Spike for motor vehicle tires including out-of-round tip and out-of-round root and upper part in twisted relation

摘要

A spike for the running surface of a motor vehicle tire, especially a snow tire, with, as seen from above, an out-of-round, elongated, plate-like spike root (2, 2a), the greatest extension of which defines a longitudinal axis (7a), and an out-of-round, elongated upper part (4, 5) of the spike, the greatest extension of which defines a longitudinal axis (6a). In order to be enabled to accept even greater forces from below, the spike root (2, 2a) and the upper part (4, 5) of the spike are twisted in relation to each other, so that the longitudinal axis (6a) of the upper part (4, 5) of the spike encloses an angle (15, 15a) varying from zero with the longitudinal axis (7a) of the spike root (2,2a).
