Zusammenfassung:	To reduce the rolling resistance.SOLUTION: The tire includes four zigzag circumferential grooves 3 and a space between the adjacent zigzag circumferential grooves 3, 3 is partitioned into hexagonal blocks 5 by a lateral groove 4. Each zigzag circumferential groove 3 includes a pair of center circumferential grooves 6 with a groove width of 4.0 mm or less and a pair of shoulder circumferential grooves 7 having a groove width wider than that of the center circumferential groove. A depth D1 of the lateral groove 4 is smaller than a depth D0 of the zigzag circumferential groove 3 and a first sipe 11 is provided in a groove bottom 10 of the lateral groove 4.SELECTED DRAWING: Figure 3 【課題】転がり抵抗を低減させる。【解決手段】４本のジグザグ周方向溝３を含み、かつ隣り合うジグザグ周方向溝３、３間が横溝４により六角形ブロック５に区分される。ジグザグ周方向溝３は、溝幅４．０mm以下の一対のセンター周方向溝６と、それより幅広の一対のショルダー周方向溝７とを具える。横溝４の深さＤ１は、ジグザグ周方向溝３の深さＤ０よりも小、横溝４の溝底１０に第１のサイプ１１が設けられる。【選択図】図３
