That guy looks like he should be the older mentor character in an anime.
Perhaps Rayleigh in One Piece?:)
+Scrustle It looks a lil weird and I think that's what most people would think, but I like it. I think it's cool for the president of a business to have some art to them and not just be a suit. I bet this guys has a cool house.
+Scrustle LMAO

You mean ryosuke takahashi? 😜
+Paul Kim Just give him white hair,more beard and some scars on the eye!
please never stop this series haha loving it!
When your friend takes 8 steelies and uses a lathe, calipers, and a harbour freight welder to make 275s.
I really enjoyed this video. The presenter was certainly an expert on the subject (as are all the presenters for /ENGINEERED), but he gave an overview of engineering concepts in such a way that the viewer was not overwhelmed with depth or confused by specificity. Really good work guys keep it up
Disregard everything. Acquire steelies.
I'm surprised how much hate there is in the comments for this video, he's explained things really well, I feel like I've taken something away from this.
Because people are stupid.
Great Video!! Very well explained! Very interesting!!
Thank you!!
This series is awesome!
It is really cool of Mr. Peltier to take the time out of his day to make a video like this. It's also comforting to know that in his position, he has the engineering knowledge behind their product rather than just the marketing or business managing knowledge involved with running a company.
These engineered posts are the best part about /Drive.
So what he's saying is that I should buy Rotas?
Hahahahahaha fukn yes gold
+benjamin reynolds Vossen too
+benjamin reynolds Yeah the 3 Piece Rotas
+Subi Slide stop...
+benjamin reynolds too expensive. You need XXR orJapan Racing wheels :p
Amazing video drive. And thank you for taking your time Alan Peltier for explaining simple things to us.
Awesome video.
This was a pretty good general explanation and insight into the process of Rims/wheels.
Great video. I leaned some new things. Thanks for all yalls videos 👍🏻
Thank you Alan Peltier for this video! You gave me a great education on wheels! Thank goodness there are smart people engineering safe, quality products for My hot rods that we are building! I contacted your company and was given helpful advice and will contact a local distributor for fitment and measurement for HRE wheels.
This is an excellent video with very simple explanations of complex engineering concepts. This dude knocked it out of the park.
You guys are on a roll with these informative videos! Keep up the great work.
I just got "Enkei rpf1" 18x8 rims (215/45/R18 Tires) for my 2002 Subaru WRX wagon, they look truly amazing & are very popular with performance motorsport. The thing you need to keep in mind is the Enkei RPF1 can still be damaged by potholes. I'm very happy with my purchase, Enkei makes amazing wheels.
+wedgoku Any wheels can be damaged if you hit it hard enough. The angle, depth of the pothole, speed, etc are all variable. Difference is though that you'll bend the barrel and be able to fix it. Fake wheels can crack or worse. Enkei's line up is pretty great!
Finally somebody explained Unsprung Weight in a way that I got it. Thank yououou! Loving this /Engineered series so far
Kudos, /Drive people. I love what you're putting out there lately.
wow! thats a seriously good video! and not only that i just snug a peek at your website and it seems like you got some nice stuff over there. count me in!
Very informative and anybody into performance parts, or tuning their car, this should be required watching!
"There are the types of wheels , a cast , a forged and a cast fhlfgrt wheel" 0_o
I think what he said is a Cast-Flow wheel.
he said cast flow formed
What a fantastic presentation. Thanks for that!
Great show. I'm starting to really enjoy this series.
Appreciate Alan taking the time to do this. Learned a lot. Holy crap is there a lot of physics and materials science to doing it right. Good to see smart people making excellent products.
I'm signing up for Red so hopefully y'all get paid to keep doing this. Hoping RUclips doesn't pull an RIAA.
Great job on this video. Keep em coming!
Very well explained. Too many people and companies don't realize how important wheels are to the performance of a vehicle. Specially a motorcycle. They are so engrossed in the looks yet have no idea of the function and performance. They wind up building pure (great cool looking) garbage that would be better suited for a boat anchor.
Great videos guys, very informative!
cool video, i appreciate his honesty at the end. I love HRE wheels, i will buy a set when i get a deserving vehicle.
Probably the best youtube video I've ever seen... I wish all of them where this polished.
Great video! I like how although it was done by hre, there was no point where I felt they were trying to sell their product to me. Very informative!
great video answered a few questions i had about wheels
Very informative. Big thumbs up for Drive and HRE Wheels
Well executed presentation. A+
As a nerd and engineer, I love this /engineered series! keep it up, /Drive!
I like all the other drive shows a ton, but this is easily my favorite! I've always been more into the science and engineering of cars(especially aero) more than power or speed. These segments are fantastic!
currently on my 6th set of HRE's! awesome wheels and awesome people
An excellent and informative vid, cheers
VERY informative, Thank you
Great stuff 👍🏼
awesome! guy knows his stuff and well explained!
