Re: PSI tire balance help. (queensny)
It depends on the tires. Some tires require different pressure. Go outside and have a look at the sidewall on your tires. I'm willing to bet they'll have a maximum of around 35 psi if they're the stock 185/60/R14 tires. I usually put mine to 32 or so, cause the pressure increases as they heat up on the road.

Re: PSI tire balance help. (Mr. S)
I am not close to my car, but i am riding on a set of YOKO's Y420's 185's. Thier natural look is very low, as in low in air. however the back ones look very fine. I know there is a weight differential but the look differential doesnt seem to measue up. very scary.. I will take your advice and look at the tires.. thanks MR. S... anyone else feel free to reply..

Re: PSI tire balance help. (queensny)
correct inflation pressure isn't determined by looking at the tyres, but by what the manufacturer of the vehicle recommends.
there should be a sticker on the door jamb, glove box lid or spare tyre well with the recommended pressures for front and rear.
if you have installed larger wheels with lower profile tyres, you will probably want to add 2-4 psi to the stock inflation pressures, depending on tyre size and speed ratings.
for example:
on my 1990 Civic Wagon, i have 195/55ZR14 tyres. the stock tyre was a 175/70R13. the stock inflation was 32F/32R. to increase (lift-off) oversteer, i run the rear tyres at a slightly higher pressure, 34 psi. the tyres themselves are rated for 44 psi. if i inflated them to the maximum pressure on the sidewall, the car would understeer like crazy, wear the tread centers badly, and ride like ****. when my wheels get back from the powdercoat shop, i will be going to a 195/50R15. i'll probably increase tyre pressures front and rear by another 2 psi.
other examples of different factory inflation pressures:
Jaguar XJ40 33/36
Mazda 626 (1986-1995) 32/26
Mazda MX-5 (1992-1998, 14" wheel) 26/26
for all of these vehicles, the factory tyre is capable of quite a bit higher inflation pressures than recommended. running them at those maximum pressures could cause many unwelcome results.
