    摘要: In a pneumatic tire composed of a carcass layer crossing between a pair of left and right bead cores, the bead cores comprise a fastening bead core for fastening an end of the carcass layer to be turned up around the fastening bead core, and a non-fastening bead core free from the end of the carcass layer. An inner circumferential radius R2 of the non-fastening bead core is set smaller than an inner circumferential radius R1 of the end of the carcass layer to be turned up around the fastening bead core.

    摘要: Disclosed are a tire/wheel assembly and a run-flat support member which are designed to be lightened without losing durability during run-flat traveling. The tire/wheel assembly is constituted as follows: a pneumatic tire is fit to a wheel rim; and the run-flat support member constituted of a circular shell and elastic rings is inserted into a cavity of the pneumatic tire. The circular shell has a support surface thereof extended toward the periphery of the pneumatic tire and leg portions along each side of the support surface. The elastic rings support the leg portions of the circular shell on the rim. In the tire/wheel assembly, contact portions and noncontact portions for the circular shell are alternately formed on the elastic rings in a shell circumferential direction.

    摘要: A large number of sub-grooves inclining in the same direction as a tire rotating direction of a tire circumferential direction towards the outside of a car and extending in a tire width-wise direction are disposed on a tread surface of a tire the tire rotating direction of which is designated in one direction, and at least one main groove extending straight in the tire circumferential direction is disposed in an inside region of the tread surface inner than a tire center line. Further, semi-main grooves crossing the sub-grooves and inclining in an opposite direction to that of the sub-grooves are disposed at a predetermined pitch in the tire circumferential direction in an outside region of the tread surface outer than the tire center line. In this way, a pneumatic radial tire of the present invention has a block type tread pattern having asymmetric directionality.
