Abstract

755,137. Tyre treads. FIRESTONE TIRE & RUBBER CO. April 29, 1954 [Aug. 21, 1953], No. 12433/54. Class 144 (2). A tyre tread comprises a pair of circumferential parallel zig-zag crown ribs 13, 14, defining a zig-zag groove 17, which are flanked on each side by a series of circumferentially-spaced generally transverse bars 15 or 16 which are inclined to the central plane of the tyre and to the bars of the opposite series so that all the bars are directed in the same circumferential direction to provide a directional tyre. As shown, the ribs 13 and 14 are broken by narrow transverse grooves 18 at the apices nearest the centre line of the tread to form a relatively staggered mutually facing chevron arrangement, the ribs being interconnected at each bend by braces 20 which extend radially from the base of groove 17 to half the rib height, and transversely into the adjacent groove 18. The combined circumferential length of the braces 20 is twenty per cent of the total length of groove 17. The shoulder bars 15, 16 are arcuately inclined from the tread shoulders to adjacent the ribs 13, 14 to which they are attached, across narrow grooves 23, 24, by braces 25, 26 respectively rising from the bottom of the narrow grooves to half the rib and bar height. To provide for uniform vulcanization of the large shoulder-bars 15, 16, and to reduce shock transmission thereby, deep narrow grooves 28 extend into the bars from their axially outer ends to terminate just short of their axially inner ends. The bars 15, 16, which are high at the tyre shoulders, define between adjacent bars and the intervening rib portions valleys 27 that open to the side of the tyre. To reduce noise in use, the bars 15, 16 may be of different circumferential lengths and spacings transversely and circumferentially of the tyre. To avoid trapping of stones in the groove 17, the sides of the groove may each comprise two radially inclined surfaces, converging upon the opposite corresponding surfaces, as shown in Fig. 6.
