Was looking at a set of Nitto Ridge Grapplers and in the size I want, I have 2 choices. C or E rated tire meaning a 6-ply or a 10ply. I would guess a 6 for a better ride but most tires I have had were E rated. I don't tow much or off road much but was wanting input form you guys. These will be going on a 17" Method wheel.
