STOP Setting Tire Pressure to 32 PSI! (You're Destroying Your Car)
Embed
- Published on Mar 15, 2026
- 🚗 STOP! You've been setting your tire pressure wrong your entire life! That 32 PSI on your door sticker isn't optimal - it's actually destroying your tires and costing you thousands in premature replacements and wasted fuel.
💰 THE SHOCKING TRUTH: • Door jamb pressure = minimum for MAX load (not optimal for daily driving) • Proper pressure = 38-42 PSI for most cars (10-15% below tire max) • Wrong pressure destroyed my $800 tires in just 18,000 miles! • Correct pressure = $300+ savings per year in fuel & tire costs
🔧 WHAT YOU'LL LEARN: ✅ Why manufacturer recommendations are too low for normal driving ✅ How to read tire sidewall markings for optimal pressure ✅ The math behind fuel economy improvements (6.4% increase!) ✅ How pressure affects tire wear patterns and safety ✅ Why TPMS lights are useless for maintenance ✅ Step-by-step guide to find YOUR optimal pressure
⚠️ IMPORTANT SAFETY WARNINGS: • Never exceed tire's maximum rated pressure • Always check pressure when tires are cold • Adjust for heavy loads and seasonal changes • Performance cars may have different requirements
🎯 MY RECOMMENDED PROCESS:
1. Find tire max pressure on sidewall
2. Calculate 10-15% below maximum
3. Start with door sticker + 6 PSI
4. Monitor wear patterns for 2-3 weeks
5. Fine-tune based on center vs edge wear
💡 REAL RESULTS FROM 35,000 MILES: • Fuel Economy: 26.4 MPG → 28.1 MPG (+6.4%) • Annual Fuel Savings: ~$130 • Expected Tire Life: 60k → 70k+ miles • Total Annual Savings: Nearly $300
🔧 TOOLS YOU NEED: • Quality digital tire gauge ($15) • Monthly pressure checking routine • Tire wear monitoring
📊 THE SCIENCE: • Under-inflated tires = excessive sidewall flex • Contact patch spreads wide, center lifts • Weight concentrates on outer edges • Result = 3x faster edge wear
This isn't just about tire pressure - it's about understanding how car manufacturers prioritize comfort and liability over optimal performance. Once you know the truth, you'll never look at that door sticker the same way again.

I didn't know AI buys tires and owns cars.
whole video is garbage
Yup, sounds like BS to me.
Yep. Had my suspicions straight away. Low subscriber count, high views, then checking the channel they're putting out a shit-tonne of videos. Fuck AI and fuck youtube, man.
Get to the point
Exactly
If tires are too high pressure, they wear out in the center tread. Lower pressure the inner and outer tread
yep. set tire pressure for even tire wear.
I thought that only applied to the very old bias ply tire technology, not radials.
yep, I think the video has it backward, sounds like his car may have needed ab alignment instead of more air.
@Winston-h7cAlignment does not affect both edges.
@km4hr, for the most part, tyre technology doesn't matter.
Somebody's AI can't tell the difference between a dual gauge and a dartboard.
Always check the tire pressure when the tire's are COLD
I DO BELIEVE HE ALREADY SAID THAT. 😂
@TRICK-OR-TREAT236 I run a fleet of Kenworths trucks and i Know about tire pressures how it matter's you see a lot of people checking tire pressure at the service stations after driving and that's a mistake the tire's are hot from driving from home to the service station
@TRICK-OR-TREAT236It can’t be stated enough.
Nope. Check when hot as the way you drive it. Do you drive with cold tires? Nope.
The tire casing will expand differently and so when your tires warm up the tire temps can be very different. You don’t want to drive all day with different temps in each tire
@nihadsarajlic787 Absolutely 100%+ correct. Still amazes me to this day the millions of drivers who still carry out this practice at fuel stations and don't realise how counterintuitive it really is. Still, in an emergency ok until it can be done properly when cold. I always keep a foot pump in the boot.
I'm 72 year old multiple vehicle owner since the 1960s who has always done all his own tire rotations and changes, snows to summers and back again annually and am always keen to husband our tires for maximum duration of service and safety.
Tire pressures posted on the driver's door post are in part set to attain a certain ride quality in the vehicle. There is a little leeway above and below depending on the tires set purchased.
If one's tires are wearing evenly, don't change a thing. I usually start at the recommended pressures posted on the driver's door post with every newly acquired vehicle and see how it goes.
If one's tires are beginning to show wear on the outer edges prematurely, increase tire pressure above what is recommended on you driver's door post.
If one's tires are wearing prematurely in the middle tread section, they are over inflated. Reduce pressure below what is recommended on your driver's door post.
I find I generally settle at 1 to 3 pounds above the spec posted on the inside of the drivers door post and get even wear right down to the last gasp of said tires on three very different vehicle types at this point in time.
If a tire or tires begin to show wear only on one edge, get an alignment pronto.
