Until now I went by the tire pressure that was on the sticker on my drivers side door. I think it was something like 35psi/front and 33psi/rear. I was just looking inside my owners manual and under the specifications, it says 30psi/front and 29psi/rear. I drive a 2000 Si with stock wheels and tires. How much psi do you put in your stock Si tires? I guess I'm gonna get my psi to what it says in the owners manual.:smoker:

Always Go with what the tire says. if you go with the owners manual then the specs might be different or they might be for different tires.

35psi and 33 psi as you had mentioned are correct
