motorcycle tires

Abstract

The invention provides a motorcycle tire capable of improving a side inclining characteristic while not reducing road holding performance and wear-resisting performance. The first area (11) and a second area (12) of a tread portion (2) are provided with inner-side inclined trenches (30) comprising first inner-side inclined trenches (13) and second inner-side inclined trenches (23); and outer-side inclined trenches (40) comprising first outer-side inclined trenches (14) and second outer-side inclined trenches (24). The circumferential length B1 of the tire of the outer-side inclined trenches (40) are less than the circumferential length A1 of the tire of the inner-side inclined trenches (30). The axial length B2 of the tire of the outer-side inclined trenches (40) along the thread-ground surface is more than axial length A2 of the tire of the axial length A2 of the tire of the inner-side inclined trenches (30) along the thread-ground surface. The outer-side inclined trenches (14) and the outer-side inclined trenches (24) are extended out of a non-projection area (P2) and a projection area (P1), respectively. The circumferential distance D1 of the tire and the circumferential distance D2 of the tire are from 30 to 70% of the length of A1-B1.

Description

technical field [0001] The present invention relates to a motorcycle with improved roll characteristics. Background technique [0002] In order to improve the cornering performance of motorcycle tires, it is required to improve the transition characteristics when the camber angle is imparted (hereinafter, sometimes referred to as "roll characteristics"). [0003] Specifically, motorcycle tires are required to easily roll the vehicle body at the initial roll stage when the camber angle is small. Therefore, it is desirable that the rigidity of the crown region where the roll initially touches the ground is smaller than the rigidity of the shoulder region and the middle region. [0004] In addition, motorcycle tires are required to be easy to suppress the camber angle in the mid-to-late roll phase when the camber angle is large. It is therefore desirable that the shoulder areas in contact with the tire at full tilt be stiffer than the middle and crown areas. Furthermore, it ...

Problems solved by technology

[0008] However, even the tire for motorcycles described in Patent Document 1 cannot sufficiently balance roll characteristics, grip performance, and wear resistance, and further improvement is required.
