Hey guys, I was wondering that if your air p.s.i. is too high can that make a tire explode. Haha, ok, maybe not explode but ruin a perfectly good tire. I have the o.e. Michelin's on my Accord. I run the p.s.i. around 40 but the side of the tire reads that 44 is the max. But what if I exceed that? What if I go to 46, 48, or even 50 p.s.i? Thanks

there are other issues that could happen, as has been documented many times in the past....

most common: uneven tire wear....

Correct!! Center wear will be premature on over inflated tire.

And even if you run the pressure higher for a limited period of time (say when you're hauling a heavy load), you run the risk of a failure due to stressing the sidewalls or bead areas of the tire. Maximum pressure ratings are there to account for increased pressure once the tire is warm - and that increased pressure along with the stress the tire might be under has now gone past where the tire manufacturer would honor any claim.

For the long term, the tire wear situation is the biggest issue, as I1 and Stiller have identified....

Some folks run a higher pressure than what's recommended for the vehicle (but not higher than the max listed on the sidewall). They claim better fuel economy without sacrificing tire wear. I don't think I've ever heard anyone recommend running a higher pressure than the rated "max" on the tire.

I've regularly run 2-3 psi higher than what the manufacturer recommends without any noticeble reduction in expected tire life.

It's common with the hypermilers but I don't buy into it.
Like WisAccord I run mine 3psi over for better handling and to retain an acceptable ride.

Just wanted to throw in some clarity to what everybody is saying....

2-3 PSI HIGHER THAN DOOR JAMB STICKER(Car manufacturer rating)...

"NEVER " higher than tire manufacturers PSI rating on tire.

I1;)

Good point there, that could have easily been misunderstood.

I seem to remember a series of posts from Xcel on the tire pressure subject where he was noting running at the sidewall max pressure or higher and given the construction of new tires their not wearing odd as a result.....Ring any bells?

The sidewall does say 44 psi max (cold) on my 16" Michelin's. There's no reason why you couldn't run that, you'd just loose a lot of rebound in them.

I run mine a little higher than the door jamb recommendation so that the tires wear more evenly. The door jamb says 30/32 and I usually run them at 35 all around. I noticed the outside edges were wearing more than the center when the tires were inflated to Honda's recommendation.

The tire pressure max that is listed on the sidewall is what the manufacturer is saying what the tire has been tested for. Yes, you can go higher, but it was not tested under that condition.

Some risks of inflating a tire beyond the max indicated by the manufacturer include: premature/uneven tire wear, rougher ride and damage to wheels/rims (tires won't absorb bumps as much).

If you do have a problem with the wear, you probably won't be able to get any kind of warranty coverage if they find out you exceeded the max air pressure.

Running 40psi is fine on the OEM tires.

Seems to me like he runs them at 50psi. Even 40psi is bone jarring for me, I'll stick with 35 front 33 rear.

I ran nitrogen, in my tires, about a year ago. I noticed very little but a slight gain in gas mileage. They put the pressure up to 40 all around and I have noticed that the outer edges wearing out faster that the middle.
About a month ago, I was driving after it rained. I had about 38-40 p.s.i. and my tires did awful! So I have noticed that if you go threw rain, snow, or even wet roads put your air pressure down! When it is March I am going to get my tires filled with nitrogen again. I want to wait for the very slim chances of snow to pass, for Arkansas.

Yes, that max pressure is when the tire is at its max rated load, so on a light load that's even less reason to worry about the max pressure.

I've run 80psi with no issues. Ok, so it was an accident, but I drove around like that for a while (on an older car).

The only side effect is sidewall distortion. The tread seemed unaffected and the handling was awesome.

In my accord i typically run no more than 40 psi front (less in rear), and see no real advantage of running more.

Max 44PSI Cold probably equals something around 50psi hot, so if it were my car, I wouldn't worry if you accidentally put in a tad too much and then correct it.

The only issue of high air pressure is that on wet roads they where as slick as a politician! As I was going around curves, and not even close to high speeds, my tires would almost start to skid but then regain control. I pulled over and they all read 40 p.s.i. So I let some air out, 32 front 30 rear, and could nitice a big difference!
