<p>A pneumatic tire simultaneously achieves improved water discharge characteristics and reduced noise. Fundamental water discharge performance is secured by providing a tread (12) with a first circumferential main groove (14), a second circumferential main groove (16), and a third circumferential main groove (18). V-shaped grooves (36) connected to the first circumferential main groove (14) are formed in a second land section (22) in a tread center region, and this secures water discharge characteristics and eliminates high frequency noise. On the other hand, L-shaped grooves (52) connected to the third circumferential main groove (18) are formed in a fourth land section (26) located on the side facing the vehicle, and this secures water discharge characteristics and eliminates high frequency noise. Excellent water discharge and low noise characteristics are simultaneously achieved by positioning the V-shaped grooves (36) on the side opposite the vehicle when the tire is mounted on it and positioning the L-shaped grooves (52) on the vehicle side.</p> |
