchtime viewing today.
Showed up in my recommended, I have to appreciate the level of detail you put in to the research of tires and such. I work as a car mechanic since graduation (5 years) and while we still use regular tire machines which assist of removing the tire with your manual input, and of course alignment work being done, I appreciate the understanding you have for the profession. I work at a car dealership but we have a lot of contacts with motorsports so we do a lot of specific alignments and tuning work depending on the season. Subscribed to see more from you, and see if you follow through on these things that the normal consumer might not know about :)
I drove a Volvo S60 a couple of years ago and I was surprised by two things: 1) How well the adaptive cruise control and lane assist worked, and 2) how absolutely unbelievably lousy it was about letting you know that it was no longer in action (like, when a lane split and the car no longer knew what was what). These new technologies definitely need some in-depth reviews. Thanks for the info on tires! I'm less inclined to buy cheap tires, that's for sure!
You can just tell how much thought and planning has gone into this video before he even touches a camera. Really high quality stuff, I cant wait to see more!
Great content Andrew! I just watched the crash barrier video before this one and both were informative, interesting and cool too! I look forward to future videos!
Cool video. I'm definitely in the "you get what you pay for" camp when it comes to tires. More expensive brand name tires may hurt more now but they can literally save your life when it comes to handling and braking performance.
Yeah sure... remember those Goodyear tires that were tossing their tread and killing people driving Ford Explorers?? My '92 F-150 came with Goodyear Wranglers from the factory, I was like "wow that's the best set of tires I've EVER seen on a new vehicle!" as all our previous trucks had the sh!ttiest tires Ford could get on them from the factory. Well, the stupid Goodyears must've been made out of old eraser rubber... those things were SLICK BALD at 25,000 miles! I usually keep old tires to use on farm trailers and implements where tread doesn't matter, but these were SO slick that I couldn't even use them for that! GARBAGE! Best tires I've ever run were the Continental Conti-tracks. Ran those on my pickup for years, until I couldn't get them anymore because they stopped carrying them. They were a 60,000 mile tire and they'd run every inch of it before they needed replaced. Since then I've just been running the cheapest tires I can get, because I've never had a set of Goodyears or Firestones be actually worth what they were charging for them. They'd either wear out or fail long in many cases before reaching even a paltry 30,000 mile wear. Later! OL J R :)
I couldn't help noticing the cute squirrel 🐿on the top right corner of the video jumping on the roof at 8:04 . Oh... and nice tire engineering lesson, by the way. 🤣
Awesome video. I work in collision repair and I can honestly say I've seen literally hundreds of cars come into my shop and the customer says they don't know what happened but they pressed the brake and they lost control under damp or wet conditions. And 99% of the time they had cheap tires w plenty of tread but the sipes were completely smooth. A large number were also the cause of blowed tires where defects in the tire were at fault.
Really glad to see this channel blowing up. Your interest in engineering is so apparent. I would love to see a BREAKdown of automotive braking systems from conception
I watched your dash cam vids and absolutely loved them! This video was really good and I can't wait to see more like them! Your energy, passion, and enthusiasm is what I am here for! Keep it up!
Another great video with lots of valuable information. It kept me engaged from start to finish. The Tire spreader that looks like some kind of Spanish Inquisition torture device for tires can still be found in many tire shops today. It makes it easier to inspect and repair damaged tires. This is very useful for tires with a tall sidewall. When you patch a tire you have to slightly grind the inner surface of the tire so the patch can properly adhere. Low-profile tires are easier to inspect & repair but are much more difficult to install and remove. With the old tire machines, it was very easy to damage a low-profile tire when trying to break the bead from the rim. This is because there's almost zero flexibility in the sidewall of a low-profile tire. I might be wrong, but I was thinking that car and driver magazine did a test of a few tire brands to see how well they lasted over their lifetime. In any case, it's your attention to detail that has brought this issue to the forefront. Great job and I look forward to seeing your next video!
