Luftreifen mit Gürtelbandage

摘要

A pneumatic tire (10) comprises a radial ply (12) carcass, a tread portion disposed radially outwardly of the crown area (14) of the carcass and a crown reinforcing structure interposed between the tread portion (19) and the carcass. The crown reinforcing structure includes a belt assembly (15) having at least a first (16), radially innermost and a second (17), radially outermost belt ply as well as a textile overlay structure (18) which is superimposed radially outwardly to said belt assembly (15). The textile overlay structure is reinforced with cords (20) being made of materials including nylon and aramid. At initial elongation of the cords (20), the primary load bearing yarns are the nylon yarns; after appreciable elongation the primary load bearing yarns are the aramid yarns.
