MICHELIN have, for the first time, used PST technology in the production of a tire intended for use with a scooter. The continuous, fine capillary tread pattern breaks the surface tension of any layer of water, regardless of the condition of the rest of the tread. These have also been increased along the shoulder of the tyres, making cornering even more predictable, and consequently safer too. These 'Grip City' tires make sure you are better equipped to tackle wet roads, cobblestones and slippery road markings without discomfort! As proof of their superior performance these tires have already received worldwide manufacturers approval for use with over fifty separate models of scooters, among others, they are already standard on the PIAGGIO MP-3 three wheeler. A version of this tire (GT), specially developed for use with the Vespa GT is also available, to suit your individual and specific needs. SIP All-Weather tire type
