To suppress generation of uneven wear in a tire, and to assure on-ice snow performance of the tire, thereby achieving both of uneven wear-resistant performance and on-ice snow performance.SOLUTION: Separation blocks 51 are positioned on both sides of a pair of compartment sipes 24 in a tire circumferential direction S, and are so formed as to be separated from each other in the tire circumferential direction S. A step block 52 is partitioned between the pair of compartment sipes 24, and forms a step on the separation block 51 by a tread 54 which is positioned on a tire radial direction inner side with respect to a tread 53 of the separation block 51. An adjacent block 61 is adjacent to a tire width direction H with a circumferential groove 12 interposed therebetween with respect to the separation block 51 and the step block 52, and contacts the separation block 51 without contacting the step block 52 at the time of grounding.SELECTED DRAWING: Figure 2 【課題】タイヤに偏摩耗が発生するのを抑制するとともに、タイヤの氷雪上性能を確保して、耐偏摩耗性能と氷雪上性能とを両立させる。【解決手段】離隔ブロック５１は、一対の区画サイプ２４のタイヤ周方向Ｓの両側に位置し、タイヤ周方向Ｓに離隔して形成される。段差ブロック５２は、一対の区画サイプ２４の間に区画され、離隔ブロック５１の踏面５３よりもタイヤ半径方向の内側に位置する踏面５４により、離隔ブロック５１に対して段差を形成する。隣接ブロック６１は、離隔ブロック５１と段差ブロック５２に対して周方向溝１２を挟んでタイヤ幅方向Ｈに隣接し、接地時に、段差ブロック５２と接触せずに離隔ブロック５１と接触する。【選択図】 図２