Great stuff Andrew! I think a good starting point, to hold tire companies to a higher safety standard, is to keep a running list of brands to avoid because they use the engineering cheat.
it's not a cheat, its a tradeoff. if the sipes go all the way to the bottom of every tread block , the block loses rigidy and will bend and twist causing a squirmmy feel as you drive and it will create more heat in the rubber making it wear even faster
Congrats on moving your channel in a new direction! I bet it isn’t easy to break with 7 years knowledge. I just found your channel but I immediately subbed when you told what your future videos are going to be about.. The thought, engineering and development that goes into things that you never really think about is incredibly interesting.
It‘s important to note that the geometry of the tread is only scratching the surface, no pun intended. The tread for example is made of different rubber compounds that have different properties.
This video seems to have been blessed by the algorithm. Loved the information and crash-test footage! I'd like to see more of this and hope you enjoy making videos like this 👍
glad to hear the content shift, deep dives into seemingly mundane topics are some of my favourite content on this website, the world becomes so much more interesting when you learn how much there is to learn about anything and everything.
After my first time driving on high end sport tires, I realized tires can completely change how a far feels and performs. I have so much appreciation for tires now, would never skimp on them
I’m impressed with the amount of engineering that’s gone into tires since I started driving 20 years ago. I drive huge pick up trucks. The latest set of tires, ultimate all weather performance, and a ride smooth as a Cadillac. You become a tire nut when you have to buy truck tires, trust me. People with cars don’t feel this pain normally, and a blown tire isn’t all that bad. On a truck, for a trustworthy tire (something you need when rolling with 3 tons pulling 5 tons) you’re not getting out of it less than $300 a tire before mounting.
motorcyclists are similar, but for different reasons. for us its less the cost and more the fact that a ditchfinder is death rather than injury. us bikers will argue PASSIONATELY about the "best" tyres. for me, I swear by road 5's for my fazer and city pro's for my cbf.
at 10:02 the antique tire spreader. I used to use something similar to that back in 2014, its used to open up the inside for inspection and repair. basically plug holes from nails or whatnot. you would use a dremel with rough grit to clear the area then plug, patch, and glue so it becomes safe to reinflate.
I know the principle described after 3:20 from electronics. In digital electronics they sometimes deliberatly jitter the clock frequency to spred out the EMI (electromagnetic noise output) of a product. Works just like that, exept in the radio spectrum. Absolutely incredible that they also use that in mechanics, never thought about that!
Great video. You should do one on those absurdly bright LED headlights next (and headlights in general), those things are a danger to everyone on the road.
I just found you, but I love your videos! These are honestly the coolest things I've seen. As a person with a design degree, I love seeing all sorts of engineering things I didn't think of! thank you!
Just a thought: When you temporarily go off on a tangent to prove a point, it can be slightly confusing to figure out if the entire topic changed. What about an watermark in the corner of you and a bear (bear-with-me) during these point-makers?
I really appreciate the feedback. I'm guessing that's regarding the car crash section? I think I might do that or another method to help indicate that this isn't exactly on topic but it has a point I want to make
@@Lam Joe Scott (Answers With Joe) has a "tangent cam" he uses when talking about things like that. Great video BTW! I loved your last one and was surprised to find out it wasn't something you did regularly, glad to hear you're going to be focusing on it.
Some people actually do that. Not particularly _smart_ people, mind you, but they'll trick themselves into refusing to pay for new tires on their $100,000 car, and just bail
I used to work with one of those things at 10:02 it's used to create a wide flat surface to work on when patching leaks with the application of a rubber patch to the interior of the tire with vulcanizing cement. Haven't seen one in ages, and the one I worked with was already ancient long ago.
