im running 215/60-15 up front and 255/60-15 on the rear. im concerned about my rear tires wearing out in the center prematurely, which has happened to me befire with another car, and the tires that came off were the same way too. i think the tire might be too wide for the rim, but i dont think it would be. stock size rims, just aluminum. im running 30 psi now in the rear tires, and 38 up front. i left a patch of rubber at school, and it seems like there is only about 4-5 inches of tire making contact on the ground.

 

run them at 35 when you burn out tire elongates hense the reason for the narrow patch

 

The 255s need at least an 8" rim, 9" would be better. The narrow rim is going to force the center out and make it wear out faster. Excessive pressure will just make it worse, low pressure to correct the problem will make for bad handling. The only tires that stretch safely at high speed are drag racing slicks, because they are especiallly constructed to do it. If you street tires are doing that, you are spinning them too fast and will soon blow out.

 

what size would the stock rims be?

 

They came in various sizes, depending on options. The rim size is usually marked on the rim.

 

ive got aftermarket rims on my car, and they are aluminum. i dont think there are any marks on them at all. i think i will look back in a newspaper where i saw a set of race tires and rims for a second gen for $80

 

ive got it down to where i feel is good. 30 psi in the rear and 38 in the front
