To improve uneven wear resistance property in a tread pattern having an inclined main groove.SOLUTION: In a tire, first and second tread pattern parts P1, P2 arranged in one side and another side of the tire equator have a point symmetrical relationship. Each of the first and second tread pattern parts P1, P2 includes an inclined main groove 4 in which a shoulder main groove 3 is connected with an outer end part 4a, and the inclined main groove extends toward a tire equator C while being inclined with respect to the tire circumferential direction, and terminates with an inner end part 4b not crossing with the tire equator C. A center sipe 5 having a shallow bottom part 15 and a deep bottom part 16 passes through between the inclined main groove 4 of the first tread pattern part P1 and the inclined main groove 4 of the second tread pattern part P2.SELECTED DRAWING: Figure 2 【課題】 傾斜主溝を有するトレッドパターンにおいて、耐偏摩耗性を向上させる。【解決手段】 タイヤ赤道の一方側、他方側に配される第１、第２のトレッドパターン部Ｐ１、Ｐ２が点対称の関係を有するタイヤであって、第１、第２のトレッドパターン部Ｐ１、Ｐ２は、それぞれ、ショルダ主溝３に外端部４ａが接続し、かつタイヤ周方向に対して傾斜しながらタイヤ赤道Ｃに向かってのびるとともに、内端部４ｂがタイヤ赤道Ｃに交わることなく途切れる傾斜主溝４を具える。第１のトレッドパターン部Ｐ１の傾斜主溝４と、第２のトレッドパターン部Ｐ２の傾斜主溝４との間が、浅底部１５と深底部１６とを有するセンタサイプ５によって貫通される。【選択図】図２