If a tire's tread is cupping, blocky or wavy, rebalancing is needed immediately or there is a steering and suspension linkage wear problem at hand. They both require immediate attention in order to protect one's investment in a well performing, matching set of tires and for your personal safety.
A matched set of tires is the safest set of tires for most vehicles. Mixed sets of tires, not so much.
For better MPG, overinflation is the direction to go, but premature center wear, poorer traction, reduced lateral acceleration and a harsher ride quality may be the detectable results. MPG gains will be minimal. However, if one is driving on dangerously deflated or constantly leaking tires, MPG can suffer greatly and compromised safety in handling and catastrophic failure of said tire(s) is a real danger.
In many vehicles, dangerously underinflated tires to the rear are often not obvious. One could be riding around on 10 psi and not see anything out of the ordinary. Said tire will run extremely hot, perhaps to the point of fire danger at highway speeds of long duration. The dangerously underinflated tire will also fail you in any emergency maneuvers or hard cornering one might encounter. Check tire pressures routinely. Do a visual tire check each and every time one approaches one's vehicles. It is best to make this an ingrained habit.
Good luck and good driving to all.
Tis amazing to see only 11 thumbs up compared to other responses, I guess persons didn't have the time to read, but this is a tonne of wisdom from a truly experienced driver her imo. Kudos.
Very well explained sir, hats of to your experience and an eye for detail 👏
Such comprehensive knowledge even a mechanic won't tell you or don't know or a tyre shop fella won't differentiate the tyre pressure between a cold tyre & hot tyre. Cheers!
I had to use AI to summarize your comment lol. Because to get through it all I would have to rotate phones 😂😂😂 all jokes aside thank you for sharing!
Under-inflated tires lose stability, especially in lateral direction. I had a puncture in bicycle tire, slowly deflating, and a few hundreds meters until home, I continued riding. At a slight turn I fell down due to tire deformation.
door stick define the minium pressure while the pressure labeled on tyre define the maxium.
32-34 psi for nearly 40 years I never had a problem
Yep, if you keep them inflated, balanced, and rotated, they will last 60k miles.
That was for 14 and 15 inch tires. Bigger tires need more pressure. For my 16 inch tires, tire shop advised minimum of 38 psi.
@constitutionalist3931 the tires will last for 60k but the video addresses uneven wear on the outer edges with the numbers on the door
Maybe you were just unaware of the problems . . . I always wondered why the outer edges of my tires would wear so much fast then the middle . I thought it was the tires themselves
36 for my truck and 34 for my car (for 20 yrs) and also never had an issue.
Video like this is the problem with internet.
You said it, Bert.
Ha ha
Too much pressure?!
Eshitification.
AI sucks....misinformation for $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
I call bull shit. Biggest load of crap I've ever watched.
I trust HONDA'S little sticker ...not a you tuber
so "hes" wrong about what the tire pressure on the sticker means?
RUclips allows all sorts of false information to be posted and do nothing to suppress it. It's criminal!
@markn3586how do you know its bullshit?
@markn3586 Yes
This guy is off on his information. If you have more weight in your vehicle you want a higher pressure. If you're getting your edge burned away, your pressure is too low. If your weight over all is low and your pressure is high you will get a center balding and not a side balding on your tires.
Center balding - pressure is too high.
Side bolding - pressure is too low.
I thought that sounded backwards.
BlueDroneBlues mechanic here. Correct on all counts. Cheers.
Agreed, thanks for taking the time to clear that up.
"This guy" is AI.
It's not a "guy": It's an AI bot whose only goal is more clicks to make more $$$. It doesn't care in the least about people or what they do with their tyres: it only wants to get noticed, and get more clicks. So just down-vote it and mark the channel "do not recommend".
Did anyone mention proper wheel alignment?
I was thinking the same
Wheel alignment was likely the issue.
Bad wheel alignment will only affect one side of the tyre
@whizzer2944that would be incorrect.
@hughmorris33 And your comment would be correct.
2:21 Amazing driver doing that power slide within a tunnel !
The psi rises as the temp goes up ..if you run 35, on highway your going to 38,39
Nitrogen is more stable at various temps, that's why aviation and industrial apps use it.
That's factored in - the door decal says the psi is for a cold tire reading.
@rogerrussell9544True but a waste for regular cars and suv's. Simply check the pressure.
@human1513 Agreed, Earth's atmosphere is 78% nitrogen. Unless you race or fly a commercial aircraft 100% nitrogen is wasteful.
which is good
If your wheels are wearing on one side you need a wheel alignment.
And or some of your suspension parts (control arms) may be worn out and need to be replaced.
for most of the cases, it's barely the tire pressure.
Not necessarily. Aggressive driving style will definitely cause "one sided" tyre wear.
Yes, worn control arm bushes, radius rod bushes, ball joints etc can also cause irregular tyre wear, as can stuffed dampers (shock absorbers) , however the greatest enemy of tyres is underinflation, but there is a crossover point as excessive inflation reduces the suspension that tyres provide and reduces the contact adhesion pad area. Unfortunately, there are too many wannabee mechanics giving stupid advice on YT and you are one of them.
