I've ran this tire on tracks and off-road now and did not have a problem at all with the front end pushing. Even the back tire after an 1.5 hour GP is in great shape and hooked up great on everything from hardpack, grass to dusty track. I would recommend the SX1's as a combo, especially for the price you cannot go wrong. Folks saying it's out of round maybe didn't set the bead properly. I did have to put a decent amount of air in to set the bead, other than that no problems installing.
