The tire includes a power receiving coil that receives an AC magnetic field from outside the tire and generates power. The power receiving coil is provided on a sidewall inner surface facing a tire cavity region of the tire in a sidewall portion between a tread portion and a bead portion, and generates AC power by receiving an AC magnetic field transmitted through the sidewall portion. The power receiving coil is a circular coil extending along the sidewall inner surface so as to surround a single circle in the tire circumferential direction. The ratio Ts/Tmin is 1.0-5.5, where Ts is the thickness of the sidewall portion at a position where the power receiving coil is provided on the sidewall inner surface, and Tmin is the minimum thickness of the sidewall portion in the tire radial direction.
轮胎具备接受来自轮胎外部的交流磁场而产生电力的受电线圈。受电线圈设置在位于胎面部与胎圈部之间的胎侧部的面向所述轮胎的轮胎空腔区域的胎侧内表面,通过接受透过所述胎侧部的交流磁场来产生交流电力。所述受电线圈是沿着所述胎侧内表面以在轮胎周向上环绕一周的方式延伸的圆形线圈。在将所述胎侧内表面上设置有所述受电线圈的位置处的所述胎侧部的厚度设为Ts、将所述胎侧部的跨越轮胎径向的厚度中的最小厚度设为Tmin时,比Ts/Tmin为1.0~5.5。
