    Re: Wagon Rear Tire pressure?

    I'm running 37 rear, 34 front. Tires are wearing evenly, rears have more wear than the front (no shocker there). I have ~17K on them now, and the rears look like they may hit 20K. Maybe. Fronts might make it a little longer. I'll be going to PSS's when the time comes.

    One thing I've noticed is that on both my iPhone app, and the monthly OnStar emails, the rear pressure recommendations have changed to 32 psi all the way around, same as the Coupe & Sedan. Not sure if GM really changed the specs, or if it's an error with OnStar???

    Re: Wagon Rear Tire pressure?

    I run all my car and bike tires at two pounds over recommended. Sidewall flex causes heat, heat kills tires. Max pressure on the sidewall (PS2) is 51 psi, so I'm well within limits even after the tire heats a bit, and goes up another pound or two...
