MOTORCYCLE TIRE Russian patent published in 2017 - IPC B60C11/03 B60C11/00 B60C11/117 

FIELD: transport.

SUBSTANCE: tire for motorcycle comprises a tread containing a rubber tread comprising: a central part located in the central zone of a tread comprising the tire equator, a pair of shoulder areas each of which is located on each side and passes from the tread edges, and a pair of middle areas each of which is located between the central and shoulder areas on either side of the tire equator. The central, middle and shoulder areas satisfy the following relations: E*1<E*2<E*3, 0.9tan1/tan21.1≤δδ≤, and≤δδ≤ 0.9tan2/tan31.1, where E*1, E*2 and E*3 are the complex modules of the central, middle areas and a shoulder area elasticity, respectively, and tan1δ, tan2δ and tan3δ are loss angles tangents of central, middle and a shoulder areas, respectively.

EFFECT: invention provides higher driving stability and driving comfort.