@doludeli, That is BS. Under inflation is the NUMBER ONE cause of premature tyre wear.
You are just talking crap. To test my advice, set one front tyre on your car to 20 PSI, and the other to 45PSI. Drive around for a month and see the difference. The 20 PSI tyre will have worn rolled edges, and the 45 PSI tyre will look perfect by comparison. Go on smarty pants, try it and then come back and remove your stupid comment.
@Jamie-c2l “Underinflation” is not defined as following the OEM specifications on your door panel. I prefer a few PSI higher, since I have performance tires, but if you’re defending advice to inflate your tires to 50 psi, I would suggest anyone reading these comments get a second opinion from their mechanic.
Alignment is everything
master mechanic here. This all bullshit. Have the right speed rated tires on the car according to the sticker. Inflate them to what the sticker says COLD. Your tires will be fine if your alignment is correct. Wear on the side of the tire is because the alignment is off. Saving a dollar on a fill up is not worth the hard ride, if you even save that.
Correct.
Why the right speed rating? We had a Toyota , I used lower rated tires and never had a problem. I didn’t need tires rated at 100 mph or whatever it was
Agreed.
This is all true with the exception if you put on tires that are not the same as the OEM tires. Particularly if they are a different size. I learned years ago that rather than waiting for the tires to wear for a while to see how even they wear, I ran a chalk line across them and drove them for a short distance until I found the chalk wear evenly.
💯
Needs a accurate pressure gage.
The common stick pressure gauges are not accurate enough to be useful.
@Scramble-electron-890 How do you know that?
@Greg29 I've watched videos of the factory workers saying they were told to send defects through, so the boss could reach the production goals on the stick type. As a former factory worker, it's believable.
I use 3 different gages to crosscheck accuracy of each. Don’t buy a cheap one
@Greg29 you really want to put your life on the line with a $1.99 pressure gauge?
"The door stickers say: 33, 35 PSI"...
If your tyres wear on both outside edges of tyre,you need to increase the pressure.
or stop driving so fast around corners, unless they are racing tires.
So how does that apply to blow up dolls? Asking for a friend.
I said the heck with all this and just run my car on the rims.
At least everyone can hear you coming.
keeps people employed, good on you.
Figures they tell you that so your tires wear out sooner which is what they want.
😂😂
I have Michelin cross climate 2 tires and the installer said 40 psi is a better pressure and I’ve kept them there for a year. Thewear is even for me.
The Cross Climate 2 I bought for our 2022 FWD Highlander paid for themselves two weeks ago during that ice/sleet/snow storm. We had to get out in it for work and drove all over town with absolutely no, none, zero issues. I am sold on those tires! I just wish they made them for my truck!
Great installer! Recommend you recommend him. ;^)
I have a bad back, as a 73 year old ex truck driver. I drive 5,000 miles a year. I run about 30 psi in my hard riding Corolla, tires still will dry rot before tread is gone. Car rides bad enough at 30psi, 35- 40 psi will rattle my dental fillings right out of my head!
Hahahahaha
Stop using Micheliens
Need to use rubber conditioner.
then u need a Cadillac
@johnswanson3741 Your guess that he's running Michelin's is probably right! I bought a set, and they dry rotted in 2 years, and when I got another set, those dry rotted in 1 and a half years! NO MORE MICHELIN'S FOR ME, EVER!
Rough pavement describes just about every road in the northeast. Especially in the winter, with the frost heaves and embedded ice shattering pavement.
I do 40 PSI. I get good gas milage and they wear just fine.
Same here
i run my tires at 40psi on 60k tires i got 94 k on them and they weren't all that bad just decided i got that much mileage on them i was probably rolling the dice
40 PSI works just fine for average driving, and is a very safe PSI!
my sticker says 36. 36 feels like slop. i do 40 as well.
You're also creating a dangerous situation because your sidewalls don't have the proper flex to absorb the shock from bumps and potholes. The air in the tires gets squeezed, and could cause a blowout.
Here in Europe the door stickers have multiple pressures for different loads
So does my Outback which was made in the US.
They still let you have cars in Europe?
In Europe, do they include tire pressure information in Arabic ??😅
@californiadreaming9216hahah ok you win
@zoso1123 Of course, why wouldn't they?
i change my tire pressure every time the weight in my car changes.
I've been driving my cars with tyres set at factory suggested settings. Never had a problem with uneven tyre wear provided geometry set correctly and wheels correctly aligned.
@mattg8415 There are no "free lunches" when it comes to automobile engineering. Higher tire pressure means more fuel economy because of less rolling resistance, but the less rolling resistance the less grip your tires have... meaning you gain the fuel economy at the cost of traction and control. It certainly isn't "free" fuel economy.
