Abstract
A pneumatic tire includes a radial ply carcass, a tread portion disposed radially outward of the carcass, and a crown reinforcing structure interposed between the tread portion and the carcass in circumferential relation to the carcass. The crown reinforcing structure includes a belt assembly having at least one belt ply with reinforcement cords extending parallel to one another and an overlay structure including a nylon reinforced layer extending transversely over the belt assembly and making an angle of between −5 degrees and +5 degrees with an equatorial plane of the tire. The nylon reinforced layer includes nylon cords having a 2000-2200/1 Dtex, 1-10 TPI construction with an end density of 10-35 EPI.
