I am not running stock wheels and I have found that 60psi is the right amount when I haul the trailer. We now have about 20,000 miles logged with the pickup and trailer and everything has been outstanding. When I am not hauling, I run them at 42psi. Tire wear is a little faster than top-shelf, high-dollar tires, but I am pleased so far. My actual, legitimate complaint is braking performance with the increased size of the 34" tires. But the Crosswinds on the Ram 1500, ML250 and the camper have exceeded my expectations in a very positive way. .......
