AI Technical Summary
Technical Problem
Motorcycle tires for rough terrain travel face a challenge in balancing traction performance with slide control during straight and turning maneuvers, as increasing traction often leads to reduced slide control during cornering.
Method used
A motorcycle tire design with a specified tread configuration featuring crown and middle blocks, where crown blocks have varying tread shapes and orientations, and middle blocks are positioned to enhance traction while maintaining slide control, including specific angles and separations to optimize shear force distribution.
Benefits of technology
The tire design enhances traction performance while effectively suppressing a significant decrease in slide control performance during cornering.

Abstract
To provide a motorcycle tire that enhances traction performance while suppressing a significant decrease in slide control performance during cornering. [Solution] This is a motorcycle tire 1. The first crown block 6 has a V-shaped leading edge 11. The total number of first crown blocks 6 is 30% or more of the total number of crown blocks 4. The leading edge 11 is inclined at an angle α1 of 10 to 45 degrees. The middle block 5 is located closer to the second crown block 7 than the first crown block 6. The middle block 5 and the second crown block 7 are separated in the circumferential direction of the tire, or they overlap by a circumferential distance DO of 0.5 times or less the longitudinal length LC.
