Japanese Patent JP7464833
Kind Code:
B2
Abstract:
To provide a pneumatic tire capable of improving a communication property of a transponder while maintaining good tire balance.SOLUTION: A pneumatic tire comprises: a tread portion extending in a tire circumferential direction to form an annular shape; a pair of sidewall portions arranged on both sides of the tread portion; and a pair of bead portions arranged on an inner side of a tire radial direction of these sidewall portions. A transponder 20 is embedded in the sidewall portion so as to extend along the tire circumferential direction. The transponder 20 is covered with a coating layer 23. A relative permittivity of the coating layer 23 is lower than a relative permittivity of a peripheral rubber member adjacent to the covering layer 23. A tire circumferential length Lc of the coating layer 23 and a tire circumferential length Lr of the transponder 20 satisfy a relation of 1.1≤Lc/Lr≤2.0.SELECTED DRAWING: Figure 6