06:20 ... dang, you make me feel old. When I was in high school I worked for a nationwide tire company. We sold bias ply and radial tires and we used the COATS 40-40 tire changing machine. Back then, a "large" wheel was the 16.5" and were in both solid wheel or split rim (split ring) wheels. Passenger car tires were from 10" to 15" and special order tires could go up to 17". We had no method to mount any tire larger than a 17" tire and a sidewall of 55 was the lowest profile the machines (and technicians) could mount. Still, I remember asking customers who wanted radial tires if their cars had "radial-tuned suspension" because if the car was designed to use bias ply tires and you mounted a steel-belt radial tire onto the car, the car would drift side to side like it had really bad alignment problems, but instead of being pulled to one side, the car would pull both directions and therefore the drivers could not exceed certain speeds without losing control of the vehicle... think about riding a skateboard going downhill. The faster and faster you go, the more wobble in the board at the trucks and you eventually lose control. That is what would happen if your car was not tuned at the factory to use radial tires when it was made. Most carmakers would "brag" about their new designs by putting a decal or emblem on the side of the car above the wheel well saying "Radial Tuned Suspension" or just "Radial Tuned". That tuning was a great selling point for car dealerships because the buyer would know they could safely use the more gas-saving radial tires. There are benefits to "glass tires" as the bias ply were known... they could handle heavier loads without suffering sidewall separation, but were mostly used on commercial vehicles or heavy-load personal pickup trucks that wouldn't be driving fast with a load in the bed anyway. Although I eventually became an engineer in the sheet metal and steel industry, I do miss the days of working in the old tire shops of the 70s and early 80s. There were no fancy tire changing machines, we jacked up vehicles with floor jacks, not lifts that are ubiquitous today. I mean you only need to get a vehicle a few inches off the ground to change the tires anyway. Sure, we worked on our knees or strained our backs bending over to work, but the speed we could change all four tires on a car with two technicians was literally five minutes... that's from the moment the car drove into the bay, jack up, pulle the hubcaps, remove lug nuts and wheel, change the tire, balance it on a spin balancer, mount the tires/wheels back on the car, tighten the lug nuts, lower the jacks and torque spec the lug nuts, then replace the hubcaps. Two technicians on a car... five minutes and it's ready to drive out of the shop... and we didn't need to run to the cars like a certain tire chain makes their techs do for each customer. I miss those days of hard work.
10:02 I’m a tire guy, that is used to hold the tire in place and open it up, usually for patching nails and other punctures. The shop I work at still uses them (although ours is much more compact), it’d take at least twice as long without i
I have been looking for this information for quite a while. I am surprised you did not mention tire age. Tires have a manufacture date on them as unused tires break down after several years. Great video.
10:02 someone else probably already said it, but this is to spread the tire open to install a plug when the tire gets punctured. Allows the tech to fit a grinder in to rough up the surface so glue can stick better.
Great vid. The thing about making the car crash tests harder is it makes it harder to pass, making it harder to produce, making the end product much more expensive. We should always ask about an improvement to make something better is, "At what cost". Sometimes it is not worth it to have to pay $80,000.00 for a truck. Or $25,000.00 for a modest car. Sometimes it is not worth it to have to take the time for technology to reach the expectations for the improvement to be implemented. Sometimes it is worth it to not to have to pay or wait for it... At least give us the option.
This was a very fun video for me. I started changing tires in 2003 and the tire industry has come a LOOONG way in regards to servicing tires and wheels. It’s simpler yet more complicated than ever. There are more tools available to help change tires but the cost for this precision equipment is extremely high and all require quite a bit of hands on experience to use efficiently without sacrificing quality or damaging your tools.
Not an engineer, but the ingenuity blows me away every single time. From Machining to Coke Cans, I'm honestly shocked the human mind has the capacity for such elegant solutions. God Bless.

Thanks impact! That's exactly what I thought when I first saw that! Glad I was able to convey both those concepts to you.
Also, if you look at older fan blades on cars, the blades from one to another are different sizes.
If you take a look at "metrinch" sockets and wrenches, they over exaggerate this awesome tool trick.
My uncle thought they were awesome but came to realize that they fit kinda loose on the nut or bolt.... Not good
Awesome video Andrew, and well done on the re-branding. I've been a sub of the dash cam reviews for years but these documentaries are fascinating!
Would love a video on how useful the new safety features are in cars these days. Seems like manufacturers are adding more and more - lane keep assist, adaptive speed cruise control, safe exit assist etc etc
Hey Hughesy, thanks for the suggestion. They are definitely add a ton more features. Appreciate the support.
Well done. BTW, I got here from Digg, so the Internet is definitely noticing.
@DeathNikki Well, it isn't what it was a decade or so ago.
This feels extremely professional, it’s clear you took everything you’ve learned over the years and tailored it into a much more broader reaching category of topic. It works perfectly!
Absolutely love it, definitely earned a subscriber!
