I rode with a random guy last weekend who was running a trials tire. He sweared up and down that they were 1000x better than any knobby he had ever used. We both ride the sane terrain. Lots of rocks, roots, and hard packed sand/mud when wet. I've read that trials tires really struggle in loose sand and mud but are great on roots and rock. However, this guy was also using the tubliss system, which he said he switched to at the sane time he started using trials tires. So I'm wondering if it is the tire or the tubliss that is making such great traction, or the combo of both. So what do are y'alls experiences with the trials tires? Worth a shot?
