The T31 replaces the very successful T30 EVO as the next evolution in Bridgestone's long line of sport-touring tyres. Silica Rich (Front Only) Silica Rich Compound provides enhanced gripping capability in wet conditions and low temperatures.. It also provides a more consistent and longer lasting grip. SILICA RICH EX (Rear Only) Performance in wet conditions is improved by increasing the amount of silica compared to conventional SILICA RICH. 3LC+CAP&BASE (Rear Only) The CAP&BASE construction divides the shoulder of the compound of the tyre into upper and lower sections. By using a high grip compound for the upper section of the shoulder, and a high stability abrasion resistant compound for the lower and central sections, this provides the desired combination of both performance and mileage. ULTIMAT EYE Visualization of the tyre contact patch behavior with measurement and simulation technology. Supplies less slip area for good traction while riding and improves wear life. MS•BELT MSB construction means that a continuous single strand is wrapped around the circumference of the tyre. This one-piece construction eliminates overlapping of belts, seams, and joints. An MSB tyre is lighter than conventional multi-cross belt construction, it also has more stability since it minimizes heat generation inside the tyre and gives high shock absorption HTSPC Bridgestone was the very first motorcycle tyre manufacturer to utilize 1X5 filament rubber insulated steel (MSB) in the manufacture of its motorcycle radial tyres. This makes the tyre more flexible, provides more stability without a reduction in shock absorption, and minimizes the generation of heat throughout the tyre. 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. The reduction in molecular friction also improves rolling resistance, therefore increasing fuel economy. Nanopro-Tech NanoPro-Tech is the name of a technology that facilitates the realization of the required features in a tyre by controlling the material microstructure through structural design at the molecular level. It is one of Bridgestone's fundamental technologies.
