PNEUMATIC TIRE

Both wet weather performance and steering stability performance are achieved. Lateral main grooves (16) formed in a tread (12) extend in a direction intersecting with circumferential main grooves (14) and open onto the circumferential main grooves (14). Water between the tread (12) and a road surface during wet weather running is accordingly discharged through the lateral main grooves (16) to the circumferential main grooves (14). The end portions of the lateral main grooves (16) opening onto the circumferential main groove (14) are provided with intersection portions 18 where first land portions (21) and second land portions (22) adjacent to each other in the tire circumferential direction at a lateral main groove (16) support each other in the tire width direction. The end portions at the circumferential main groove (14) side of the first land portions (21) and the second land portions (22) do not therefore readily tilt over even when a large slip angle is imparted to the tire.
