Abstract: A pneumatic tire has a belt ply buried in a tread portion and a carcass ply running into an inner peripheral side of an end portion of the belt ply from a pair of bead portions. The carcass ply was divided in a tire width direction at the tread portion. A division width of the carcass ply is equal to or more than 35% of a maximum width of the belt ply. An auxiliary ply formed by reinforcement cords extending at an angle within a range of ±20 degrees with respect to the tire width direction is arranged in such a manner as to overlap with the carcass ply in an inner peripheral side of the end portion of the belt ply and extend out to an inner side in the tire width direction than the division end portion of the carcass ply.
Abstract translation: 充气轮胎具有埋设在胎面部中的带束帘布层和从一对胎圈部延伸到带束帘布层的端部的内周侧的胎体帘布层。 胎体帘布层在胎面部分沿轮胎宽度方向分割。 胎体帘布层的分割宽度等于或大于带束层的最大宽度的35％。 以相对于轮胎宽度方向以±20度的范围内的角度延伸的加强帘线形成的辅助帘布层布置成在带的端部的内周侧与胎体帘布层重叠 并且延伸到轮胎宽度方向上比胎体帘布层的分割端部更靠内侧。

Abstract: In a pneumatic tire are defined: a first imaginary line VL1 passing through a ground contact surface in a meridian cross section of a tread portion, a second imaginary line VL2 passing through a bottom portion of a shoulder main groove and parallel to VL1, an intersection point between VL2 and a surface of a shoulder land portion outward of a ground contact edge T in a lateral direction, and an equatorial plane CL. Given A as a distance in the lateral direction between an intersection point P and CL, B as a groove depth of the shoulder main groove, and C as a distance in the lateral direction between T and CL, 0.80≤(B+C)/A≤1.15 is satisfied and, given E as a distance in the lateral direction between the bottom portion of the shoulder main groove and P, 2.0≤E/B≤5.0 is satisfied.

Abstract: A tire with radial carcass reinforcement comprises a crown reinforcement including a layer of circumferential reinforcing elements distributed axially at a variable pitch. The layer of circumferential reinforcing elements is radially crowned by a tread strip, which is connected to two beads by two sidewalls. The layer of circumferential reinforcing elements comprises five parts, including a central part, two intermediate parts and two axially outer parts. The value of the pitch in the two intermediate parts is less than a value of the pitch in the two axially outer parts. Each axially outer part is axially separated from the central part by a corresponding intermediate part. The value of the pitch in each intermediate part is less than a value of the pitch in the central part, and the value of the pitch in each axially outer part is less than the value of the pitch in the central part.
