    I'm new to this site,,, I just bought a set of Cooper STT tires for my 99 2500 Chevy. I'm using a Boss 8'6" straight blade. I started at 60 psi in the front and 55 psi in the rear,, truck is fairly stiff,,just wondering how soft I can run these tires without premature wear? Softened them to 55 psi in the front and 50 in the rear,, seamed to help the ride some,, still think I can soften them up a little yet but like I said I don't want to run them to soft and cup them or wear them prematurely,,, any advice would be greatly apperiated.

    I ran my cooper st at 80psi front and back all year round. I got 40K out of mine which is good for 3 years of plowing and hauling a trailer all summer. The truck drives better IMO.
