Onstar recommends tire pressures to be 32 psi. How many of you have different pressures? I have 38 psi for all tires and wondered if that was too high. If so, what tire pressures do you have? Thanks.

38? Drop it to about 34 or even 33 and the ride will be much much smoother!!! Gas mileage will go down a little, but I think 38 is too much. Look on the inside of your driver side door.

Just put a set of Bridgestone Dueler H/L Alenzas, 285/60x18 on my 08 Tahoe. Lots of talk on B'stone's web site about how important proper inflation is, but no tire-specific info. They default to the recommendations that come with the truck, which seems to ignore the variety of possible sizes and profiles.

There is a full thread on this if you search. I seem to remember ZX saying that 32-34 was the correct pressure.
