Pneumatic tire

The invention provides a pneumatic tire that may improve on-dry steering stability, wet grip performance and on-snow performance in good balance. The pneumatic tire includes a tread portion (2) which does not have a circumferential groove continuously extending in a tire circumferential direction. The tread portion (2) is provided with a plurality of inclined main grooves (3) extending beyond the tire equator from a tread edge (Te). Each of the inclined main grooves (3) includes an outer portion (6) and an inner portion (7); the outer portion (6) extends from the tread edge (Te) without reaching the tire equator while increasing an angle relative to an axial direction of the tire; and the inner portion (7) is connected to the outer portion (6) and traverses the tire equator at a smaller angle relative to the axial direction of the tire than the angle of the outer portion (6). 本发明提供种均衡良好地提高干燥路面上的操纵稳定性、湿路性能、以及雪上性能的充气轮胎。该充气轮胎是在胎面部(2)不具有沿轮胎周向连续延伸的周向沟。在胎面部(2)设置有从胎面端(Te)朝向轮胎赤道侧倾斜延伸的多条倾斜主沟(3)。倾斜主沟(3)包括外侧部(6)和内侧部(7)，
