What is your stock tire pressure?

[Yarus Maximus]

My stock Toyota tires are set to the recommended 32 psi. Is yours at a different pressure? How much and why?

[djct_watt]

41psi. . .

. . . because of prolonged speeds over 130kph, mileage, and tire longevity (I always wear out the outsides of the tire first and over-inflation gives we even wear).

[127.0.0.1]

40

little more mpg

little less wallow

I have used 40 psi x 4 on all my vehicles since 1982. it is just what I do has nothing
to do with vehicle type or use.

I will deflate for sand and special circumstances

[Yarus Maximus]

At 40 psi my dashboard rattled when driving over bumps. Have you experienced more noise at that pressure?

[marcus]

42psi on stock tires.

No rattles, except some from the hatch that have always been there.

[2007yariz]

Yaris sedan here, i try to keep it at 35psi.

But my door jam says 32 psi on all four tires...

[TwoBearWisconsin]

40 psi on all four for me.

[fearturtle44]

I keep mine at 32-33. Stock tires lasted 40,000 and now have a 60,000 tire which I am also keeping at 32-33. Got nitrogen this time. Might be a waste but wanted to try.

[Yaris Hilton]

44 PSI. I've run all my tires at max sidewall pressure as long as I've driven.

[kimona]

At 40+ PSI, my car bouces all over the road like a basketball!

That's the secret to uber gas mileage. Get the car bouncing, shut off the engine, and watch her bounce down the road, gas free.

[Vang]

35psi

[eTiMaGo]

35psi... I tried 40+ on my old 18" wheels, it really made it a lot more harsh and not a noticeable mileage improvement. Might try it again on these 15" wheels after a couple more tanks...

[BailOut]

I run 60 PSI year round for both lower rolling resistance and much stiffer performance in the switchbacks in the mountains here.

Folks on this forum go ape shit every time I bring this up so be prepared for a thread derailment, but the only things I'll say are that I've never had a problem with this, it brought greater longevity to my tires, and I've even avoided becoming the 4th car in a 3 car accident thanks to my preparedness and alertness as well as the car's agile handling, even at 60 PSI. I even had a big puncture from a gnarly piece of metal I picked up and it didn't act any differently than blowing a tire at 35 PSI.

It just works, so get over it.

[KrazyDawg]

Max side well of 44 PSI. Higher tire pressure is safer than lower tire pressure. You have an increased chance of having a blow out with a lower tire pressure. Lower rolling resistance and increased longevity are the result of a higher tire pressure. When you adapt your driving for DFCO, it makes you more aware of the road ahead.

Note: For every 10 degree change in temperature in Farenheit, it's 2 PSI.

[centrysis]

:smile: my tires arent stock but I keep mine at the max pressure of 44 psi.i'm running 215/35/18's though

[R2D2]

I run mine at 60 psi as well. Might be a tad more road noise but the car rolls freely and handles great.

whats the max pressure on your tire.i've always ran a higher tire pressure but never over the max.i heard its not good.

[STC]

42 psi Summer and Winter...

Longevity, wear, and lower tire resistance!

Cheers! :smile:

[goliath1812]

40 psi on all 4, pretty much all the time.

[bronsin]

How many psi does it take to make a tire explode? I dont mean running it so it heats up and goes bang. I mean blowing it up like a balloon and POW!

It would take more pressure tan any pump I know of can deliver. Think about when your tire hits a pothole, or even better a pavement drop. The g-force is enough to increase the PSI exponentially and rapidly, but tire blowouts are rare.

In general, this is true. Over-inflation increases your odds of a blowout when encountering rough terrain or a pothole. But an under-inflated tire is just as bad if not worse.

However, if you have damage to your tires, especially to the sidewall in the form of heavy curb damage, your tires will be significantly weaker, leaving the possibility of pop while pumping.

Some people have probably seen this link before. It's an article about officers using tire pressures rated for max sidewell.

Over inflating does not give you even wear.

Yeah, I agree with everything the article says. But it does not mention damaged tires. If a tire is already damaged, high PSI will stress those damage points, but you shouldn't be driving around on a damaged on sidewall anyway. But hey, I could be wrong as it is just based on my experience.

[djct_watt]

Well, if you are heavy in your cornering, you will get heavy sidewall deflection (especially in a 60 series tire), thus wearing out the corners faster. Over-inflation minimizes this and CAN (in some instances) result in more even tire wear.

[Hershey]

35 > 36 p.s.i.. Tried higher and it was choppier and felt those lousy roads / streets more and hear more rattles spring up . Few years ago we test drove a new '06 XB and it road like a brick on wheels :eek: . Could of used a styrofoam donut . Went back again to check tire pressure of the same XB and they were at 40+ p.s.i.. Let air out of each tire to about 35 p.s.i. and road much better . Ahhhhh relief :smile: . All in preference .

Their tires are most likely V, W, Y or Z rated, because they're concerned about high speeds, not long coasting.

[djct_watt]

^ back in 2002 I used to buy used CHP tires from the CHP training facility in Sacramento. They ran 205/65/R15 V rated pirelli's. It was awesome because they still had half their life on them and ran leas than a 1/4 of the price.

[SilverBack]

40 PSI at first to save a buck on gas, but I'll lower it to 38 or 36 when I notice the center section of the tread wearing down a little faster than the rest.

[Thai_Dang]

i bought mines new, and it came from the dealership pumped to 44 psi for the 15''. i didn't even know they can be pumped up to 60.

[fluke_boy]

When I first got mine from the dealer I noticed the low tire pressure light was on. I pulled over and scanned the owners manual and found out what the low tire pressure light meant as I had no idea at first. Pumped it up to 32 and it has stayed that way ever since. I guess I'll try 35 - 36 for the 15" when I next gas up.

[detroiter]

You guys running 60 psi must have roads from the Kingdom of Heaven or something. No way possible you would survive Michigan roads with that setting.

I was running 44 psi and now I'm at 33 psi. The ride is much more comfortable and
much, much smoother. The bumps are alot less jarring as well.

38F and 34R. Thats what give me the best feel.

Wow, with that attitude, you must be the bell of the ball. . . ever try making a point and use arguments or is that beyond your comprehension?

Here's some PHOTO evidence for you smart guy. . .

Better yet, take your car to an autocross and bring some paint with you. Paint a white line across your sidewall and over your tread and drive. Now try adjusting your tire pressure. You'll notice that with higher pressure, less of the white line on the sidewall gets rubbed off. Tire pressure is real, and waving around a BS flag at other people rather than arguing, no wonder you have no idea about it.
