Abstract
A two-wheeled vehicle tire includes a tread portion having a designated rotational direction and being provided with at least three kinds of blocks including first blocks each having a trailing edge extending substantially in parallel with a tire axial direction, second blocks each having a trailing edge inclined a first direction with respect to the tire axial direction and third blocks each having a trailing edge inclined in a second direction opposite to the first direction with respect to the tire axial direction. At least two different kinds of blocks selected from a group of the first blocks, the second blocks and the third blocks are provided on each of a crown region, middle regions and shoulder regions of a tread portion.
Claims16
A two-wheeled vehicle tire comprising:
- a tread portion having a designated rotational direction and being provided with a plurality of blocks;
- the tread portion comprising a crown region with a tire equator wherein the crown region is a region that comes into contact with the ground when straight traveling and when cornering with a small camber angle, a pair of middle regions each located axially outwardly of the crown region wherein the middle regions are regions that come into contact with the ground when cornering and a pair of shoulder regions each located axially outwardly of the shoulder regions wherein the shoulder regions are regions that come into contact with the ground when cornering with a large camber angle;
- each of the blocks having a top surface with a straightly extending trailing edge located backwardly in the rotational direction;
- the blocks comprising at least three kinds of blocks including
- first blocks each having the trailing edge extending substantially in parallel with a tire axial direction,
- second blocks each having the trailing edge inclined in a first direction with respect to the tire axial direction such that an axially outer side of the trailing edge is located forwardly in the rotational direction with respect to an axially inner side thereof, and
- third blocks each having the trailing edge inclined in a second direction opposite to the first direction with respect to the tire axial direction such that an axially inner side of the trailing edge is located forwardly in the rotational direction with respect to an axially outer side thereof;
- and
- at least two different kinds of blocks selected from a group of the first blocks, the second blocks and the third blocks being provided on each of the crown region, middle regions and shoulder regions,
- wherein a total number of the first blocks is the least in the three kinds of blocks.

- each of the blocks having a top surface with a straightly extending trailing edge located backwardly in the rotational direction;
- the blocks comprising at least three kinds of blocks including
- first blocks each having the trailing edge extending substantially in parallel with a tire axial direction,
- second blocks each having the trailing edge inclined in a first direction with respect to the tire axial direction such that an axially outer side of the trailing edge is located forwardly in the rotational direction with respect to an axially inner side thereof and
- third blocks each having the trailing edge inclined in a second direction opposite to the first direction with respect to the tire axial direction such that an axially inner side of the trailing edge is located forwardly in the rotational direction with respect to an axially outer side thereof;
- and
- at least two different kinds of blocks selected from a group of the first blocks, the second blocks and the third blocks being provided on each of the crown region, middle regions and shoulder regions, wherein
- a total number of the first blocks is in a range of from 10% to 40% of a total number of the blocks,
- a total number of the second blocks is in a range of from 30% to 50% of the total number of the blocks, and
- a total number of the third blocks is in a range of from 30% to 50% of the total number of the blocks.
