On my half ton truck referenced above, I use the vehicle manufacturer recommendations when unloaded, with one change. The recommendations on a pickup assume a load in the bed, so I run less air in the rear tires. The door jamb sticker on my truck recommends 35 psi in all four tires. When I am unloaded, I run 35 in the front and 30 in the rear. I am completely satisfied with the ride quality and tire wear.
When I get ready to pull a trailer, I pump them up to 55 in the front and 65 in the rear.
These tires are LT245/70R17 Firestone Transforce on a 2007 Chevy Silverado Classic half ton crew cab.
