<P>PROBLEM TO BE SOLVED: To provide a tire capable of sufficiently restraining nonuniform abrasion of early abrading a rail abutting area more than a rail unabutting area, without sacrificing on-ice/snow performance on a road so much, in the tire used for both travel on the road and travel on a rail of a track. <P>SOLUTION: This tire 100 is characterized in that at least two circumferential directional grooves 11, 12, 15 and 16 are arranged in a tread part 10, a rib-like land part 13 is partitioned and formed, a plurality of width directional grooves 21 and 22 are arranged at an interval in the tire circumferential direction outside in the tire width direction of the two outermost peripheral directional grooves 11 and 12 positioned outermost in the tire width direction among the circumferential directional grooves, block land part groups 20 constituted of a plurality of block land parts 24 and 25 are partitioned and formed, the rib-like land part 13 is at least positioned over the whole rail abutting area T of the tread part 10, and the block land part groups 20 are positioned in the rail unabutting areas N of the tread part 10. <P>COPYRIGHT: (C)2012,JPO&INPIT |
