A pneumatic tyre comprises a tread portion (12), comprising blocks (6) provided with fine grooves (3) for preventing bareness of rubber, the fine grooves (3) having a depth of 0.2 to 0.7 mm and a width of 0.3 to 1.0 mm. The fine grooves (3) extend from the angularly narrowest corner (7) to a block edge (5) extending substantially in the circumferential direction. The angularly narrowest corner (7) may be provided with a slope (22) having an angle of 30 to 60 degrees to the normal direction to the tread surface. <IMAGE> |
