Abstract

PURPOSE: To prevent separation of a jacket rubber from a cord layer by absorbing distortion liable at the projection's side wall through provision of a tread part having a peculiar ring-shaped projection and a peculiar groove bottom's profile.
CONSTITUTION: The mating surface 9 of a ring-shaped projection 8 against the flange 24 is provided with an carvature having in profile a radius larger than that of the flange's upper edge and with a radial distance from the wheel axis of such a magnitude that its difference from that of the rim flange produces a gap a measuring 1/10W5/10 of the flange height when the tire 1 and the rim are assembled. The tread part 4 is composed of a central zone 10 approx. parallel to the rotation axix and with a width of 10W70% of the tire's maximum width at the groove bottom position and side zones 11 inclined from this central zone 10 toward the rotation axis, having an inclination angle α of at least 10°.
