二輪車用空気入りタイヤ
Document Type and Number:
Japanese Patent JP4289685
Kind Code:
B2
Abstract:
A pneumatic tire for two-wheeled vehicles that has excellent steering stability during high-speed traveling while having excellent steering stability performance during turning, in which the vehicle body is significantly tilted, with improved grip performance during turning. The pneumatic tire for two-wheeled vehicles includes a spiral belt layer (22) and a plurality of tread rubbers constituting a tread (28). When a region occupying 15 to 35% in the center of a stretched tread width, which is obtained by stretching the tread (28) with respect to a tire equatorial plane as the center, is defined as a tread central section; the remaining regions at both ends are defined as tread side sections; regions in the respective tread side sections each occupying 4 to 13% from the corresponding tread end toward the center of the stretched tread width are defined as side-section shoulder-end regions; and the remaining regions of the respective tread side sections are defined as side-section near-center regions, a modulus M1 of the tread rubbers (30A) for the side-section shoulder-end regions at 100% elongation is smaller than a modulus M2 of the tread rubbers (30B) for the side-section near-center regions at 100% elongation, at least at a tread surface.