Thanks Jagger! Really appreciate the compliment. I'll keep doing my best
the "vintage" tread worked well on dirt (more fitting for the time)
and is still used on knobbies
Yeah people don't realize most roads were dirt or gravel and then have gradually been replaced with paved roads. Our Farm to Market road in front of the farm was a dirt road until the late 1950's... Grandma told me she used to be able to drive the Model A Ford onto the road, your tires fell into the muddy ruts, and the car would steer itself all the way to town 5 miles away, following the ruts! OL J R :)
Yes and this is also why knobbies are loud af haha
I was an early adherent of radial tires, having Semperit Supersports on my 1962 VW Beetle in the mid 1960s. Because of this or that I had the fronts mounted a week or two before the rears. The difference in those weeks was incredible. After all four were installed the difference was phenomenal. I never went back. If you ever drove a Beetle, you know how wiggley its read end was.
I went from bias-ply to radials in 1977. The difference was astonishing. If I had to drive on those old tires today, I'd be terrified. I can think of times I came close to dying, when I would have been perfectly safe on better tires. For some reason, I still buy the cheapest tires I can find, though. Maybe it's time to re-think that.
Bias ply tires still have their place, though... they're particularly good for trailer tires, as radials just don't hold up. I've had bias ply tires running just fine on a cattle trailer for over 20 years-- only reason I had to replace them was the rubber dried out and the tread layer peeled off, even then I drove the last 20 miles to an auction barn on the exposed strings of the plies LOL:) I wanted another set of biases but the tire shop didn't have any so I had to get some of the "new, improved" Goodyear radial trailer tires. I'd heard that radials were lousy trailer tires but the dealer insisted they were fine, just keep them aired up to 60 PSI when parking the trailer between uses so they didn't develop "flat spots" that weaken the plies. Well, they lasted about four years and blew out hauling a load of calves. Had maybe 600-800 miles on the tires. I went back to biases and no problems. I will ONLY buy bias trailer tires from now on. OL J R :)
I remember when I was a kid, once I had used a mix of radial and bias-ply tires due to economics (I was poor). With that mix of tire types, my car (1964 Dodge Polara) was almost impossible to control! It scared the daylights out of me to even drive it at 40MPH. Having clearly seen the issues of mixing tire types, I never did that again. So thankful when radials became the norm and bias-ply tires disappeared from passenger cars altogether. The engineering that goes into tires is amazing!
@@rachelblack3816 Yeah mixing biases and radials was a big no-no, particularly radials on the front and biases on the back, IIRC (could have been the other way around, too many years ago to remember exactly). Basically the sidewalls flex different in turns which creates "understeer" or "oversteer" going around curves, or as the weight of the vehicle shifts with slight steering corrections, which amplifies the motion. Radials are good for some things, and not so good for others. For trailers IMHO biases are still FAR superior in longevity and weight-carrying ability, at least for smaller trailers. Later! OL J R : )
@@lukestrawwalker I had always wondered why trailer tires, and from their appearances large truck tires as well, were still bias-ply. I guess that explains why! Thank you.
After your last video, I subbed. That is the stuff like to see, explanations of everyday things that I would have overlooked otherwise. This video was in line with that. Thank you for educating me, will make my next tire shopping a more informed one.
Hello!
I'm not much of a dashcam user so the new direction of your channel is something that drew me in. this one and the video about the crash barriers are really interesting, to the point and I think you are a good presenter. Basically very high quality content that is hard to find new sources of nowadays. I'm looking forward to more!
The "Tire Spreader" is used in tire repair, making installing a patch to a puncture much easier. Great video!
Great videos! You're really hitting your stride with this new style and format. I'm gonna miss your dashcam reviews given you did such a great job with them over the years, but I'm also very happy to see you continuing to do what's most fun and exciting for you!
As an engineer, This is really interesting to learn what goes behind making everyday objects perform better. Nice video!
This is the first video I've seen of yours and it's excellent! It's easy to ignore the small details in the engineering of products which make a huge difference in performance. Your discussion about the design and implementation of siping brings to light one of the many seemingly minute differences which make a big difference in performance and, by extension, safety. Consumers should be aware of compromises made in designs balancing cost and performance. Thanks for the great video. Keep up the good work!
