Abstract

A motor vehicle pneumatic tire is made of polyurethane or another similar moldable material which hardens into an elastic plastic material and which has a substantially cylindrical or cylindrical belt insert mounted beneath the tread substantially composed of threads, wires or similar stability support elements which are mounted in the circumferential direction of the tire in a spaced-apart manner at a distance of 0.5-3.0 mm and which elements have a cross section of 0.5-2.5 mm. The stability support and the plastic mass of the belt insert encompassing the same having a tensile strength in the circumferential direction of at least 3 Mill.N and the elements of the stability support have a breaking strength of at least 1,500 N.
