Is there much of a difference between a radial swamper and the tsl?? Some people say the radials last longer others say they dont but they ride better. Someone today told me that the tsl's are fine if you dont live in cold wether! I guess when its cold they take a while to warm up and smooth out the ride. I have Mickey Thompson baja belted, which one of these will be close to that? Is the radial worth the extra $$. Do they really last that much longer??
