Well, I'm running P265's on my 1990 Suburban 4x4 with the heavy Cummins up front. The reason why is because I bought a set of nice wheels that came with these tires. I figured that I would wear these tires out before installing new proper heavy duty tires. These tires definitely ride softer but handling is compromised. I have to compensate by driving around curves at a slower speed. However, most of our roads where I live in Texas are straight so it's not so much of an issue. That said, once these tires wear out, I'll be installing a set of 10 ply tires.
