    摘要： A pneumatic tire having a belt reinforcement layer capable of increasing riding comfortableness and steering stability. The belt reinforcement layer (35) having a high bending rigidity in the circumferential direction and a fitted belt ply (25) having a higher bending rigidity in the circumferential direction next to the belt reinforcement layer are collected near the neutral axis of bending present near the boundaries thereof by increasing the circumferential bending rigidity of the fitted belt ply (25) disposed fittedly to the belt reinforcement layer (35) more than that of a separating belt ply (24). Thus, the longitudinal spring constant of the pneumatic tire (11) can be reduced and the ground-contact length thereof can be increased by lowering the synthetic circumferential bending rigidity of the belt layer (23) and the belt reinforcement layer (35).

    摘要： An object is to improve noise performance of a tire while enhancing movement performance thereof. At least one of the land portions (20) includes an outer wall surface (30) positioned on a vehicle outer side, an inner wall surface (31) positioned on a vehicle inner side, a tread surface (32) on an outer side in a tire radial direction, an outer edge (33) of the tread surface (32) in contact with the outer wall surface (30), and an inner edge (34) of the tread surface (32) in contact with the inner wall surface (31). The tread surface (32) is formed in a convex shape which is smoothly curved between the outer edge (33) and the inner edge (34) and which has a top portion (43) most protruded outward in the tire radial direction, in a cross section of the land portion (20) in a tire width direction. A relationship of Do

    摘要： A pneumatic tire whose durability is increased, even if a folded belt layer using organic fiber cords is used, by dispersing or reducing compression force acting on the organic fiber cords in width end sections of the folded belt layer. A pneumatic tire (1) has a toroidally extending carcass (3) and a belt (7) composed of belt layers (5, 6) located on the outer periphery side of a crown section (4) of the carcass (3). A crossing belt in which cords (8, 9) intersect each other across an equator surface (E) is formed between adjacent belt layers (5, 6). The belt layer (6) with the greatest width is a folded belt layer having a body section (10) and folded sections (12), and a cord (9) constituting the folded belt layer (6) is an organic fiber cord. Narrow width belt reinforcement layers (14) constructed by coating cords (13) with rubber are arranged at positions directly under width end sections (11) that are continuous to the folded sections (12) of the body section (10) of at least the folded belt layer (6).