Exactly it’s through observation and time you find the sweet spot 👍🏽imao
@kingduckford not so. That's an old wives tale. Unless the tyre is grossly over-inflated, increasing the tyre pressure slightly increases the grip. The contact patch gets slightly smaller, meaning the rubber in the contact patch allows the small rocks of the sealed road push into the tread slightly more, increasing the grip. This isn't to be confused with sidewall deflection. Tyre grip and dynamics is incredibly complex, and the old rule of thumb hasn't been true for decades.
Absolutely correct.
I see what the problem is, you spelled tire incorrectly.
Don't forget to change your summer air in the winter and again in the spring.
Autumn/ Fall doesn’t exist where you live 🤔
It would be really nice if tire manufacturers would make the tire pressure statement on the side of the tires LARGER, It's so hard to read especially in shade.
They can't. the tires can be used for dozens of cars. Each car may have a different pressure.
Pressure depends on vehicle weight etc
But that is the MAX pressure loaded for those tires, not normal running pressure. But you are definitely correct. I just went out to look at my tires and even with a flashlight and my glasses I couldn't read the crap.
They won't! They want to sell more tires!
It's a fad these days to use small print and make everything hard to read.
Hey everyone; it's not a person. It's a computer. You're arguing with a computer. Sigh... I guess that's where we are now. Double sigh...
Noooo, thats NOT true. 'They' (we) are talking to all of US who read the comments - thoughts and opinions. Sigh... constantly from reading dumb comments .... sighsighsighsigh,sighsighsighsigh, sighsighsighsigh......... sighsighsighsigh ........ SEE?
Oh shut up with your stupid sighs.
No, the uploader will answer replies. AI voice is often better than human. A human wrote the script.
Hey he said he has a car. He MUST be a human ….or an alien 😮
🤫 Don't tell them that. They think they are winning the argument.
My husband raced cars and has always said this!!
@hadassah8549 Yes but racing does not relate to driving 100 miles in an SUV on a Sunday afternoon on a highway to visit Aunt Mable does it.
A chalk test is a good way to determine your tire wear condition.
How do you do that?
@terry_willis I think you draw a chalk line across and look for where it wears off and where it doesn't but I want to know exactly how they do it and how long etc. because it is a great idea
@terry_willis ruclips.net/user/shorts11BHku4URKo?feature=share
Shut up unless you explain what the chalk test is and how it works.
@justgivemethetruthyou are an ass!!! Why don't you just take a couple seconds and look on grok or chat gpt assuming you are old enough and intelligent enough to do that... I CAN explain it, but sometimes people have tips and tricks so my reply was to someone else and was clear that I was curious how they did it. There variations and just bc I know how doesn't mean they might not know a new variation.
0:56 the door sticker has nothing to do with what it says on the side of the tire
Im pissed at the guy that sent this to me because he should know better...hell, he's an aircraft mechanic!!!
Of course not.
my tyre guy told me this recently.
I run 38 front and rear in my Forester XT.
Same with my Crosstrek
Too high tire pressure wears the center of the tire tread.
Too low tire pressure wears the two outside edges of the tire tread.
Everything that is posted on RUclips is not fact.
True. It's easy -- check your tread depth every few 1000 miles, and adjust pressure accordingly.
I saw something about that in an old book. It was true for bias ply tires. I think that radial tires keep the tread more flat side to side so this may not apply for most modern tires. Problems with wheel alignment often cause uneven tire wear. Both toe in and camber settings are important for long tire life.
@andyb1221, modern tyres are still affected by pressure, maybe not as much as older tyres, but pressure vs. load is still important.
@andyb1221 it still applies, but the tire pressure on the side of the door is for the tires that came with it not a different style or manufacture. always set pressure according to the specific tire on your car based on the pressure posted on the tire.
Somebody needs to work on their listening skills.....
The first two times the video shows the door sticker, the narrator says 32 PSI, in both cases the 32 PSI is not on the door sticker.
AI clickbait garbage
AI is so stupid.
For the first part of the video he says to use higher pressure because the car usually only has the driver and no cargo. Then at 5:13 he says that more weight needs more pressure. Totally contradicting himself. Every car manufacturer says to use the amount shown on the sticker as do the tire manufacturers.
I run 36 to 38 psi on my half ton pick up with Michelin road tires. It rides a bit harsh when the truck is empty. I don’t care about a slightly harsh ride. I care about tread life and gas mileage.
My 1/2 ton recommends 35 PSI. The tires wear evenly at that pressure.
Your are right. The only problem with that is using Michelline. You are being ripped. Expensive for nothing.
@saeed6811I’m running they too. I got a good deal on them at Costco.
@saeed6811Why are they so popular then? My experience with them has been great.
@rond1949they are popular because they spend money in advertisements and you were born seeing the big fat ringed doll from Michelline everywhere you go.
Tyres is about TIME, WEATHER and TREAD WEAR. Air is just one factor. I am from the middle east and we change tyres in every 2-2.5 years. Anything past that is dangerous.
Having said so, buying a 400+$ Michelline or GoodYear tyre is worthless. There are brands such as BF Goodrich, all terrain tyres, they do the same job for a 180+$. I have even tried the cheaper chineese or Korean tyres. They give me 2.5 years no sweat for 75$. As long as they don't make noise on the tarmac road, am good.
