tire

Abstract

PROBLEM TO BE SOLVED: To provide a tire having excellent wet performance.SOLUTION: A tire has a tread part 2 in which a direction of mounting to a vehicle is specified. The tread part 2 includes: an outer shoulder land part 10 having an outer tread end; an outer middle land part 11 adjacent to the outer shoulder land part 10; and an outer shoulder main groove 3 extending in a tire circumferential direction therebetween. The outer shoulder land part 10 is provided with a plurality of outer shoulder lateral grooves 15. The outer middle land part 11 is provided with a plurality of first outer middle lug grooves 18. Each of the first outer middle lug grooves 18 is arranged at a position where the groove smoothly continues to any of the outer shoulder lateral grooves 15 through the outer shoulder main groove 3. Each of the outer middle lug grooves 18 is a bent groove which includes an outer part 21 at an outer shoulder main groove 3 side and an inner part 22 having an angle relative to the tire circumferential direction smaller than that of the outer part 21.SELECTED DRAWING: Figure 1

Description

technical field [0001] The present invention relates to tires having excellent wet performance. Background technique [0002] For example, Patent Document 1 below proposes a tire in which outer shoulder lateral grooves and outer middle sipes are provided in a tread portion in communication with outer shoulder main grooves. In order to improve the wet performance, the outer middle sipes of this tire are arranged at positions that smoothly continue to the outer shoulder lateral grooves with the outer shoulder main grooves interposed therebetween. [0003] However, the entire outer middle sipe of Patent Document 1 is inclined at a constant angle. Such an outer middle sipe groove tends to make it difficult for water in the groove to move toward the outer shoulder main groove side when running on a wet road, and there is still room for further improvement in wet road performance.

AI Technical Summary

Problems solved by technology

[0003] However, the outer middle sipes of Patent Document 1 are inclined at a constant angle as a whole.

Such an outer middle tread groove tends to make it difficult for the water in the groove to move to the outer shoulder main groove side when driving on a wet road, and there is still room for further improvement in the improvement of the wet road performance.
