Finned Off-Road Motorcycle Tire Blocks for Traction and Cornering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current motorcycle tires for rough terrain lack optimal combined traction and cornering performance, as existing designs do not effectively enhance edge components and block configurations to improve friction and stability on uneven surfaces.
Innovation Solution
A tire design featuring finned blocks with projections between fin portions on the base surface, where the finned blocks are formed with a block main body and two fin portions extending in the tire circumferential direction, and a projection is placed between these fin portions to enhance traction and cornering by suppressing deformation and providing additional edge components.

Engineering Contradiction Analysis
1Stability of the object's composition
If block deformation is suppressed to improve stability, then handling stability is improved, but friction and traction are reduced
Solution Approach 1:
The finned block design allows controlled deformation characteristics: the fin portions can deform to adapt to terrain irregularities and increase friction, while the overall block structure maintains stability through the geometric configuration of multiple fin portions and projections. This dynamic response resolves the contradiction between stability and friction

AI summary
An object is to improve combined performance of traction performance and cornering performance in a tire for a motorcycle for running on rough terrain. The tire is a tire for a motorcycle for running on rough terrain, including a tread portion 2. The tread portion 2 includes a base surface 8 and a plurality of blocks 10 raised outward in a tire radial direction from the base surface 8. At least one of the plurality of blocks 10 includes a finned block 15. The finned block 15 includes a block main body 16 and at least two fin portions 17 having a smaller width in a tire axial direction than the block main body 16 and extending to one side in a tire circumferential direction. A projection 18 is provided between the two fin portions 17 on the base surface 8.
