Abstract
Abstract A puncture proof vehicle tire comprising two symmetrical halves mounted on a divided felly, wherein the tread and the foot of each tire half are connected by a resilient, reinforcing connecting portion which comprises a plurality of supporting members having been formed by axial cut-outs. It is preferred to arrange the axial cut-outs in such a way, that the supporting members of the connecting portion are segment-like and alternately arranged in opposite directions and thus in successive segments are orientated alternately towards the felly edge and the felly center.
