Time to put a new set of tires on my 2007 GMC 2500HD. When I bought the used truck it came with 10 ply load range Ds on it. (LT 245 75 R16) I have to run these tires at 50 PSI or else when I am drivin...
I keep my rear tires aired down on my '09 2500. If I run the recommended 70 psi in them they wear down in the center way too fast and at $250+ each...ouch!
I run them 58-60 psi unless I have to haul something, then I air them up.