It's amazing that the equipment to change tires evolved as well. When you consider the overall technology involved in the building and improvement of modern motor vehicles including EVs in the span of just 50 years it's very impressive.
I had two consecutive vehicles that used the same tire size. I was also putting a lot of miles on my vehicles over the time when I owned said two vehicles. Consequently, I bought “several” sets of tires. What I found was that some of the highest priced tires actually ended up being the least expensive because of their practical longevity. They were also the nicer driving/riding/performing tires right from new.
I am so proud of this community making the most replayed part the video the end of the ad.
glad to see a new video from you!!
Thanks! Really appreciate the support including your comments on the last video too.
@@Lam yes bro and looks like this video is blowing up right now! Grats and keep these coming
@@PublishX Damn dude, you're on top of your comment game. Really appreciate the kind words. I was worried at the beginning as I'm basically waiting on the RUclips gods to deliver me views. I spent a week after launch tweaking the thumbnail. I'm sure you know that game well.
I'm impressed with your speed of production and quality. I've added a few of your videos to my playlist. Going to be my lunchtime viewing today.
Showed up in my recommended, I have to appreciate the level of detail you put in to the research of tires and such. I work as a car mechanic since graduation (5 years) and while we still use regular tire machines which assist of removing the tire with your manual input, and of course alignment work being done, I appreciate the understanding you have for the profession. I work at a car dealership but we have a lot of contacts with motorsports so we do a lot of specific alignments and tuning work depending on the season.
Subscribed to see more from you, and see if you follow through on these things that the normal consumer might not know about :)
I drove a Volvo S60 a couple of years ago and I was surprised by two things: 1) How well the adaptive cruise control and lane assist worked, and 2) how absolutely unbelievably lousy it was about letting you know that it was no longer in action (like, when a lane split and the car no longer knew what was what). These new technologies definitely need some in-depth reviews. Thanks for the info on tires! I'm less inclined to buy cheap tires, that's for sure!
Glad to hear you'll be making more videos like this! Here's some big $$$ to help you on your journey.
Much appreciated! Thanks a bunch!
You can just tell how much thought and planning has gone into this video before he even touches a camera. Really high quality stuff, I cant wait to see more!
Thanks!
Great content Andrew! I just watched the crash barrier video before this one and both were informative, interesting and cool too! I look forward to future videos!
Cool video. I'm definitely in the "you get what you pay for" camp when it comes to tires. More expensive brand name tires may hurt more now but they can literally save your life when it comes to handling and braking performance.
And thats not true many cheaper tires brand are own by bigger brands and have same specs but only key difrance is price and logo
No it is true budget tyres suck, need at least mid range or upper mid range tyres to have good tyre performance and safety.
Yeah sure... remember those Goodyear tires that were tossing their tread and killing people driving Ford Explorers?? My '92 F-150 came with Goodyear Wranglers from the factory, I was like "wow that's the best set of tires I've EVER seen on a new vehicle!" as all our previous trucks had the sh!ttiest tires Ford could get on them from the factory. Well, the stupid Goodyears must've been made out of old eraser rubber... those things were SLICK BALD at 25,000 miles! I usually keep old tires to use on farm trailers and implements where tread doesn't matter, but these were SO slick that I couldn't even use them for that! GARBAGE!
Best tires I've ever run were the Continental Conti-tracks. Ran those on my pickup for years, until I couldn't get them anymore because they stopped carrying them. They were a 60,000 mile tire and they'd run every inch of it before they needed replaced. Since then I've just been running the cheapest tires I can get, because I've never had a set of Goodyears or Firestones be actually worth what they were charging for them. They'd either wear out or fail long in many cases before reaching even a paltry 30,000 mile wear. Later! OL J R :)
I couldn't help noticing the cute squirrel 🐿on the top right corner of the video jumping on the roof at 8:04 . Oh... and nice tire engineering lesson, by the way. 🤣
Engineer here from Germany - amazing work! Especially the part regarding the noise engineering!
I always thought of how tire designs were made and why. It's just fascinating to hear how they evolved in every day use.
