Abstract

A pneumatic vehicle tire which has fine slits in the tread. These slits are inclined relative to the circumferential direction of the tire. In order to increase the frictional connection to the roadway, to make the wear of the tread more uniform, and in addition to be able to use mechanically stiff plates for the associated vulcanization molds, the fine slits are twisted about an at least approximately radially extending twist axis. The fine slits preferably extend continuously from their roots into the tread surface region proper.
