ABSTRACT:
A pneumatic vehicle tire has a carcass with at least one radial ply and beads having bead cores, whereby the carcass is anchored to the bead cores. A multi-ply belt is positioned radially outwardly on the carcass, and a tread is positioned radially outwardly on the belt. Sidewalls extend between the tread and the beads. The sidewalls have a first portion extending from the beads outwardly at an angle of 0% to 20% relative to the axial direction of the tire. The sidewalls have increased stiffness within the area of 50% to 90% of a tire height measured in a direction from the bead to the tread. The area of 50% to 90% prevents the sidewalls from touching the road surface when the tire is deflated and compressed.
