315 tire pressure

[O0oSKAMo0O]

im running 17 by 11's in the rear i was wondering what all you other guys with similar wheels run for tire pressures

[MEAN 98]

i run 32 psi

[AZ3.8Camaro]

Run at least 35 psi. I run 38 in my 275s for around town driving. Better mileage, better wear.

i find that 32psi is to high and its not wearing properly. the inside of tires are geting burned.

O0oSKAMo0O I would sugest what your max presure reads on the side of the tire, you should be running a couple pounds under that #. Hope that helps. ;)

if the inside of your tires are are getting burnt up it probably has to do with your alignment not your tire pressure. if it was your tire pressure both the inside and outside would be getting burnt or just the middle. if you haven't got an alignment since your tire upgrade i suggest to do that. hope this helps out

the wider the tire, the lower the pressure
the shorter the tire, the higher the pressure

I'd just start at OE 30psi and go from there, the optimal level might be 27-34, usually less in the rear is better however.

Try doing the water roll through test, make sure you're seeing an even pattern on the concrete and that its the same width as the tread exactly. If its not the same width and the sides are missing your pressure is too high, its too low when the middle is missing.

just to let you know mike auer there is no way to align the rear of the car it is solid axle there fore i cant adjust camber toe or caster its all tire pressure.and a bad alignment would not burn the center of the tires it would burn the outside

i find 27 to be the best Dominic your right

the wheel offset can also make a diffrence where your tire wears the most at optimal pressure

possibly an adjustable rear axle, cuz the rear may not be perfectly centered and 1 wheel may be more inside than the other.

[O0oSKAMo0O]

do you know how to center the rear axle

Adjustable PHR, and if you adjust it you must realign the front to it.

If you do any High Speed Driving, go 35 psi. Its right there on your doorjam. The lower profile the more air you need.
