Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a four-season tire pattern. Background Art

[0002] According to research, many car owners still use summer tires in winter. Due to their inherent formula and tread design, summer tires have reduced grip in low-temperature conditions, especially on icy and snowy roads, posing a safety hazard to consumers. Replacing winter tires not only increases costs but also causes significant inconvenience for car owners. Therefore, the research and development of all-season tires has emerged.
