Abstract
A tire 1 in which the communication device includes a RF tag 10e and a tag coating rubber portion 10f coating the RF tag, the communication device is disposed between the side rubber and the bead filler, a 100% modulus M100 of the side rubber is lower than a 100% modulus M100 of the tag coating rubber portion, a 100% modulus M100 of the tag coating rubber portion is lower than a 100% modulus M100 of a contacting bead filler portion of the bead filler in contact with the communication device, a loss tangent tan δ of the side rubber is greater than a loss tangent tan δ of the contacting bead filler portion, and a thermal conductivity of the carcass cord is higher than a thermal conductivity of each of the contacting bead filler portion and the tag coating rubber portion.
