1,226,325. Pneumatic tyres. DUNLOP CO. Ltd. 5 April, 1968 [8 April, 1967], No. 16196/67. Heading B7C. A pneumatic tyre has at least one shoulder 3 provided with a plurality of wedge-shaped elements 2 having faces 6 disposed in such a way that they will be engaged by water associated with a surface over which the tyre is to run to tend to decrease the velocity of the tread 5 relative to the surface during movement of the tyre upon the wet surface. The wedge-shaped elements, which may be attached to or integral with the tyre, may be either in the form of solid blocks or pockets, Figs. 12-15 (not shown). In the latter case, the faces are formed on interior surfaces of the pockets. The pockets may be open at the end remote from the entry portion. Both blocks and pockets may be reinforced by one or more layers of rubberized cord fabric. |
