Abstract

1,024,836. Pneumatic tyres. DUNLOP RUBBER CO. Ltd. Feb. 18, 1963 [March 9, 1961], No. 9075/62. Heading B7C. A pneumatic tyre for a two-wheeled vehicle comprises a tread 7 having a rounded apex centre portion 8 and adjacent side portions 9 which, in the transverse cross-section of the tyre and the uninflated state, are radially inwardly divergent and substantially linear, and a carcass having at least one reinforcing ply 2 of rubberized parallel cords, the carcass consisting of a radially outer portion having an apex 4 and adjacent side portions 5 provided with substantially the same contour as that of the tread 7, and two radially inner portions which extend axially outwardly in a radially outward direction, one from each bead region of the tyre. The side portions 9 extend radially inwardly at an angle of 25 to 55 degrees to a radial line. The tread pattern on each side portion 9 comprises a circumferentially extending zig-zag groove 10a, each straight portion 10b of which is disposed at an angle of 10 to 40 degrees to a circumferentially extending line to prevent sideways skidding when cornering. The tyre may be provided, between the carcass and at least the side portions 9 of the tread, with a breaker ply or plies, the cords of which are disposed at an angle of 20 degrees to a circumferential line of the tyre. When the tyre is inflated the side portions of the tread and the carcass retain their substantially linear form in cross-section so that when the vehicle to which the tyres are fitted heels over on cornering, the tread surface area which makes contact with the road is greater than the area which makes contact when running in a straight line. The tyre is assembled on a cylindrical drum and then shaped in a mould having the appropriate profile. Alternatively, the tyre may be assembled on a former having a crosssectional shape substantially the same as the internal cross-sectional shape of the tyre described.
