摘要： PROBLEM TO BE SOLVED: To prevent a run flat durability from being lowered without reducing degree of freedom in design of a tread pattern.
SOLUTION: There are provided a radial carcass 6 and a reinforcing rubber layer 10 arranged between the carcass 6 and an inner liner 9 at its inner circumferential side at a portion corresponding to the side wall 2. This is positioned outside a tread ground contact width under an attitude where a load of 1.1 times of a maximum load capability is applied while filling a maximum pneumatic pressure in a rim assembled tire. In turn, under an attitude in which the tire inner pressure is reduced down to an atmospheric pressure and a mass corresponding to the maximum load capability is applied, a circumferential groove 11 positioned inside the tread ground contact width and continuous circumferentially is arranged at an outer surface of the shoulder region and a depth of each of the circumferential grooves is set to be more than 1/4 of a total tire thickness before forming the circumferential groove. Further, a circumferentially extending angle of the circumferential groove 11 is set at 0 to 30° and then a fibrous reinforcing layer 12 independent from another reinforcing member is arranged in a band-like manner in an area overlapping on the circumferential groove at the inner circumferential side of the circumferential groove 11.

In this case, the belt cord plies 3 are constituted of the cord embedded in a shoulder part of the tire and more than 0.30 in its twist coefficient and another cord embedded in a grounding surface central zone of the rest and less than 0.60 in its twist coefficient. And, a ratio of the twist coefficient of each of these cords should be set to a range of 1.2-1.8. With this constitution, a standing wave in the shoulder part is prevented from occurring and simultaneously one-sided wear is restrainable.
