Abstract

1,237,616. Vehicle tyres. SEMPERIT-A.G. 29 Aug., 1969 [30 Aug., 1968], No. 43035/69. Heading B7C. A pneumatic tyre has a tread pattern comprising circumferential ribs and channels 1-6 with at least the axially outermost ribs being traversed by grooves 11, 12 forming separate blocks 17 and in the as moulded state of the tyre at least the axially inner flank of each of the outermost channels 1, 6 being inclined at an angle a, of 15 to 30 degrees to the tread crosssection radius of curvature at the outermost channels, with the bottom of the channels further from the midcircumferential plane than the mouth of the channels. In the tread pattern disclosed both channels 1, 6 and 2, 5 are inclined at angles α 1 and α 2 respectively, α 1 being preferably from 15 to 25 degrees and α 2 from preferably between 18 to 28 degrees. The axially outer flanks 7, 8 of the channels 1, 6 and 2, 5 are angled at 9, 10 to be parallel in the as moulded state to the midcircumferential plane. The central rib 15 is continuous but the ribs between channels 2 and 3, 4 and 5 are traversed by grooves 13, 14 in a similar manner to the outermost ribs to form blocks 16. The grooves 11, 13 are narrower than the grooves 12, 14 and channels and grooves adjacent the edge of the tread are broader than corresponding channels and grooves located towards the middle of the tread. Channel widths are 1 to 2% of the tread width B<SP>1</SP> and groove widths 0.5 to 3%. To reduce tearing of the blocks angles in the flanks of channels and grooves are rounded off at the channel base.
