摘要： A tire comprises at least a left tread portion, a right tread portion, wherein the left tread portion and the right tread portion are axially separated by a longitudinally oriented groove. A tread reinforcement comprises a plurality of tread reinforcing layers wherein the reinforcement elements are formed of parallel reinforcements arranged in opposing layers, and each of the opposing layers has a bias angle relative to the circumferential direction. The bias angles of the reinforcement elements in each of the tread reinforcing layers corresponds to a plurality of equilibrium membrane shapes determined from membrane equilibrium equations that are joined together to create a continuous, complex shape.

摘要： In a tire 2, a band 16 has a jointless structure. A reinforcing layer 18 is layered over the band 16 from a radially outer side of the band 16. In the reinforcing layer 18, a reinforcing cord 40 is extended alternately on and between one end 32 portion of the band 16 and the other end 32 portion of the band 16, so as to extend in the circumferential direction. A direction in which the reinforcing cord 40 extends is tilted relative to the circumferential direction between one of ends 32 of the band 16 and the other of the ends 32 of the band 16. An absolute value of an angle of the reinforcing cord 40 relative to the circumferential direction is greater than or equal to 70°.
