STOP over inflating your tires!

1. Those tire pressures are recommendations – not rules or laws.
   If a person wants a smoother ride – lower the pressure.
   A tighter ride or for handling raise the pressure.

   How do your tires wear with your style of driving.
   Adjust your tire pressure so the tires wear evenly with your driving habits.

   In town mostly?
   Raise the pressure so the sides don't wear as bad.

   I have found that higher tire pressures give us an even wear pattern – when we replace tires they are evenly worn all the way across.
   On the Kia Soul my wife drives we run 40 psi 100% of the time.

2. I never new this till today. I always inflated my tires to what it said on the tire but today I learned. My question is if I deflate my tires to the correct pressure from max will my tire be ok. Brand new tires on it. I caught a nail and plugged it and realized none of my other tire had the psi of what the tire said on it. I max psi it for before I knew and drove on it for 1 mile and then researched it. I hope I didn’t damage my tire more then that nail already did 🤦🏻‍♂️

3. It said 35 (cold). How much pressure difference does it make if its a hot tyre? Like if i drove around all day and i wanna fell my tires after that..?

4. have been gigling the whole time (don't understand these over pressure idiöts myself)

5. All good until someone changes rims and tires to non standard, I watch tire wear and adjust as needed

6. You are WRONG ! Only inflate the tires to the door sticker if the car has factory sized tires. The Junkstang has low profile tires that need 40 to 50 PSI. .

7. I strongly disagree with this policy. Let me cite the Ford explorer issue of 20 years ago. The rated air pressure on the door is 26 psi. Ford did this to give it a smoother ride. Trouble was running on under inflated tires caused a lot of rollovers. Wears out the shoulders of the tires. And lowers MPG. I have a 2001 explorer and I run my tires at 34 psi. I have no stability problems, the ride is comfortable and I get a couple of more mpg's than running at 26 psi. Plus a longer tire life.

8. EXCEPT! That inflation tag is for stock tires of the time period of the car. The older the car, or the more radical the custom tire, the less relevant is the factory tire pressure spec. That 'stang, for instance, isn't close to stock and is probably around 20 years old. The data tag has zero relevance to the shoes it is currently running. On older vehicles, or non-stock packages, the tire maker is the source because their tires are designed for certain pressure ranges. I mean, really, imagine running 24psi in your modern low-profile radial…

9. My jeep doesn't have a sticker in it. Should I go by the tire?

10. My Charger lists 30 psi but I typically keep 32 in them. Every single time I get it back from an oil change or tire service I have to adjust the pressure because they always fill them to 36-38 psi cold and sometimes I've seen up to 42. This last time I complained to the tire shop and he said they set them 2-3 psi higher for our altitude, so I asked him to explain the math to me when the car lists 30 pounds and they inflated to 38. Too many morons in the service industry.

11. ok… my stock FJ's 16s say 35.(door panel) My 295/70/17 terra grapplers call for 55 cold. I run about 42 empty because thats where the tread rides correctly. So as much as I really like your show, I'm calling bull$#!t on the door stickers. Ive had to scratch out the door pressure and add an "ask me". Because 35psi is enough to kill someone when you hit a rut on underinflated tires.

12. The other thing to do is, assuming you're not using the OEM tires for your car, check the treadwear after you've been running them for a season or so. If it's more worn in the middle than on the edges, it's over-inflated and could go down a couple PSI, and vice-versa. Start with the pressures on the door, but different tires sometimes like slightly different pressures, so this helps you fine-tune.

13. Had a customer who could not understand why the light stayed on after he filled the front tires. Both rears were 10psi UNDER while both fronts were at 90psi.

14. uh, no, not when I have 10 ply tires on my truck and need 80 psi to tow my trailer., the door says 35 psi, and Walmart put 35 psi in brand new 10 ply tires, I did not check and when I hit the higghway thhe triler wobbled.

15. That’s interesting I didn’t know that. I have always heard to run max tire pressure due to less rolling resistance and better fuel economy and to prevent uneven tire wear keep them rotated

16. 50 psi on a stang which has a tendency to do a dance and crash when leaving car shows explains alot.

17. This only works if you have the stock tires that the vehicle comes with. It even says what size the tire is on the sticker. If the tires have been changed from factory, then the sticker is useless. And the majority of vehicles on the road have aftermarket tires on them after 60,000 miles. The best option is to call the tire manufacturer of the tire that is on the vehicle and they will give you their recommended specs. The sticker is not always the best option for the vehicle as proven by ford, firestone and the explorer roll overs and blow outs. Ford called for 32 psi, and the tire was not rated to go that low on that weight of a vehicle which caused major blow outs and roll overs. Also to note that if you go to an e rated tire on a 3/4 ton truck in the off road sizes, they will not allow a max tire pressure over 65 psi and those trucks sticker says 80 for the rear. So the sticker needs to be changed to match the tire that is installed.

