AI Technical Summary
Technical Problem
Existing tires face a challenge in achieving both snow performance and low rolling resistance, as conventional designs often compromise on one or the other.
Method used
The tire design incorporates a plurality of main grooves with specific narrow grooves arranged in a V-shape, ensuring edge components in both circumferential and width directions, while maintaining land portion rigidity by spacing apart the grooves to reduce rolling resistance.
Benefits of technology
This design enhances snow acceleration and anti-skid performance while reducing rolling resistance by ensuring land portion rigidity and optimizing groove arrangements.

Abstract
To provide a tire capable of having both tire snow performance and low rolling resistance performance.SOLUTION: In a tire 1, a center land part 33 comprises: first center thin grooves 331 having one end on an edge of the center land part 33, connected to a center main groove 22, and having the other end in the center land part 33; and second center thin grooves 332 extending in a tire circumferential direction and having both ends in the center land part 33. The first center thin grooves 331 are inclined in one direction in the tire circumferential direction toward the other end from the one end. The first center thin grooves 331 and the second center thin grooves 332 are arrayed in a V-shape with an apex facing the one direction in the tire circumferential direction, and disposed to be separated from each other.SELECTED DRAWING: Figure 3