Awesome video. I work in collision repair and I can honestly say I've seen literally hundreds of cars come into my shop and the customer says they don't know what happened but they pressed the brake and they lost control under damp or wet conditions. And 99% of the time they had cheap tires w plenty of tread but the sipes were completely smooth. A large number were also the cause of blowed tires where defects in the tire were at fault.
honest question; how can tires be so worn out before someone at the inspection catches this?
Wow, a _revolution_ in tire making machines
What a nice informative video with good visualizations! This channel will be 1M+ in short time. Thanks for the video!
Really glad to see this channel blowing up. Your interest in engineering is so apparent. I would love to see a BREAKdown of automotive braking systems from conception
I watched your dash cam vids and absolutely loved them! This video was really good and I can't wait to see more like them! Your energy, passion, and enthusiasm is what I am here for! Keep it up!
Another great video with lots of valuable information. It kept me engaged from start to finish. The Tire spreader that looks like some kind of Spanish Inquisition torture device for tires can still be found in many tire shops today. It makes it easier to inspect and repair damaged tires. This is very useful for tires with a tall sidewall. When you patch a tire you have to slightly grind the inner surface of the tire so the patch can properly adhere. Low-profile tires are easier to inspect & repair but are much more difficult to install and remove. With the old tire machines, it was very easy to damage a low-profile tire when trying to break the bead from the rim. This is because there's almost zero flexibility in the sidewall of a low-profile tire. I might be wrong, but I was thinking that car and driver magazine did a test of a few tire brands to see how well they lasted over their lifetime. In any case, it's your attention to detail that has brought this issue to the forefront. Great job and I look forward to seeing your next video!
Very informational, gonna show the kids at my local high school auto shop next time I drop over there
Thanks John!
this is the first vid of yours i watched andrew, nice clear concise narration, interesting topic, look forward to more.
Holy smokes the editing for this is flipping amazing, and I love how frenetic the energy in the lil animations are
Great stuff Andrew! I think a good starting point, to hold tire companies to a higher safety standard, is to keep a running list of brands to avoid because they use the engineering cheat.
it's not a cheat, its a tradeoff. if the sipes go all the way to the bottom of every tread block , the block loses rigidy and will bend and twist causing a squirmmy feel as you drive and it will create more heat in the rubber making it wear even faster
Congrats on moving your channel in a new direction! I bet it isn’t easy to break with 7 years knowledge. I just found your channel but I immediately subbed when you told what your future videos are going to be about.. The thought, engineering and development that goes into things that you never really think about is incredibly interesting.
It‘s important to note that the geometry of the tread is only scratching the surface, no pun intended. The tread for example is made of different rubber compounds that have different properties.
This video seems to have been blessed by the algorithm. Loved the information and crash-test footage! I'd like to see more of this and hope you enjoy making videos like this 👍
glad to hear the content shift, deep dives into seemingly mundane topics are some of my favourite content on this website, the world becomes so much more interesting when you learn how much there is to learn about anything and everything.
After my first time driving on high end sport tires, I realized tires can completely change how a far feels and performs. I have so much appreciation for tires now, would never skimp on them
8:00 "This should change, and --SQUIRREL!"
I’m impressed with the amount of engineering that’s gone into tires since I started driving 20 years ago.
I drive huge pick up trucks. The latest set of tires, ultimate all weather performance, and a ride smooth as a Cadillac.
You become a tire nut when you have to buy truck tires, trust me. People with cars don’t feel this pain normally, and a blown tire isn’t all that bad.
On a truck, for a trustworthy tire (something you need when rolling with 3 tons pulling 5 tons) you’re not getting out of it less than $300 a tire before mounting.
motorcyclists are similar, but for different reasons. for us its less the cost and more the fact that a ditchfinder is death rather than injury.
us bikers will argue PASSIONATELY about the "best" tyres.
for me, I swear by road 5's for my fazer and city pro's for my cbf.
at 10:02 the antique tire spreader. I used to use something similar to that back in 2014, its used to open up the inside for inspection and repair. basically plug holes from nails or whatnot. you would use a dremel with rough grit to clear the area then plug, patch, and glue so it becomes safe to reinflate.
Great content and delivered in a format anyone can enjoy.
Amazing explanation video as always!!
