PROBLEM TO BE SOLVED: To provide a pneumatic tire improved in steering stability on a dry road surface, wet performance and on-snow performance with good balance.SOLUTION: The pneumatic tire does not have a circumferential groove extending continuously along a tire circumference direction at a tread part 2. In the tread part 2 are provided a plurality of inclined main grooves 3 extending obliquely from a tread end Te toward a tire equator. The inclined main grooves 3 include an outer part 6 which extends from the tread end Te to a position just before the tire equator while increasing gradually angles relative to a tire shaft direction and an inner part 7 which is continuous to the outer part 6 and crosses the tire equator at an angle smaller than the angle of the outer part 6, relative to the tire shaft direction.SELECTED DRAWING: Figure 1 【課題】ドライ路面での操縦安定性、ウェット性能、及び、雪上性能をバランス良く向上させた空気入りタイヤを提供する。【解決手段】トレッド部２に、タイヤ周方向に沿って連続してのびる周方向溝を具えない空気入りタイヤである。トレッド部２には、トレッド端Ｔｅからタイヤ赤道側に向かって斜めにのびる複数の傾斜主溝３が設けられる。傾斜主溝３は、トレッド端Ｔｅからタイヤ赤道の手前までタイヤ軸方向に対する角度を漸増させてのびる外側部６と、外側部６に連なり、かつ、タイヤ軸方向に対して前記外側部６よりも小さい角度でタイヤ赤道を横切る内側部７とを含む。【選択図】図１
