Factory originally said 32lbs, but upped it to 35lbs because of rear tire center wear. Pressures are listed in the door jamb. I run 35lbs all around and scrapped the OEM tires for some Yokos. Tire wear has been good so far.
I run 35 psi up front and 38 in the rear. Always keep a digital tire pressure gauge in the car.
IMHO... check your tire pressure with the same gauge everytime. The difference between gauges can be substantial.
