Abstract

The invention provides a tire which not only maintains wet road performance but also has excellent partial wear resistance. The tire has a tread portion (2) specifying a mounting direction to a vehicle. The first bezel (16a) and the second bezel (16b) of the outer shoulder lateral groove (16) provided on the outer shoulder land portion (10) respectively meet the outer tread end (To) at a first intersection point (21 ) and the second intersection point (22) intersect. The third bezel (17a) and the fourth bezel (17b) of the inner shoulder lateral groove (17) provided on the inner shoulder land portion are at the third intersection (23) and the third intersection (23) and the fourth bezel respectively with the inner tread end (Ti). The four intersections (24) intersect. The first intersection point (21) and the second intersection point (22) are respectively provided at different positions in the tire circumferential direction from the third intersection point (23) and the fourth intersection point (24).

Description

technical field

[0001] The present invention relates to a tire having excellent uneven wear resistance. Background technique

[0002] For example, Patent Document 1 below proposes a tire having a tread portion in which a direction of mounting on a vehicle is specified. The tire has an outer shoulder land portion positioned outside the vehicle when mounted on the vehicle, and an inner shoulder land portion positioned inside the vehicle when mounted on the vehicle. A plurality of outer shoulder lateral grooves extending inward in the tire axial direction from the tread end are provided on the outer shoulder land portion. A plurality of inner shoulder lateral grooves extending inward in the tire axial direction from the tread end are provided on the inner shoulder land portion. The above-mentioned shoulder lateral grooves allow water in the ground contact surface to drain toward the tread end side, thereby improving wet road performance.

[0003] In the above tire, the bead ...
