Abstract

A pneumatic vehicle tire having a single layer radial carcass of steel or a material of similarly high strength. The carcass is anchored by being looped around the bead cores in the beads. The laterally outwardly lying free ends of the carcass layer may extend up to about half the height of the tire side walls. Laterally outwardly, next to the looped around carcass end, between the rim flange and this carcass end, there is provided a bead reinforcer which includes pull-resistant threads or the like which are parallel to one another. The bead reinforcer is slanted with regard to the carcass, preferably extending at an angle of about 15.degree. to 45.degree. to the circumferential direction of the tire. The radially outwardly lying free end of the bead reinforcer has associated therewith a strip which extends parallel to said free end and includes pull-resistant threads or the like which are arranged in a cord layer. These threads are likewise slanted with regard to the circumferential direction of the tire, preferably forming an angle of about 15.degree. to 45.degree. with the circumferential direction, but, with regard to the bead reinforcer, are oppositely slanted, i.e. cross the …