All nicely explained, only thing I'd add, regarding rotational inertia, is the effect on handling. Following the rule that a force in motion wants to continue as is, a lighter wheel doesn't resist changes of direction as much i.e. when you turn.
Definitely looking into wheels for my Ecoboost Mustang; this was insightful.
That car is not worth aftermarket wheels.
HRE makes some pretty amazing wheels, love this company!
Loved this video, well demonstrated and informative. Just wished had video of the processes, not just explained
Good info. Thanks DRIVE.
For my Fiesta I put all my trust in the guys at OZ and Sparco. However, in NFS Shift I also used HRE wheels because they look ace in black. And fast, somehow. And now that I learned that you build racing wheels (for Rum Bum Racing, even
The ENGINEERED series is awesome; thanks.
Coolest segment so far. Probably because it's the one, as an average Joe car enthusiast, I can relate to the most.
Thank you i wondered what black magic alloys/cast rims where now i do thank you mate
but is a 3 piece wheel structurally inferior to a one piece wheel?
and do the shape and amount of spokes affect the strength of a rim as well?
+boy638 "but is a 3 piece wheel structurally inferior to a one piece wheel?" No. "do the shape and amount of spokes affect the strength of a rim as well?" Yes. Obviously the more mass you retain in the spokes the stronger they will be but then its a heavy wheel. you need to balance it out. Lose as much mass as possible while maintaning a good / safe margin of strength and durability.
+boy638 2 piece rims are best... beceause well 1 piece barrell
+Shabbernigdo Xingjian
Yes, that is why Ferrari wheels have so few and thin spokes and one can find the same design in BMW M-car wheels.
+Fast Er Alan showed us their stress simulation software, and explained how spoke design is essential. Wheels can have thin spokes, as long as they're strong in the right places. Engineers can build strong wheels with a variety of spoke designs, but changing them 1mm can have a big effect on strength, so it has to be done carefully.
Also, they make look thin when viewed at 90-degrees, but the spoke is thick/deep. There's a lot of factors that go into designing a strong wheel. BMW and Ferrari wheels are TUV certified, so they are strong.
+boy638 Yes, a bolted connection will be either heavier, weaker, or less durable than something that is one piece. The point of a three-piece wheel is flexibility and manufacturability though, not structural performance. The difference is not huge though, so don't worry too much. Just be skeptical if someone is selling a 3-piece or 2-piece wheel that is claimed to be lighter and stronger than a 1-piece wheel of the same quality.
I love Advans. For me, personally, they make the best looking racing rims (not the lightest or the most sophisticated) on the market.
This was great but if you ever come back to this subject I would love for you to spend time talking about Off road wheels as well as heavy load wheels ie trucks and buses. Thanx for the cool vid.
9:53 picks up that massive wheel like it's nothing haha. I was like whoa that is super light, or he's really strong! 😂😂😂
I'm on my second set of HRE wheels (forged). The runout and balance of these wheels are without peer. Yes, they're going to put a dent in your bank account, but they are the finest wheels I've come across.
11:12 the way he says two piece makes me laugh. "I dont have a tupeece wheel..." Great series though, I'm loving this!
I love my Nismo LMGT4's.
Very Nice been waiting for a Vid like this......
I worked for a small wheel manufacturer recently, all cast, and while our machining was top notch, our foundry was garbage. We'd get about 75 good wheels out of 1000 casts depending on the cast. I really wish we did forged as well.
enjoyed the video
not the best episode from /ENGINEERED... at least, he explained the disadvantages of heavy wheels. What he didn´t say (of course) is, that the best method to save weight is to use the smallest wheel possible: the one just fitting over the brake calipers... Rubber is lighter than any metal including aluminum.
Next point is that 2 or 3pc. wheels don´t have any technical reasons anymore, they only exist for the looks and their (outdated) reputation due to their sporty heritage. In the past they had no other way to make forged wheels. It wasn´t possible to forge a whole wheel including the barrel, so they had to forge the single parts and bolt them together afterwards. Nowadays it is possible to roll out the barrel from a forged pre-form, as he described. And this is way more economic and superior to 2-/3pc wheels, because the extra meat for the screws and the weight of the screws are adding substantially to mass on the outer diameter in comparison.
Best/lightest wheel: smallest one possible, single piece forged. Everything other is due to style or limited budget.
the advantage of the 2 or 3 pc is that they can be made in more available sizes than the 1pc.
Youve ignored the steering benefits of high aspect ratio
light weight wheels can increase MPG by a lot too! when the time came for choosing new wheels and tires for my commuter car that is mostly used on the highways. i gained 50 miles per tank! same wheel and same tire sizes just lighter.
+barnettzack How much weight did you save on one wheel?
+barnettzack I experienced the same thing. I dropped close to 10 lbs of each corner and my MPG substantially increased.
