I have been looking at the Interco swamp lite, ITP mud lite xtr, and GBC dirt tamers. I haven't herd any feedback on the swamp lite tires, I'm going with the 26" tires. I ride on rocky sand (greasy when wet) primarily but I plow snow in the winter. I'm concerned with the life of the tire the most, I don't want to be buying tires every year which is what the stock tires are lasting.
