摘要： A pneumatic tire has two circumferential-direction main grooves (13) and lug grooves (15). The circumferential-direction main grooves are disposed outside quarter point sections of a tread contact width (TW) in a tread width direction, respectively, the two circumferential-direction main grooves extending in a tire circumferential direction, each of the quarter point sections of the tread contact width (TW) being a midpoint between a tire equator line and a corresponding tread end portion. The lug grooves are extended outwardly from the circumferential-direction main grooves in the tread width direction. Each quarter point section of the tread contact width (TW) has a rib-like shape continuously extending in the tire circumferential direction.

摘要： The invention relates to improving the endurance of the beads of a radial tire for a heavy vehicle of construction plant type, by reducing the cracking that starts at the surface of contact between a first polymer filling material that is radially furthest towards the inside and in contact with the bead wire and a second polymer filling material that is radially on the outside of the first polymer filling material. According to the invention, a transition element, made of a polymer transition material, is in contact, via its radially inner face, with the first polymer filling material and is in contact, via its radially outer face, with the second polymer filling material, and the elastic modulus at 10% elongation of the polymer transition material is somewhere between the respective elastic moduluses at 10% elongation of the first and second polymer filling materials.

摘要： Side lug rows are provided at both side regions of a tread surface and are formed by a plurality of lugs defined by lug grooves opening to edges in the tread width direction, and a central block row aligned on the tire equator and formed by a plurality of blocks is disposed between positions at ¼ of the tread surface width from the tire equator. The tire has a directional tread pattern, with a designated rotation direction, formed by circumferential grooves and width direction grooves that define the blocks of the central block row and are narrow grooves with a narrower groove width than the lug grooves. The distance from the tire equator to the groove wall in each of the circumferential grooves defining the blocks is set to be larger at a leading edge of each block than at a trailing edge of each block.
