PNEUMATIC TIRE

摘要

A pneumatic tire includes a tread portion provided with a pair of shoulder main grooves adjacent to each tread edge, and shoulder lateral grooves extending from each shoulder main grooves to each tread edge. Each shoulder lateral groove includes an axially inner portion extending from the shoulder main groove with a first angle, an axially middle portion extending from the axially inner portion with a second angle larger than the first angle, and an axially outer portion extending from the axially middle portion with a third angle smaller than the second angle. The shoulder lateral grooves include first and second shoulder lateral grooves alternately arranged in a circumferential direction of the tire. The axially middle portion of the first shoulder lateral groove is disposed axially inwardly of the axially middle portion of the second shoulder lateral groove.

1. A pneumatic tire comprising
a tread portion having a pair of tread edges, the tread portion being provided with a pair of circumferentially and continuously extending shoulder main grooves adjacent to each tread edge and a plurality of shoulder lateral grooves each extending axially outwardly of the tire from each shoulder main groove to each tread edge, each shoulder lateral groove comprising:
an axially inner portion extending from the shoulder main groove having a first angle with respect to an axial direction of the tire;an axially middle portion extending from the axially inner portion having a second angle with respect to the axial direction of the tire larger than the first angle of the axially inner portion; andan axially outer portion extending from the axially middle portion having a third angle with respect to the axial direction of the tire smaller than the second angle of the axially middle portion, and the shoulder lateral grooves including a first shoulder lateral groove and a second shoulder lateral groove, the axially middle portion of the first shoulder lateral groove disposed axially inwardly of the axially middle portion of the second shoulder lateral groove, the first shoulder lateral groove and the second shoulder lateral groove alternately arranged in a circumferential direction of the tire.
