Title:
タイヤトレッド用補強層
Document Type and Number:
Japanese Patent JP2007505781
Kind Code:
A
Abstract:
A tire has a radial carcass reinforcement surmounted radially on the outside by a crown reinforcement which includes at least two working plies and two meridian reinforcement plies. The axially innermost ends of the meridian reinforcement plies are spaced axially apart. Each meridian reinforcement ply has a plurality of reinforcing elements making an angle larger than 60° with the tire's circumferential direction. The crown reinforcement also includes a circumferential reinforcement whose reinforcing elements make an angle no greater than 10° with the tire's equatorial plane. The tensile rigidity of the circumferential reinforcement in the circumferential direction in areas thereof that are radially coincident with the meridian reinforcement plies is lower than the tensile rigidity of the circumferential reinforcement in areas thereof that are not so radially coincident.
