The basic rule is: the wider the tire the lower the friction. This is because a wider tire has a shorter bearing surface in the direction of movement. This in turn decreases the levelling of the tire, resulting in a tire that deforms less, stays „rounder“ and rolls easier, yet retains an excellent level of traction thanks to its wide bearing surface. A further increase in puncture protection is achieved as a result of the tire's huge volume: FAT FRANK offers much better protection from the dreaded „Snake Bite“ (grinding the tire against the rim of the wheel). Wide tires have even found a clever way of dealing with punctures: they „enclose“ sharp objects and „spit“ them out again after rolling off.
