摘要
A tread portion of a pneumatic tire includes a columnar wear measurement magnet that has magnetic flux density or magnetic field strength formed thereby decreased due to wear thereof along with wear of tread rubber of the tread portion and a columnar reference magnet provided at a position where the columnar reference magnet is not worn with the wear of the tread rubber. The wear measurement magnet and the reference magnet extend from a tread surface side toward a tire cavity region of the pneumatic tire, and an end of the reference magnet on the tread surface side is located farther from a tread surface where the tread portion contacts the ground than an end of the wear measurement magnet on the tread surface side.
