Abstract
A vehicle wheel and pneumatic tire arrangement. The tire has a radial carcass anchored in the tire beads, a tread strip, respective shoulder-like extensions which are each formed by a step, are disposed on each side of the tread strip, and do not come into contact with the roadway under normal driving conditions, and a belt which extends laterally to within the vicinity of each step extension to such an extent that a given one of the belt portions which is disposed within the vicinity of a given step extension has a width equal to approximately 25-40% of the amount by which the widest part of the tire extends beyond the end of the tread strip at that given step extension. To achieve a low rolling resistance and at the same time a great travel comfort, the beads of the tire are disposed axially inwardly on the rim to such an extent that the beads are disposed completely axially inwardly of the step extensions. Furthermore, the carcass neutral line essentially conforms to the membrane theory in the region of the sidewalls of the tire.
