Pro Comp tire pressure?
 

I just got a set of pro copmp Extreme AT 33/12.50- 17 and im trying to figure out what pressure to run in them.....They are an E rated tire with a max 3195lbs at 65 psi. My truck is an 03 2500 HO Quad Cab short bed with a weight of 7750 empty. I cant find a phone number to call Pro Comp. Any help would be greatly appreciated.

For the best milage and tire wear, I would run the pressure that is on the tire

DO you mean the max pressure of 65psi?

The pressure on the tire is what is recommended by the manufacturer. I run 65 up front because of the weight and 60 in the rear unless I am towing and then I bring it up to 65. I run about 12 PSI in the sand.

Yea, The Manufacturers recomend the pressure for a reason, it's what they determine what it takes to keep the side walls from flexing too much and keep as much tread on the road. I't ok to run less pressure when running offroad, but for highway driving, IMO I would run the recomended pressure for better tire wear.
