Abstract
507,254. Pneumatic tyres. MULLER, E. Feb. 26, 1938, No. 6089. Convention date, Feb. 27, 1937. [Class 144 (ii)] The tread of a pneumatic tyre comprises suction cells a in combination with loadsupporting studs and/or ribs d, e, the cell walls being provided at the front and rear ends with closable air passages b, the transverse crosssection of which converges from the centre towards the sides thereof, Fig. 5, and terminates at each side in an acute angle. The cell walls in which the passages are formed may be provided with bulges c, Fig. 5, which project beyond the remaining portion of the tread surface, in order to ensure positive closure of the passages. The passages are also formed with restricted portions l, Fig. 6, between the inlet and outlet orifices. The sectional shape of the passages may be trapezoidal instead of arcuate.