+barnettzack Totally. I went from 23lbs down to 20.5lbs on each corner (rim alone) and easily gained 2-4mpg
+barnettzack its rotational mass and unsprung weight it help with handling and acceleration as well as economy saving a few pound of weight have big changes since your reducing 3 pound of weight swinging around and around that amount of wasted energy is transfer to the ground making more energy per rotation
these engineered videos are the best.
So how much lighter are those HRE wheels over the stock wheels on the 918 and CGT both shown at the intro???
HRE's are the best! They are the standard!
This is why i love Drive, I'm always learning new things.
Be my personal teacher?
All all these great vids just to whet our appetites to pay for a paywall version of these to come later?
+TheBurnout *Are
+TheBurnout It looks like these videos are the same as the ones on Drive+ they just come out months later than the Drive+ ones do.
+TheBurnout
These are old videos from Drive+. They show them here after a few months. So you can have Drive+ and see them right away or wait a few months.
he does very good at this explaining
wow i cant believe i learned so much from the man behind HRE himself, thanks /drive. cool shit.
Great video
HRE is not for everyone it's for people who appreciate excellent engineering.
I love these videos!
In NYC people love their thin tires but hate it when they blow going over all the potholes here.
Didn't know Cruella De Vil was in the wheel business.
?
H-Re wheels are subject to Germany's comprehensive TUV requirements as many of there model wheels are sold there.High quality as a baseline ..... works for me. +993 Nice wheel composition details! Thanks, M/S
That was great!
I wish /Drive would switch to broad tip markers, like a paint marker (One4All) it would make the question writing look so much more neat and professional. If I get the chance to help make one of these, I'll bring a set.
Great Vid!
this is a really good video
oooh! 6061 triple butted aluminum. I can safely say my track frame for my fixie is as high quality as a high performance race/road wheel by HRE. But thats not my only excuse. Im proud of this because I knew how nice 6061 was before I found this out.
I love how the video is titled 'Why Crappy Wheels are a Bad Idea' and contains nothing on the subject of crappy wheels.
is that rogues brother??
for my street cars ive always loved simmons 3 piece wheels.. the look sick... and for my hotrods i love American Centrelines.. old school and light
HRE rocks! But so are BBS and OZ!
What about the wheels on Koeniseggs? I know it's one company and they don't use normal methods, but they wrap carbon fibre around a tub to produce their wheels.
Fancy Shit for a fancy car
+Carl Sagan Those wheels are some godlike shit. Maybe they are the only one in the world using that method. But ofc you need some next level thing on those next level cars.
+Jason Cheaper then buying new rims for your Veyron after 3 tire changes. Those cost you 120.000
+BossTuned I know "wrapping" wasn't the correct term to describe the adhesion of prepreg carbon fiber. Still thanks for the video, I watched the 'How it's made' video on the koenisegg one:one
+Carl Sagan the sheby gt350r has carbon fiber wheels too which is a big step for American car companies
HRE's crack and bend too if you hit something hard enough. I have 3 different sets on 3 different vehicles, the 3 piece stuff uses triangle barrels. ive seen their monoblock stuff bend too. no wheel is safe from bad roads.
Agree with this. I won't buy reps anymore after my ESR SR02's split in half going 5 mph over a speed bump
"Americans are a bit tougher" AKA we are all rolling in a backstabbing system driven by pure profit and little concern for the satisfaction of a customer. Thankfully there are still companies like HRE that sell a quality product and still turn a profit.
I see these wheels all over the place here in San Diego! they're beautiful
+Eric Pettersen one reason might be their close proximity to SD, theyre in Vista.
I remember when Rotas first came into the market. They were a cheap alternative. I'm surprised how pricey they are now. Their stock must be doing well?
The title to this video should be: Why a crappy wheel is a bad idea or Why crappy wheels are a bad idea. Good information on the wheels though.
Question for anyone who could possibly answer it: I have a 2008 BMW E90 328xi with stock 16" wheels on it. I am looking to change those rims and swap them for a set of matte grey 19"X8.5" Verde V99 Axis wheels. Is that a feasible size to put on my car? I checked that they would fit, but would it be too much of a size increase? Would it negatively impact the handling or improve it? Thanks to anyone who answers!
God I love these series.
how does this change for offroading, since having more unsprung weight keeps the rubber on the ground keeping the vehicle more stable....
I miss my Enkei racing S split rims. Lightweight goodness.
I would be interested to se how all this differed from an off-road type wheel like from method racing wheel
That light blue sharpie likes to dance :)
He didn't really explain about why crappy wheels are bad. He just seemed to talk about the different features of different wheels.
I noticed he said they start off with 6061 O. I'm going to assume there is some type of heat treating after forging.
Anyone know what kind of watch Mr. Peltier is wearing?
