FAHRZEUGLUFTREIFEN FUER DIE WINTERVERWENDUNG

摘要

The invention is based on tyres of this kind in which the tread consists of four circumferential rows with essentially rectangular blocks extending transversely to the tyre circumferential direction. So that these tyres have an improved grip not only on a soft surface but also on a rigid, snow-covered or ice-covered surface, the blocks located between the circumferential rows which are laterally on the outside are provided on their edges extending transversely to the tyre circumferential direction with fine indents which are intended to form an angle of approximately 15 to 30 with respect to the tyre circumferential direction. The edge parts of the blocks equipped with these fine indents are of zig-zag or undulating shape, the fine indents starting from the wave troughs of these edge parts.
