what tire pressure do you recommend?
I have the GT AWD curb weight is about 3,780 lbs
the door sticker says 35 psi

I took it in to the dealer for a checkup, the techician put down on the paperwork the tires are checked and set at 32 psi now.

Is it ok to deviate a few PSI from the sticker on the door?

 

Stock size rims and tires?

 

Yes, I think it is 225/55/18
I went home and check at noon it reads about 37 Psi all around.

 

your psi will fluctuate as your tires heat up / cool down. a few pounds one way or the other won't hurt. I usually keep mine at 36 lbs.

 

Good advice. Just try to keep it close.

 

I have been told by my local performance tire shop that they inflate their tires they mount to 10% below that max pressure rating on the sidewall of the tire when cold, not by the "comfort" rating in the doorjam. Seems to work for me just fine and the outer edges of the tires don't wear as quickly.

 

That's probably about 40 PSI+
I would think you sacrifice some traction and a harsh ride that way. But you will get a little better gas mileage. It might also be an advice given to sports cars because they have low profile tires (45 aspect ratio or less) and overinflating will reduce chances of bending a rim.

I wonder what happens when you inflat the tire to 10% less than maximum at sea level
and take it to 9000 ft mountain summit, would the tire be very overinflated then?

 

Here in the desert the roads are good and almost always dry, so traction really isn't an issue so to speak. Sure the ride is a little more stiff. But not a big deal to me. Haven't really checked the pressure from low elevation to a higher elevation. Maybe next time I head to the higher elevations I'll check.

I've been inflating my stock Goodyears between 40-41psi.
