Abstract
Official abstract text for this publication.
A winter tire includes a tread portion provided with first inclined main grooves extending from a first tread edge near a tire equator, second inclined main grooves extending from a second tread edge near the tire equator, a first inner longitudinal groove connecting a pair of first inclined main grooves at the vicinity of the tire equator and a second inner longitudinal groove connecting a pair of second inclined main grooves at the vicinity of the tire equator. Each of the first inclined main grooves includes an axially first inner end portion extending along an axial direction of the tire to the second inner longitudinal groove, and each of the second inclined main grooves includes an axially second inner end portion extending along the axial direction of the tire to the first inner longitudinal groove.
First claim
Opening claim text (preview).
What is claimed is: 1 . A winter tire comprising: a tread portion being provided with a plurality of first inclined main grooves extending from a first tread edge to or near a tire equator, a plurality of second inclined main grooves extending from a second tread edge to or near the tire equator, a first inner longitudinal groove connecting a pair of adjacent first inclined main grooves at the vicinity of the tire equator and a second inner longitudinal groove connecting a pair of adjacent second inclined main grooves at the vicinity of the tire equator; the first inclined main grooves and the second inclined main grooves being arranged alternately in a circumferential direction of the tire; each of the first inclined main grooves comprising an axially first inner end portion extending along an axial direction of the tire to the second inner longitudinal grooves; and each of the second inclined main grooves comprising an axially second inner end portion extending along the axial direction of the tire to the first inner longitudinal grooves. 2 . The winter tire according to claim 1 , wherein the first inner longitudinal groove is located between the first tread edge and the tire equator, the first inner longitudinal groove comprises a bending portion protruding toward the tire equator, and one of the second inner end portions is connected to the bending portion of the first inner longitudinal groove. 3 . The winter tire according to claim 2 , wherein the second inner longitudinal groove is located between the second tread edge and the tire equator, the second inner longitudinal groove comprises a bending portion protruding toward the tire equator, and one of the first inner end portions is connected to the bending portion of the second inner longitudinal groove. 4 . The winter tire according to claim 1 , wherein the first inner end portions are arranged on a different location with respect to the second inner end portions in the axial direction of the tire. 5 . The winter tire according to claim 1 , wherein the tread portion is further provided with a first inner lateral groove that extends axially outward from the first inner longitudinal groove with an opposite inclination direction to the first inclined main grooves. 6 . The winter tire according to claim 1 , wherein the tread portion is further provided with a second inner lateral groove that extends axially outwardly from the second inner longitudinal groove with an opposite inclination direction to the second inclined main grooves.
