MOTORCYCLE TIRE FOR RUNNING ON ROUGH TERRAIN

摘要

A motorcycle tire for running on rough terrain, the tire includes a tread portion including a central region, a pair of shoulder regions and a middle region. The tread portion is provided with at least one central block with a ground contact face whose centroid is located within the central region, at least one shoulder block with a ground contact face whose centroid is located within the shoulder region on each side of a tire equator, and at least one middle block with a ground contact face whose centroid is located within the middle region on each side of the tire equator. When the respective blocks are projected onto a tire meridian cross section along a circumferential direction of the tire, every pair of axially adjacent two blocks are arranged so as to overlap one another at least partially on the tire meridian cross section.

1. A motorcycle tire for running on rough terrain, the tire comprising:
a tread portion comprising a central region having a development width of one third of a tread development width, a pair of shoulder regions each having a development width of one sixth of the tread development width from each tread edge, and a middle region defined between the central region and one of the shoulder regions on each side of a tire equator; the tread portion being provided with at least one central block having a ground contact face whose centroid is located within the central region, at least one shoulder block having a ground contact face whose centroid is located within the shoulder region on each side of the tire equator, and at least one middle block having a ground contact face whose centroid is located within the middle region on each side of the tire equator; and when the respective blocks are projected onto a tire meridian cross section along a circumferential direction of the tire, every pair of axially adjacent two blocks are arranged so as to overlap one another at least partially on the tire meridian cross section.
