Patent ID: 10836214

Abstract:
Provided is a pneumatic motorcycle tire in which, without compromising the stability during running, other performances such as light-weight are improved. Provided is a pneumatic motorcycle tire which comprises a tread portion 1, and side wall portions 2 and bead portions 3 extending from both sides of the tread portion, and whose rotation direction when the tire is mounted on a vehicle is designated. A tire tread is provided with a bent main groove composed of: a first groove 11 extending toward the designated tire rotation direction inclined outside in the tread width direction in a contact region during straight running; a second groove 12 extending from the end portion of the first groove in the reverse rotation direction of the designated tire rotation direction toward the reverse rotation direction of the designated tire rotation direction inclined outside in the tire width direction; and a third groove 13 extending from the end portion of the second groove in the reverse rotation direction of the designated tire rotation direction toward the reverse rotation direction of the designated tire rotation direction inclined outside in the tire width direction, and the bent main groove is formed such that an inclination angle θ3 with respect to the tire circumferential direction of the third groove is larger than an inclination angle θ2 with respect to the tire circumferential direction of the second groove.
