<p>PROBLEM TO BE SOLVED: To improve rim assembling performance and oscillation comfortableness by providing an one-layer cushion rubber layer having a specific loss tangent between an end portion of a belt in both shoulder areas of a tread part of the belt reinforcing the tread part on an outer periphery of a carcass and a rubber layer in the shoulder area. SOLUTION: A vehicular pneumatic tire 1 is provided with a belt 7 reinforcing a tread part 4 on an outer periphery of a carcass 6, and provided with a reinforcing rubber layer 9 on an inner surface side of a turn up ply 6-1 of the carcass 6. The belt 7 has an end portion of a steel cord layer forming steel cord crossing layers 7-1, 7-2 in both shoulder areas, and a cushion rubber layer 11 is provided between each of structure members of the tire 1 adjacent to each other, between an end portion of the belt 7 and the reinforcing rubber layer 9 in the shoulder area. Rubber having a loss tangent value not more than that of a cord covering rubber of the ply 6-1, 6-2 of the carcass 6 is used for the cushion rubber layer 11.</p> |