I stopped used expensive tyres for a very long time for my Chrysler 300C, Chevrolet pickup truck, my wifes Chevrolet Traverse. I think I have enough experience to say so. Even these dirty expensive tyres have reduced their prices to half from what they used to sell 15 or 20 years ago after the introduction of Chineese and Korean market tyers. Michelline, GoodYear, YOU ARE COOKED😂.
I like having the low pressure light on all the time
More AI clickbait garbage.
Isn't that like 80% of youtube these days. That and short useless videos.
This is BS, no doubt!
It may be AI, but 99 percent of what the video taught was accurate.
@stayinformed291399% was wrong
it's basically over for YT
Why should manufacturers bother giving recommended pressures if EVERYBODY knows better?
Liabilities. Lawyers and courts. Same reason they have to warn people that coffee is HOT
@robertb7864That makes no sense. They warn that coffee is hot because it really is. With this tire situation, the recommended warning or suggestion isn't what it is. Way different than the coffee example. 2 different things.
government reg red tape.
@trutru9018 Very often my coffee isn't hot enough to burn me. It's clear whenever it's easy to drink right away. Like when one adds a good deal of fridge-cold cream. Yet the warning never says: "Contents may be hot." Which is fine.
Listen again to what was said. The manufacturer tire pressure is the minimum for carrying a decisive weight. Most of us drivers take it as the maximum pressure, which is wrong. Almost everything that he is saying I have experienced it with my car. When I put the pressure up to 36-38 above the 32psi I get so much more mileage and easy handling than at 32 psi. Afraid of a blow out keep the tires at 32psi when the tires states 44psi which is different from the door sticker 32psi. Just try it for yourself and see what happens.
It is nice to know that the tire knows what car its going on and the weight is the same on all 4 tires...B S. One of my old cars has a tire pressure recommendation in the glove box. It says 15 lbs front and 24 lbs rear. Here is the deal...tires back then were bias-ply not radials. People would put 32 lbs in all 4, the car would bounce out of the road and wreck. The car would have a terrible reputation and be in a book "Unsafe at any speed". I now put 24lbs in the front and 32-33 in the rear. The way those numbers came about with radials is: Use the new tire pressure, be on a smooth level concrete surface. Put baking soda in the front of the tires and roll/drive the car over the soda, look at your tracks and make sure the tires show even pressure. Simple. Why the difference in my car? Engine in rear, weight on the front is about 500 lbs on each tire. Rides and handles great. I would think rear engine Porsche has about the same weight ratio. This video is BS. One moron front end place used to put 45 lbs of pressure in all tires. A police car actually bounced off the bridge and plunged 200 feet below, now has a major bridge named after him.
Also, sitting still and turning the steering wheel to aim it where you are going, wears out the edges, they take the blunt of pressure as the tire wall is weaker than the center of the tire. I always make sure I am moving before turning the wheel if possible.
I watched the wear and adjusted the best pressure
I worked for Goodyear and this AI generated post is nonsense. Use the pressure on the door sticker, set cold. Period.
You do you. Ruined a set of tires running them too low.
Alignment was perfect so that wasn't the issue.
Thank you for that perspective.
Definitely do not trust AI for important things.
Absolutely, but how cold ? Many of us have been caught out by a marked temperature change between early morning settings, and when we come to drive the car in midday sun.
Driving on over-inflated tyres along some truly shocking B roads in the UK is neither pleasant nor fun.
What did Goodyear say when your not running the correct size for the vehicle
@jakezablow6328 Size or pressure setting ? Fitting non-OE size tyres is a whole different ball-game in my experience.
I always go by what is listed on the tire, not the cars door sticker anyway.
The amount listed on the tire is the maximum and doesn't take into account the vehicle that it is on. Not all vehicles require the same pressure with the same tire.
Manufacture tyre pressures are set a low as they can get away with to increase "comfort"
I read somewhere recently that the door jam sticker lists a pressure which is a good compromise between ride comfort and tire wear, so for ultimate tire wear and responsive steering you would inflate the tires to probably about 3 or 4 pounds higher than what the sticker says.
This video is full of errors. Just use about 2 psi above the sticker. Too high a pressure cause dangerous behavior in the wet.
Agree 100%.
Who told you that? I have been running my tires at 42 for many years and drive 80 mph on the interstate. My tires last over 100,000 miles. You've been given false information.
That is incorrect. Always go by what is actually written on the tire itself and not the sticker in the door jam. In the summer months you want to put 12% less than the Max psi that is written on the tire because on summer days it rises 10%. And during the winter months you want to put 10% less than the Max psi written on the tire because it will only rise 8% during those cooler months. You will never go over your Max psi that is written on the tire. For example: say it’s summer time and your tire says.. 50 psi max, so 12% of 50 is 6. And 50 - 6 = 44psi you should put in during the summer months because it will rise 10% (44psi x 10% = 4.4psi to 48.4psi which is under your Max psi of 50).
