I have some Carlisle Turf Tamers that i have on the rear of my R. I still have the stock tires on the front. Carlisle doesnt make a 21-22" tire that would work for the front. I like the way the 18" T.T. handle and my question is.....does anyone know of a brand/ tire similer lug pattern that would be compatible with the rear?http://www.titantirestore.com/turf-tamer-atv-tires.html
