Claims

[Scope of utility model registration request]

In a tire that has a tread in which a ground contact portion is set by a groove, and rotates with the contact surface of the ground contact portion in contact with the road surface, the ground contact surface of the ground contact portion is in contact with the road surface and rotates. A wear indicator whose cross-sectional area is reduced is buried in the ground contact part so that one end thereof is exposed on the ground contact surface. A tire wear display structure that is characterized by a decrease in tire wear.
