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...
There is a thing called a load/inflation chart for every tire out there. Use it based on actual load and your ride will improve as well as your tire life.