18. PSI specs at the door is child's play. Our 2017 Hyundai Tucson had a new set of tires installed, and thanks to Michigan's climate (we feel all 4 weather seasons), the tire pressure varies. For our safety's sake, if I had to inflate our tires, I'd be giving all 4 tires and our Spare tire the maximum 40.0 PSI in it, or put in Nitrogen for the tires.

19. 1. Everything that "First Last" said in his comment. That said: what do you expect from people in a country that hands out driver's licences for 25 bucks and not thousands of dollars with many months of training? the door sticker, at least on older cars, shows an outdated value…you usually go 0,2bar above that (whatever that is in psi)…of course, depending on road condition……slippery roads etc… and you SHOULD put more pressure in it when you load your car to the limits, whether that's luggage or people….as important as not overinflating is not to underinflate which might be a little more dangerous due the overheating and instability of the tire and handling (we disregard the fuel waste for a minute and focus on a possible tire burst). Then, people should also be aware / get educated on how to read the production date of a tire….and the recommendation period for a tire change even if the thread is still very good (it actually is 6-7 years even if the tire might last another 10 years not parked in the sun all day)….smooth surface on a long drive with higher pressure, great for fuel consumption unless it wears out the middle part of your surface significantly more than towards the sides…that would make it more costly in the long run (because new tires needed)…lowered stiff suspension and bad streets with too hard tires, not good. underinflated tires for driving or just sitting parked , not good and potentially damaging which you often can't see from the outside of a tire. One more thing: don't pressure- wash your tires from a close distance. It can destroy the fibre of the side wall on the inside, you will not necessarily see it anything on the outside….

20. Rainman Ray — Great videos and content except for this one .. Sorry bud – but – Wrong , and your gonna get somebody hurt with that advice . Seriously !! . Door stickers are only for that specific factory size. Changing it to something else will require different air pressure and im betting you already know this… I have 3 vehicles with aftermarket wheels and tires… The best rule of thumb I have discovered over the years to get the best tire wear comfort combo is to read the max tire inflation and on cars back it down (COOL TIRE TEMP ) 1/2 lb for every ten the tire calls for and 1 lb for every 10 on light duty truck .. This will vary obviously from tire to tire and one vehicle and the next and needs refining but this is the basis to start with NOT the door sticker numbers unless you are running factory wheels and tires or some very close to what came on the car … Think about that Ray.. Otherwise good job on the videos.. Nice work

21. I use to work with a guy that would do the same thing you said not to. I told him the same thing he would never listen to me. Use to piss me off to no end. Once a week I had to deflate the tires so glad i don't work with that dumbass anymore.

22. The amount of time I have run into over inflated tires is mind boggling and scary at that.

23. Learn something new everyday. Hmmmm

24. Had a guy come in yesterday because he thought his tires were low….sticker called for 36 psi, he had 50psi+ in all of them.

25. Idiots at oil change fill tires without looking at PSI

26. Lol, I made that mistake when I was a teenager.

27. Too many numbers!!! I’ll just wait til it explodes 💀😭🥴

28. Don't stress too much on that number either. Not only will the pressure change a little with temperature, but tire gauges themselves will vary a couple degrees here and there. Ballpark is just fine. I've had customers complain because their dash says the tire pressures are off by a couple degrees, then show them my pneumatic gauge that shows they're dead on because that's what I used, then get an old school spring loaded gauge to show them it's also off by a couple PSI and try to explain to them how real life works. lol

29. Running higher psi than what is on the door sticker is perfectly valid, Toyota Prius front tires are a perfect example of requiring higher psi than what the door sticker says.

30. @Rainman Ray's Repairs how about this; your car door says " for tires that are 205/50/17 you should have 2,3bar" <– but you actually have "275/30/19" tires on you, therefore you dont know what your car wants the tire pressure to be, right? So my question is: do you just wing it?

31. I've been doing the same always because I thought that the pressure rate is for that tire specifically and what is on the sticker in the car is only for the original tires it came with so if I put on any other new tire I should follow what the tire says because that pressure is for that tire and thus that tire will perform at it's best with the pressure written on it.
    I guess then no matter what tire I put on, I should always follow the car's pressure guide.

32. I feel sorry for the folks that don’t know this information.

33. I usually go about 6 or 8 under because my cars don’t have door tags

34. The guiltiest offenders are tire shops. I can’t tell you how many cars we get with new tires that are severely over inflated.

    Saddest part is most drivers don’t even notice.

35. Thanks for this lesson. The pressure on the tire also says Max Pressure cold. The tire can take more pressure than the car maker wants you to put in. This is in case you are fully loaded and the tire needs more air. When you drive, it also heats up and the pressure goes up as well. So do as our man Ray says and look at the placard on the door to properly inflate your tire. Over inflate and then hit a large pothole and you will be buying a new tire and maybe rim.

36. Not to mention if you put in the max according to the tire the second that tire gets hot your over.

37. Don't forget that is also for when the tire is under its maximum load capacity.

38. I kept em around 80 on my 2500hd cuz I thought they towed better 65 changed my life.