@mercoreyThis is definitely not true! What is on the tire is simply the max pressure the tire is capable of. It does not take into account the weight of the car - which is key! You need to be close to the pressure listed on the CAR. A little over is fine but if you are 10lbs over what is listed you will ruin your tires and have less traction.
Numbers! What is too high?
"running pressure to low for the car"I thought this was about pressure to high.
I think the video is wrong, many comments pointing out its AI. it even seems to contradict its self if I am understanding it in full. first it says the door jam pressure is too low and to add more PSI, then goes on to say the manufacturer is assuming worst case scenarios when your car is at max weight load which would require higher PSI and that under normal conditions that would be too high, that is contradictory. An above comment is from a "master mech." here is what he said:
@spikespike-j5q

"master mechanic here. This all bullshit. Have the right speed rated tires on the car according to the sticker. Inflate them to what the sticker says COLD. Your tires will be fine if your alignment is correct. Wear on the side of the tire is because the alignment is off. Saving a dollar on a fill up is not worth the hard ride, if you even save that."
this makes sense to me. I have always inflated my tires to the door jam recommendations. yes, look at the tire max pressure to make sure it makes sense before airing up but the door jam should be spot on. I have never had a problem. my tire max is 44 PSI my door jam is 35 PSI cold. driving should raise the PSI a few points which is perfect.
Thanks for the info. Got a 2025 mustang gt with summer tires that’s suppose to be 32. The dealer had them at 40 and I just left it. Drove this spring 250 miles 6 hours and the gauge said 40 don’t fluctuate too much. Been trying to keep them about 35 cold
Try 89 psi all 4 corners. It's the number.
Sounds like he needs a wheel alignment before anything
I usually go 34 or 35 my vehicle.
Same and over time you can get a feel for the right tyre pressure setting, based on overall ride quality. i.e. cushioning Vs controllability.
@JBondy007 It’s that sweet spot.
So do I. Have done it for years. Good safety margin, no abnormal tyre wear. Mileage 55k to 70k tyre life, amazingly. 46 mpg . Comfortable ride. Duster 4x4 diesel.
how ai generated spam with misleading info is getting half a million views is 24h is beyond my comprehension.
I know I'm seeing more of this crap, and it's highly dangerous and misleading!
Exactly. It's sad to see how many comments are saying that they will try this. Stick to what the car manufacturer recommends for cold tire pressure, not what some AI generated slop video says.
I saw it on the Internet. It must be true 😂
Yeah this is bullshit.
@georgelewis3047 so we need 40 psi instead of 30 psi
What if my tires say 50psi but the car sticker says 35psi
Look closer, the number on the tire is the maximum pressure recommended by the manufacturer.
0:11 The sticker says 33 PSI. With your reasoning you might as well set it to 80 because that's what the sticker in you head says. I will ignore your other sticker that says 35 PSI.
But my tires say 80 psi
Wtf?
@commentsedited Careful that you read all the info on your tires and educate yourself before trusting a video with your $800 tires.
The stickers in MY head say you no know what you talky about.
95 is what ours go
@robertrraineyjr967lol I run 50 psi. 80 is max. Cooper evolution MT
Don’t forget about wheel alignment geometry. I always “zero out” my alignment geometry (0 toe, 0-1 degree negative camber), and I get 50,000+ miles from my tires with completely even wear across the tire.
I can almost guarantee he had an alignment issue and that's why he only got 18,000.
Oh man, I did horribly in geometry class. Is there an easier way I could inflate my tires?
@maj8301Sorry Mr obvious can't help you in this situation.
Tell us the rest of the story. What tire pressure? How much load? What are your driving habits?
What donut doesn't read to the tire
mY HUBBY was such a good mechanic..he knew this way back. 🥰i miss him so much!🌹
Hoa your car doing now😅
Condolences
Sorry for your loss. 🌹💐🌷
Sorry for your loss. You will see him again! RIP
May he rest in peace 🙏🏻
This video is 100% AI
and the info is 100% bullshit
I'm curious how you know? Honestly asking
According to the manual:
Always check tyre pressure when tyres are cold.
Warm tyres normally exceed recommended pressures. Do not release air from warm tyres to adjust the pressure.
Underinflation can cause reduced fuel economy, uneven and accelerated tyre wear, and poor sealing of the tyre bead, which will deform the wheel and cause separation of tyre from rim.
Overinflation can produce a harsh ride, uneven and accelerated tyre wear, and a greater possibility of damage from road hazards.
Keep your tyre pressure at the correct levels. If one frequently needs inflating, have it inspected.
What are tyres?
@ElTigreMan "Tyres" is the correct spelling of what Americans call "tires". The U.S. uses different spellings of a lot of words. Like "aluminum" instead of "aluminium". That doesn't make "tires" right or "tyres" wrong. Both are right depending on where you live.
I over inflated my tires and the ride was so rough and bone jarring it just couldn't tolerate it.
