Are you asking about the ones that have a "chevron" style center tread design (one chevron points in, the next out, repeat....? If so, I am currently running a set of these from Wally-world ( they call them the Super Sport ). I go over to the Red River Gorge at least 3-4 times a week, and I go any where that I please! There are about 10 of us that ride on the 3rd sunday of each month, and everyone seems surprised that a tire this "mild" can keep up with everyone. The only mudholes that I have trouble with are the REALLY deep ones, which usually give everyone trouble any way. Oh, now that I think about it, I think the Big "O" version is the Bigfoot MT. They are reasonably quiet on the interstate (you can actually have a normal conversation with out having to raise your voice.), and seem to returning good wear so far.
