Anyone have any experience with these tires?? A local guy has a set for sale at a reasonable price. $500 mounted on american racing alum. rims. tires have about 80% tread left. Im not sure how these tires will do in the mud though. the tread doesnt look to aggresive, its more of a linear tread, not knobby, but the corners of the tire and the sides are real knobby. These are a few years old, and the tread has changed a little bit from the new ones. The rims are mint and come with center caps and lug nuts. I mostly do trail riding and encounter a few mud pits on the way. Do you think i will regret buying these? or will they do fine in the mud? I think that when aired down, they would perform decently, but looking for some input from someone with experience with them.
