    摘要: A pneumatic tire comprises a carcass (12), a tread (19) disposed radially outward of the carcass (12) and a crown reinforcing structure (14) interposed between the tread (19) and the carcass (12) in circumferential relation to the carcass (12). The crown reinforcing structure (14) includes a belt assembly having at least one belt ply (15, 16) with reinforcement cords extending parallel to one another and an overlay structure (18) including an aliphatic polyamide reinforced layer. The aliphatic polyamide reinforced layer makes an angle of between -5 degrees and +5 degrees with an equatorial plane (EP) of the tire (10), the aliphatic polyamide reinforced layer including aliphatic polyamide cords having a 1900/1 to 3000/1 Dtex, 1 to 10 turns per 2.54 cm cord construction.
