Abstract
A tire comprises: a belt composed of one or more belt layers; a main groove on a tread surface; and a communication device embedded at a position that is inward in a tire radial direction from a groove bottom of the main groove, outward in the tire radial direction from an inner surface of an innermost belt layer in the belt, and outward in a tire width direction from a minimum width belt layer in the belt, wherein a tire radial outer side of the communication device is not covered with the belt.
Claims3
A retreaded tire comprising:
- a base tire that includes a belt composed of one or more belt layers and is obtained as a result of removing a tire radial outer part from a position that is outward in a tire radial direction from an outer surface of an outermost belt layer in the belt;
- an annular rubber member embedded in the base tire and extending in a tire circumferential direction;
- a communication device embedded in part of the annular rubber member at a position that is outward in the tire radial direction from an inner surface of an innermost belt layer in the belt and outward in a tire width direction from a minimum width belt layer in the belt;
- and
- a tread member adhered to a tire radial outer side of the base tire,
- wherein a tire radial outer side of the communication device is not covered with the belt,
- the annular rubber member is placed between the base tire and the tread member, and
- the annular rubber member is formed from a rubber material having lower carbon content and higher conductivity than a rubber material of the base tire located around the annular rubber member.
