Abstract
A pneumatic tire includes: a tread portion extending in a tire circumferential direction and having an annular shape; a pair of sidewall portions disposed on both sides of the tread portion; and a pair of bead portions disposed on an inner side in a tire radial direction of the sidewall portions. The tire is embedded with a transponder covered with a covering layer. A modulus M50 (0° C.) at 50% deformation at 0° C. of the covering layer is in a range of from 0.5 MPa to 2.0 MPa, and a modulus M50 (−20° C.) at 50% deformation at −20° C. of the covering layer and the modulus M50 (0° C.) at 50% deformation at 0° C. of the covering layer satisfy a relationship 1.0<M50 (−20° C.)/M50 (0° C.)≤2.5.
