Abstract

PURPOSE:To improve wet skid resistance of a pneumatic tire by providing same with a deep cut extending in the direction of an oblique groove and with a branch groove extending from the middle of each block half section to the respective oblique groove. CONSTITUTION:Each block 6 is provided with a deep cut 8 extending in the direction of an oblique groove 4 to divide the block 6 into two sections along the circumferential direction of the tread 1, and branch grooves 10 each extending from the middle of the surface of the block half section 6a, 6b to the respective oblique groove 4. The cut 8 has a depth substantially equal to the depth of the oblique groove 4 in order to facilitate movement of the block half sections towards the respective oblique grooves 4 within the ground contact surface, such movement causing water collected in the oblique groove 4 to be discharged therefrom towards circumferentially extending linear grooves 2, 3. The branch groove 10 of each block half section 6a, 6b has a width substantially equal to the width of the groove 4 whereby a water film on which a ground contact area of the tread 1 has run is appropriately broken so that the water is expelled from the groove 4 towards the circumferential grooves 2, 3.