How would you know. it's only been out for 2 minutes, and it's a 12 minute video
@@modernkennnern I am watching it
Glad you liked it 😉
Andrew the man is back with a deep dive I didn't know I wanted to dive into. Love the new style of videos and looking forward to seeing more !
Thanks Lewis! Appreciate the support!
Yes absoloutly more of this pls!
10:00 tire spreader, handy for patching the inside of the tire. We had a simple manual one when I worked at a service station back in the 1970s.
I know the principle described after 3:20 from electronics. In digital electronics they sometimes deliberatly jitter the clock frequency to spred out the EMI (electromagnetic noise output) of a product. Works just like that, exept in the radio spectrum. Absolutely incredible that they also use that in mechanics, never thought about that!
Great video. You should do one on those absurdly bright LED headlights next (and headlights in general), those things are a danger to everyone on the road.
Especially retro fitted to older cars, not always particularly suited to them
Great video!
woo Jessassin!
Thanks!
I loved the road barrier video, and this one was excellent as well! I look forward to the new direction your channel is headed in
This was amazing and great editing too! Great pacing and very informative! Keep it up
I just found you, but I love your videos! These are honestly the coolest things I've seen. As a person with a design degree, I love seeing all sorts of engineering things I didn't think of! thank you!
Thanks a bunch!
I am honestly disappointed that after saying "wait a minute" the sponsorship part didn't last exactly 1 minute lol
0:03 is he ... the Iron man?
Great video. Loved the topics, and very interesting
Love the new direction and I am looking forward to more videos showing of the hidden thought processes and engineering of things we take for granted!
Just a thought: When you temporarily go off on a tangent to prove a point, it can be slightly confusing to figure out if the entire topic changed. What about an watermark in the corner of you and a bear (bear-with-me) during these point-makers?
I really appreciate the feedback. I'm guessing that's regarding the car crash section? I think I might do that or another method to help indicate that this isn't exactly on topic but it has a point I want to make
@@Lam Joe Scott (Answers With Joe) has a "tangent cam" he uses when talking about things like that. Great video BTW! I loved your last one and was surprised to find out it wasn't something you did regularly, glad to hear you're going to be focusing on it.
Though I think creative use of chapters is acceptable instead, I can't see how such a thing would hurt.
Really, really well done production, along with being far more interesting than I expected. Great job!
rename channel name? congrats!
Yup! Channel renamed. Thanks Budiono
What did it used to be called?
@@ashr “Andrew Lam’s Femboy Review Channel”
@@nana-booboostickyourheadin4169 a truly epic name
this is a brilliant idea for a channel, this is the first video of yours that I've seen and you completely got me.
8:03 squirrel at the back :)
It seems to be a simple object but there's a lot and engineering and R&D behind it. Thanks for this amazing video.
0:20 The Apple of tire machines? You mean, when your tire's too flat, you gotta go back to the dealer and buy a brand new car?
Some people actually do that. Not particularly _smart_ people, mind you, but they'll trick themselves into refusing to pay for new tires on their $100,000 car, and just bail
You found the apple of tire machines? That means everything is overpriced, hard to repair yourself and you have to buy your own power cable?
may be just a subjective review from me, but we have 2 machines and the older one is definitely better😭and easier to handle
I used to work with one of those things at 10:02 it's used to create a wide flat surface to work on when patching leaks with the application of a rubber patch to the interior of the tire with vulcanizing cement. Haven't seen one in ages, and the one I worked with was already ancient long ago.
Thank you for producing this video and sharing it on RUclips.
Did you see the squirrel? 🐿️
First video I’ve watched for this channel and subbed straight away. Such great and interesting content and all explained so well
06:20 ... dang, you make me feel old. When I was in high school I worked for a nationwide tire company. We sold bias ply and radial tires and we used the COATS 40-40 tire changing machine. Back then, a "large" wheel was the 16.5" and were in both solid wheel or split rim (split ring) wheels. Passenger car tires were from 10" to 15" and special order tires could go up to 17". We had no method to mount any tire larger than a 17" tire and a sidewall of 55 was the lowest profile the machines (and technicians) could mount.
