PROBLEM TO BE SOLVED: To provide a tire having improved heating durability without increasing members. SOLUTION: On a tread part 18 of the tire on the tire-radial-direction outside of a belt layer 14, a shoulder block train 32 is formed by peripheral grooves and transverse grooves. Each of blocks constituting the shoulder block train 32 has a shallow groove 40 formed along a tire peripheral direction. The shallow groove 40 is located on the tire-radial-direction outward side of a belt end 14T of a third belt 14C as a tire-radial-direction outermost belt. COPYRIGHT: (C)2010,JPO&INPIT |
