The reduction in molecular friction also improves rolling resistance, therefore increasing fuel economy. Tire Specifications:Load / speed index: 56H.Construction: Bias. Scooter tire for the maxi-scooter rider who doesn't let a little rain slow them down. Ride confidently and in style on this versatile tread pattern that is derived from the Battlax Sport Touring T31. NanoPro-Tech NanoPro-Tech is the name of a technology that facilitates the realization of the required features in a tire by controlling the material microstructure through structural design at the molecular level. It is one of Bridgestone's fundamental technologies. RC Polymer RC Polymer technology optimizes the distribution of silica within the rubber compound and improves tread flexibility allowing greater contact with the road surface in both hot and cold conditions.
