Abstract
1418171 Pneumatic tyres MICHELIN & CIE COMPAGNIE GENERALE DES ETABS MICHELIN 15 Jan 1973 2119/73 Addition to 1327471 Heading B7C A pneumatic tyre for use on roads covered with snow or ice, has a tread which comprises a central circumferential rib 1, two lateral circumferential ribs 14, 7, and two circumferential grooves 5, 6, each circumferential rib being formed by upstanding blocks, e.g. the blocks 2, 12, 15, 16, and having transverse grooves, e.g. the grooves 4, 10, 11, 17, extending into the circumferential ribs from the circumferential grooves, the transverse grooves being less deep than the circumferential grooves, and at least some transverse grooves extending completely across their respective lateral circumferential ribs. As shown, the circumferential grooves 5, 6 are of zig-zag form. The blocks 2 of the central circumferential rib 1 are separated by zig-zag cuts 2a and support one another. The transverse grooves 4 do not extend completely across the blocks 2 but leave uninterrupted portions 3. The blocks 12 of the lateral circumferential rib 7 are separated by transverse grooves 11; the blocks 12 are provided with transverse grooves 10 and recesses 13 for anti-skid spikes. The blocks 15, 16 of the lateral circumferential rib 14 are separated by transverse grooves 17 and provided with recesses 18 for anti-skid spikes. Some of the blocks 15, 16 may be provided with grooves similar to the grooves 10 in the blocks 12.
