I ride every weekend, from tracks, to desert to sand and occasional mud. I am your typical weekend (every weekend) warrior, but since I am not a sponsored rider I have to find a good value in tires since I burn thru them quickly. I have tried dunlap, maxxis, michellin, sedona, and a few others. I tried the Artrax because they were cheap, but fell in love with them because they last longer than all the others I have tried and out perform them as well. I get about 4 or 5 MORE rides on these than the other brands. My typical terrian on a given weekend takes me through very rocky trails, sand and then washes which are typically a combination of gravel and sand with occasional sharp edged rocks and boulders. I have never had any issues with traction or durability with these tires so if you haven't tried them yet get a set and enjoy the best value and tire on the market.....BUT make sure you leave some for me!
