Correct Tire Pressure

oscar1204 · March 27th, 2011, 03:13 PM

ok heres the thing
i know that on most cars the recommended tire pressure is 32-35 psi
but what if you have wider tires?
would the pressure change?

example

on my mustang i have 315/35-17 rear and 275/40-17 front

It doesn't matter. PSI doesn't change for bigger tires. It is pounds per square inch. A 315 will obviously take more air then a 215, but the measurement of PSI is the same.

So stick with 35 psi. I like 38 front and 36 rear.

haha.. My buddy was cruising at the local cruise place on the weekends and thought lowering his b18's tire pressure down would allow him to beat up on a Cobra. I think we can all agree on who won there