Still, I remember asking customers who wanted radial tires if their cars had "radial-tuned suspension" because if the car was designed to use bias ply tires and you mounted a steel-belt radial tire onto the car, the car would drift side to side like it had really bad alignment problems, but instead of being pulled to one side, the car would pull both directions and therefore the drivers could not exceed certain speeds without losing control of the vehicle... think about riding a skateboard going downhill. The faster and faster you go, the more wobble in the board at the trucks and you eventually lose control.
That is what would happen if your car was not tuned at the factory to use radial tires when it was made. Most carmakers would "brag" about their new designs by putting a decal or emblem on the side of the car above the wheel well saying "Radial Tuned Suspension" or just "Radial Tuned". That tuning was a great selling point for car dealerships because the buyer would know they could safely use the more gas-saving radial tires.
There are benefits to "glass tires" as the bias ply were known... they could handle heavier loads without suffering sidewall separation, but were mostly used on commercial vehicles or heavy-load personal pickup trucks that wouldn't be driving fast with a load in the bed anyway.
Although I eventually became an engineer in the sheet metal and steel industry, I do miss the days of working in the old tire shops of the 70s and early 80s. There were no fancy tire changing machines, we jacked up vehicles with floor jacks, not lifts that are ubiquitous today.
I mean you only need to get a vehicle a few inches off the ground to change the tires anyway. Sure, we worked on our knees or strained our backs bending over to work, but the speed we could change all four tires on a car with two technicians was literally five minutes... that's from the moment the car drove into the bay, jack up, pulle the hubcaps, remove lug nuts and wheel, change the tire, balance it on a spin balancer, mount the tires/wheels back on the car, tighten the lug nuts, lower the jacks and torque spec the lug nuts, then replace the hubcaps.
Two technicians on a car... five minutes and it's ready to drive out of the shop... and we didn't need to run to the cars like a certain tire chain makes their techs do for each customer. I miss those days of hard work.
0:25 you say “wheel on a tyre”. I’m sorry that’s annoying me cause you put a tyre on a wheel! #grammarpolice
Who saw the squirrel?🥴
huh
steel on steel >>>>>>> rubber on asphalt
A lot of thought and effort had been made for this high quality video. So unlike many that are quickly churned out. It deserves to get more views.
10:02 I’m a tire guy, that is used to hold the tire in place and open it up, usually for patching nails and other punctures. The shop I work at still uses them (although ours is much more compact), it’d take at least twice as long without i
Hi Andrew, for 4 months I've been waiting for your next video. You are doing an awesome job!
I have been looking for this information for quite a while. I am surprised you did not mention tire age. Tires have a manufacture date on them as unused tires break down after several years. Great video.
Andrew thanks for an even deeper understanding of tires.
These kinds of videos make me appreciate engineers and designers
10:02 someone else probably already said it, but this is to spread the tire open to install a plug when the tire gets punctured. Allows the tech to fit a grinder in to rough up the surface so glue can stick better.
Just found you, watched this video and the one before, very pleased that there will be more content like this! Super educational and awesome!
08:03 squirrel lol 🐿
I appreciate the research that goes into these videos, well done!
Great vid.
The thing about making the car crash tests harder is it makes it harder to pass, making it harder to produce, making the end product much more expensive.
We should always ask about an improvement to make something better is, "At what cost".
Sometimes it is not worth it to have to pay $80,000.00 for a truck. Or $25,000.00 for a modest car.
Sometimes it is not worth it to have to take the time for technology to reach the expectations for the improvement to be implemented.
Sometimes it is worth it to not to have to pay or wait for it... At least give us the option.
I love this video format. Subbed. I look forward to your farm equipment videos!
This was a very fun video for me. I started changing tires in 2003 and the tire industry has come a LOOONG way in regards to servicing tires and wheels. It’s simpler yet more complicated than ever. There are more tools available to help change tires but the cost for this precision equipment is extremely high and all require quite a bit of hands on experience to use efficiently without sacrificing quality or damaging your tools.
Holy moly, this video is so well made. It had my full attention and interest from beginning to end. Well done, dude.
Not an engineer, but the ingenuity blows me away every single time. From Machining to Coke Cans, I'm honestly shocked the human mind has the capacity for such elegant solutions. God Bless.
Bro doesnt make videos like this often but they are QUALITY. Good job, Andrew!
