AI Technical Summary
Technical Problem
Existing all-terrain tires struggle to improve pass-by noise performance while maintaining snow performance, as previous designs focus on wet performance and crack resistance without addressing noise reduction.
Method used
The tire design features circumferential grooves and lug grooves with convex portions on their walls, where the distance from the tread surface to the convex portions gradually decreases from one end to the other, enhancing snow removal and reducing noise.
Benefits of technology
The design effectively improves pass-by noise performance while maintaining snow performance by effectively pushing snow out of the grooves and preventing sound leakage.

Abstract
To improve passing noise performance while maintaining snow performance of a tire.SOLUTION: A tread portion of a tire includes a circumferential groove extending in a tire circumferential direction and a lug groove extending in a tire width direction, one end of the lug groove is connected to the circumferential groove, and the other end of the lug groove is connected to an end portion of the tread portion. A protrusion provided on a groove wall of the lug groove and extending in a groove length direction of the lug groove, wherein a distance from a tread surface of the tread portion to the protrusion gradually decreases from one end of the lug groove toward the other end of the lug groove.SELECTED DRAWING: Figure 1
