摘要： In a pneumatic tire 1, a side surface (101), on a buttress portion (14) side, of a land portion block (100) is inclined to the inside of the land portion block (100). The length (Lb1), in a tread width direction, of an and portion (100B) of the land portion block (100) is smaller than the length (La1), in the tread width direction, of an end portion (100A). The end portion (100B) is located at a rear side in a rotational direction (R) in which the pneumatic tire (1) installed on a vehicle rotates when the vehicle moves forward, and the end portion (100A) is located at a front side in the rotational direction (R).

摘要： An of object of the present invention is to provide a pneumatic tire which exhibits improved durability of a bead portion due to further suppressing compression strain at a carcass ply fold-up portion and, in particular, suppressing fatigue fracture at the carcass ply fold-up portion. Cord distance between the carcass main body and the carcass ply fold-up portion gradually decreases from the bead core toward the outer side in the tire radial direction to reach the minimum value a, then gradually increases to the maximum value b; provided that height Hf of a flange of an application rim, measured from a base line of the application rim in a state where the tire is assembled with the rim and inflated at a prescribed internal pressure, is 1, heights HA and HB measured from the base line to the positions on the carcass main body corresponding to the minimum and the maximum values, respectively, and the maximum height HT of the tire satisfy relationship formulae below, HT≧8.00 1.26≦HA≦2.14 2.43≦HB≦3.75; and a value of ratio (b/a) of the maximum value b with respect to the minimum value a of distance between cords of the carcass main body and the carcass ply fold-up portion exceeds 1.00.

摘要： In a tire according to the present invention, a groove portion extending in a tire circumferential direction is formed in a tread portion 20. A groove portion 30 extending in a tire circumferential direction is formed in the tread portion 20. In a groove bottom 32 of the groove portion 30, a plurality of protrusion portions 100 are provided. The protrusion portions 100 extend from one sidewall 31 forming the groove portion toward the other sidewall 33 facing the one sidewall. When the length of the protrusion portions 100 along the groove center line WL is L and a predetermined interval is P, in a tread surface view of the tire, the relation of 0.75 L≦P≦10 L is satisfied.
