Tyre Pressures

[xalfa]

What tyre pressures does everyone run on? Any recommendations?

The Saab manual recommends, the minimum, but what do you find the best for handling/comfort etc?

Wheel and tyre size?

Sorry, I didn't think it made a difference.

Thanks.

I'm on 225/45ZR17, I'm currently running those on 35psi. seems ok, but the ride may be a little harsh, found 32psi was too low...

Im on 215/45/17's and run them at 30psi :)

My personal preference is 32psi on tires rated 40 psi max.

Expansion on a hot day will raise the 32psi to about 35 psi+
due to heat expansion.

Never set the tires at the mfg. max rating. Great way to ruin the tire surface and blow a sidewall.

I talked to the owner of the performance shop and
He said best is 10 psi under the max psi..when it's cold..
I put 40 psi..max is 52 psi..
Usually when the tires get hot, it goes up about 4-6 psi.. :P
