To provide a pneumatic tire of which snow performance can be improved while suppressing decrease in a block rigidity.SOLUTION: Plural lug grooves 21 having a sharp bent part 22, and plural sipes 11B, which extend in a direction intersecting these lug grooves 21, are provided on an intermediate land part 10B. Respective lug grooves 21 are so located as to be not overlapped on one another in a tire circumferential direction in such a manner that one end 21a of each lug groove is opened to an outer side main groove 9B, and on the other hand, the other end 21b thereof is terminated in the intermediate land part 10B. When dividing pitches p1 to p5 with an end point 23 of the lug groove 21, which is opened to the outer side main groove 9B, as a reference position, each sipe 11B is so located as to be accommodated in a single pitch p1 to p5, and a groove area ratio of each pitch p1 to p5 in the intermediate land part 10B falls within a range of 15% to 25%.SELECTED DRAWING: Figure 2
【課題】ブロック剛性の低下を抑制しながら、スノー性能を向上させることを可能にした空気入りタイヤを提供する。【解決手段】中間陸部１０Ｂに、鋭角な屈曲部２２を有する複数本のラグ溝２１と、これらラグ溝２１に対して交差する方向に延在する複数本のサイプ１１Ｂとが設けられ、各ラグ溝２１は、一方の端部２１ａが外側主溝９Ｂに開口する一方で他方の端部２１ｂが中間陸部１０Ｂ内で終端すると共に、タイヤ周方向に互いに重ならずに配置され、ラグ溝２１における外側主溝９Ｂに開口する端点２３を基準位置としてピッチｐ１〜ｐ５を区分したとき、サイプ１１Ｂの各々が単一のピッチｐ１〜ｐ５内に収まるように配置され、中間陸部１０Ｂにおける各ピッチｐ１〜ｐ５の溝面積比率が１５％〜２５％の範囲にある。【選択図】図２
