<p>At least one alerting layer (221,222) of a different color than a tire surface (20) is divided into a rubber layer of the tire, in accordance with a safe abrasion condition of the tire, wherein a default distance of a lowest alerting layer to the tire surface is less than a depth of tire tread. Before the tire tread (21) is worn out, the alerting layer (221,222) of a default color will be emerged at a part of the tire that is abraded, due to a different extent of abrasion, which facilitates a consumer to check a degree of safety of the tire by oneself by a direct visualization method, and can prevent unworthy practicers to trick the consumer to replace the tire, while it has not achieved a standard of abrasion.</p> |
