Abstract
In a pneumatic tire with a carcass layer mounted between a pair of bead portions, a transponder is embedded in an outer side of the carcass layer in the tire width direction, a rubber member having the largest storage modulus at 20° C. of rubber members located on an outer side of the transponder in the tire width direction has a modulus M50out(0° C.) during 50% deformation at 0° C. and a modulus M50out(−20° C.) during 50% deformation at −20° C. that satisfy a relationship 0.50≤M50out(0° C.)/M50out(−20° C.)<1.00, and a rubber member having the largest storage modulus at 20° C. of rubber members located on an inner side of the transponder in the tire width direction has a modulus M50in(0° C.) during 50% deformation at 0° C. and a modulus M50in(−20° C.) during 50% deformation at −20° C. that satisfy a relationship 0.25≤M50in(0° C.)/M50in(−20° C.)<1.00.
