PNEUMATIC TIRE
In a pneumatic tire in which a carcass layer is turned up from a tire inner side to a tire outer side around a bead core, an end of a turned up portion of the carcass layer is disposed between a body portion of the carcass layer and a belt layer, a transponder that extends along time circumferential direction is embedded between the turned up portion of the carcass layer and a rubber layer disposed in a sidewall portion on an outer side of the carcass layer, and the transponder is disposed between a position (P1) located on an outer side of and 15 mm away from an upper end of the bead core in a tire radial direction and a position (P2) located on an inner side of and 5 mm away from an end of the belt layer in the tire radial direetion
