I just tore the sidewall on another MT/R-K and am going to switch tires. Any thoughts on what 40's work? I read a bunch of the threads and cant decide. I don't care about mileage on them but do drive on the road back and forth to my cabin every weekend in the summer. I care about toughness, and grip on the rocks. I was thinking Maxxis treps or trial grapplers but am open to any comments.