I always set the pressure to 39psi. Another warning. Tire manufacturers warn never to point a high-pressure washer at a tire. It can affect the chemicals in the sidewall and weaken the tyre.
Where i live in new zealand most roads use chip seal this is cheaper but it is harder on car tyres than other surfaces.
Can't be worse than crushed limestone.
The idiots in Pa. use the same crap!
Oh great, I got an A.I Bot telling me about tire pressures.
I run my little Chevy spark at approximately 37 -38 psi so far I have 40,000 mi on my original set when I bought the car new
47k miles on original tires. Never went over 35-36. Usually under.
I'm not driving a vehicle that rides like a wood wheeled wagon because the PSI is too high. I drive at 30 PSI. Period! Been doing it for 55 years and regularly get 70 - 90,000 miles on stock Toyota tires.
You were typing instead of listening. And if you arent buying tires that are warranted for the miles you're claiming to get, I say youre lying. Now watch the video and learn something.
Bullshit
Toyota doesn't make tyres.
You are free to do that :)
70k youre yanking our chain nice try tho
I always run 90 psi in front & 120 psi in rear tires. I learned this from another AI video. ;)
I have a feeling that you don't actually learn
@RRr-yl8zrI learned that 140 psi is a bit too much air pressure for a tire. ;)
@targeted1948more pressure in your bike tire means a faster ride and easier peddling. Not a soft ride though. We were always racing around when we were kids. a friend of mine learned that there is such a thing as too much air pressure in a tire when we were riding our bikes one day and they filled up there bike tire at the gas station compressed air pump as hard as it would go. It exploded when he sat on the bike . And that was loud! 😲🤪🤣
@RRr-yl8zrI use to ride an expensive carbon fiber road bike. I would put about 100 psi in the tires. They were hard but the rolling resistance was much less & I could go faster.
@targeted1948yep! Until you overfill them and blow them up at the gas station. The steel belt will actually come flying out of those things 😲😂
I was always wondering about this; thanks for clearing this up.
How's it clearing it up. For the first part of the video he (the A.I. bot narrator) is claiming that you need higher pressure than the door sticker because people usually drive with only a driver and the car no loaded with cargo. Then at 5:13 he says "more weight needs more pressure", totally contradicting what was said earlier.
I have had three cars and always ran the pressure at the sticker pressure and the tires lasted around the specified amount.
So, the claim it to set the pressure higher because the car is lighter, then the claim is to set the pressure higher with more weight. It can't be both.
35 front and back
89Psi in three tires. 102psi driver's side front and 15psi for the spare. It's never let me down.
Yes
Front should be just a bit higher to take the weight of the engine into account.
100% WRONG. what car??? 5000# truck or 3000# two seater, how about a 2300# sports car???
@kopyrightliberationfront2000 I'll make the appropriate adjustments tomorrow morning when the PSI is cold. Thank you for the pro tip!
The one variable not mentioned is road conditions. Snow,dirt,gravel. and pavement
I'll check my tire pressure now ...
Okay. What was it?
If the outsides were down to the wear-bars, you had an alignment issue.
Possibly, but not always. Tire pressure also does that.
Or bad ball joints
Or he took Corners too fast in both directions
The factory set TPMS will be alerted if the factory set pressures are not met
Damn this video is fake.
I run 40 psi despite sticker saying 35. So far so good!
41PSI all day baby cheapest tires in the US lasted 8 years
@WolympusNYCWow!! That has got to be a record!! 💪👍😁
Just be like Fred Flintstone and you'll never have a problem 😂
Here in Phoenix Arizona we’re the temperatures can average 110s during the summer can shred a of 4 tires within 2- 4 years with 30000 on them so you must be doing something wrong if you’re shredding them at 16000 to 20000
Try inflating with nitrogen. Some better tire shops offer this. Dry nitrogen is what is used in aircraft tires and maintains a steadier pressure over a wider temp range.
@markhull5776My compressor puts air that is 78% nitrogen in my tires and it's free.
@markhull5776 Yes, the tire will retain the pressure a little longer than with air. But the leak rate of air is slow enough for me to eaasily keep up with, checking every 6 weeks. Air has about 78% nitrogen already. If you pay for "pure" nitrogen, you're not getting 100% nitrogen. Ultra pure nitrogen is expensive. You are getting something near 95%. Taking your tires from 78 up to 95% nitrogen isn't doing anything at all except slow the leakage rate down a little bit. This talk of improving handling, steadier pressure, etc. is baloney, unless you are running your car at 200mph in a Nascar race, or landing it at the airport at 145mph.
My computer just told this computer that it’s an idiot. I run 33-34. Good results.
I been running 35 psi my tires run 🎯been doing so over 3 decades
My tires are adjusted by factory A.I. but it could be lying to my sensors , just sayin'.
If there's uneven tyre wear on the outside or inside first check thr camber/caster settings and get a wheel alignment
I have been running my Japan produced Rav4 HYBRID at 40 psi since 2022 Great wear 😊 I use lots of urban, rural & highway roads😊
I run my rav 4 at 35,should I bring it up?
