Mud Tyres
Got a nice pair of Maxxis ADvantage in 2.0 they have a nice big volume, Kevlar bead and a chunky (typical Maxxis) self cleaning tread. They roll well too. Also a pair of Panarace XC Fire pro in 1.8 @ 450 gram, these roll really fast but have an agresive tread and bright red edges. Also a new pair of IRC Mibro (TNT) 1.95, ex-British team surplus stock-they use them, super fast rolling with ramped knobs, can be run at low pressures with the thicker side walls and still roll and clear well. pick of three really.
