PROBLEM TO BE SOLVED: To reduce the abrasion of a tire performing rotation/driving while abutting on a rail. SOLUTION: In the tire 50 used for both of traveling on a road and traveling on a rail of a track, regarding two circumferential grooves formed at both outer sides of an abutment area T of the rail among a plurality of circumferential grooves 52, 53 formed along a tire circumferential direction on a tread surface 51, width is formed more widely than the other circumferential groove 52. Thereby, it is deflected such that a block escapes to the circumferential groove side of wide width to cancel the pressure-contact state with the rail. COPYRIGHT: (C)2007,JPO&INPIT |