Right. The RAV4 is exactly the car driven by idiots who believe this video
At 7:23 why the misspelling? "Underinflased" and "inflesed" . Doesn't anyone proof-read before publishing?
AI produced....I swear its purpose is to continue to dumb us down
No human was sufficiently involved in producing this video to do much of anything.
I work constantly to make sure my tires aren't under inflesed.
The video also contradicts itself. First saying you need higher pressure because people aren't driving with a full load, then later saying you need higher pressure with more weight.
I got my oil changed once and after I left it felt like I was riding on rocks, I stopped and checked the tire pressure and the girl that did the tires put them to maximum which was 80psi lol
You must have gone to a crap shop...perhaps one that just happens to sell tires, too.
@wholeNwonno tires just oil changes
@michaelmaas5544 So they did that to your car. God knows what they actually put in your crankcase.
OMG
It was years ago the cars fine
The recommended air pressure for each car given in the driver side door.
i tried 35psi, the center thread wear fast, so i back to 32psi
This is wrong. Too much pressure results in damage to suspension.
Problem is that you ran the pressure at 32psi and the door says 33psi .. silly ai has no idea
Did the AI voice do this on his AI car?
using AI air.
2:10 That's the stupidest explanation I've ever heard. With a lighter load it actually flexes less. The problem is not driving on a lighter load, the problem is that the pressure on the door is minimum, not optimal. If you drove with a bigger load, if anything the problem will only be exacerbated. F stupid explanation.
I was wondering who else picked up on that.
Your kidding yourself.
There us a whole lot more to this than just mwnufature figuring out minute tire pressure. When cars are built the engineers figure out what the optimum tire pressure should be for that car. They have to calculate best traction , nature of the car, best handling characteristics. At 32 psi is a cold tire pressure, not so when the tire is warm it changes quite a bit. Inflat the tire to max can result in over inflation , sidewall seperation, tread wear. At 32 the manufatures figures out this pressure change in order to provide the best handling and traction for that model car.
More traction needed like a 1/4 mile run , remove some air , more speed for a track add a little extra a ir. For normal street driving follow the door pressure, in 1/2 an hour that pressure will be higher unless the tire is nitrogen filled.
Oh my god. Can you just get to the point in one short sentence please? Thank you.
Nitrogen expands as it is heated as well so the pressure will increase even with nitrogen
@motorbikemike65it does but the molecules are larger than air so it tends not to expand as much
Maybe your car was out of alignment or your corner too fast.
He failed to mention the car rides like a stagecoach now with 40 psi.
If you have false teeth and its winter time in our city, you will need a dentist as a friend, you will need him to fix the broken false teeth every time you hit a pot hole if you have 40 psi in a 15in tire.
Well my 05 relay didn't .it still road great
If you have pot holes, good luck with over inflated tires, you'll be blowing out sidewalls every 10 months
As opposed to smashed rims if you run them too low.😂
@sadwingsraging3044 Yeah and you can pinch the sidewall against the rim with lower pressure
Autocross racers watching this must be laughing
If your rotating your tires and not looking at tread wear , let someone else do it for you .
Yeah; let someone else who isn't paying for your tires tell you what shape your tires are in and trust them to be accurate and careful.
@robertrraineyjr967guess you didn't read and comprehend my comment.
Fast cornering will wear your outer tread down, like an eraser on a pencil. Just ride at or just above your door's placard, you'll be just fine. A little cush is good on the tush.
Not true. Over inflated will pop the middle and not the sides. Physics!
right on !
Years ago when radials first came out I was always careful to run them at 32 PSI. But they were always going lumpy with side wall separation. My tire man said I was having too much tire flex. So for many years I have been running all my tires at 42 PSI and I have great success. Also I never rotate my tires the normal chris cross way. After they are a little over 3/4 worn, I take the more worn tires from the front and move them straight to the back for the rest of their life. The advantages are, I get better fuel economy, better handling, and they last longer.
The criss cross method was for bias ply tires and thus became the wrong way for radials whis is simple . Rears to the front and fronts to the rear keeping the tires on the side they were . Every new car manual for 40+ years has stated this with a diagram .
What normal criss-cross way? This was changed 30 years ago to F to R rotation.
Actually newer cars have a different rotation than what you are saying, unless your tires have directional rotation arrows on them you take the front to the back and then cross the Rears to the front. If you don't believe me look it up
@lar7905Is this the same for front and rear wheel drive vehicles?
@thomasward4505Is this the same for front and rear wheel drive vehicles?
I run 256 psi on my Corolla and only need to gas up every 2,300 miles.
In Europe, the sticker shows optimum pressure numbers for normaly loaded car and seperate pressure for highly loaded car.
38psi has been perfect for my car.
You're obviously a communist trying to subvert our free society.
It didn't show 32 psi on the sticker. My car gives different recommended presures according to the load.
