PURPOSE:To generate a large cornering force and prevent road surface gripping force from decreasing with the lapse of time. CONSTITUTION:A tread part 1 of a tire is provided with plural circumferential grooves 2, 3a, 3b, 4a and 4b. When a chassis equipped with the tire is viewed from the front, at least the groove center line 7, within a cross section in the tread width direction, of the circumferential groove 4a located outer of chassis than the other grooves is inclined in a direction where an outer part in the radial direction of the tire is located in the central side of the tread relative to the inner part in the radial direction. The tread wall 10 of the tread edge side is inclined so that the groove width increases gradually at an outer edge part in the radial direction of the tire.
