Tire Pressure
"if"? Are you kidding? "if"?
This thread is an incredible embarrassment and should be deleted in its entirety. It is very disappointing to know that posts like the above were written by people with Evos; it is scary to know that they were written by people with driver's licenses.

That is max inflation for what the carcass can support before blowing the bead or zippering the sidewall.
32psi in the 245/40R18 will NOT damage the wheel or tire.

Agree with Iowa and FJF. This is a sad thread.

You are an idiot. And do not EVER tell anyone to do this.

I bought pretty pathetic tires with super soft sidewalls and keep them filled to around 38psi so they don't feel quite as bad. Still terrible though. Also keeps the TPMS low pressure warning from turning on when it's cold in the mornings

Correct psi is there for contact patch.
The max psi on a tire's sidewall designates exactly that, the maximum amount of pressure that tire can hold. An overinflated tire is stiff and unyielding and the size of its footprint in contact with the road is reduced. If a vehicle's tires are overinflated by 6 psi, they could be damaged more easily when running over potholes or debris in the road. Higher inflated tires cannot isolate road irregularities well, causing them to ride harsher.
I would suggest starting at Mitsu's recommendation listed in your owners manual/door jamb. From there you can tune up until you get the "feel" you're after. Do not exceed the tire's max psi.

32 psi as recommended by mitsu. I mean depending on the tire it could be higher or lower, but really, that's where you should start at. The 51 psi is max not to be exceeded, for example when the tires are getting installed and the tires aren't seated on the rim yet, they get overinflated and "pop" into place. Not even when trying to seat them you shouldn't go above 51 is what that means.
