Factory Wheel Air Pressure

[wurgs]

I am looking to pick up some LT tires and was wondering what the max air pressure my factory rims can take. I have an 09 GMC All Terrain with the 18" wheels. I'm going to run about 50-55 psi when towing my camper and probably go down to 45-50 depending on how it rides when day to day driving. Any help or search links appreciated.

99% of the time the rims can handle more than the tires for pickups

Your tires will fail because of excess pressure LONG before a cast aluminum wheel will. Nothing to worry about.
