I punctured my stock wheel and had to ride on a flat for two days. So it's time to put some better stuff on. Mainly used on hunts and local Fairbanks trails. A good mix of mud to rocks...hills to swamps. The clearance on the rotor and the stock 12 inch rims wasn't enough and a rock was wedged tight enough to put a hole in the rim. The dealer recommends a clutch kit if I jump up to an ITP 27 inch tire for a 14 inch rim to help with the weight and force of the bigger tire (yet another $300). Anyone have any good ideas?
