ABSTRACT:
A belted tire having a respective step at each of the edges of the tread strip, with the edges of the belt extending to below the approximately horizontal surface of the step. In order to avoid undesirable heat formation, and hence to reduce the rolling resistance, a low-dampening rubber layer is disposed between two belt piles, with the rubber layer ending prior to the edges of the belt. In these regions, as extensions of the intermediate layer, respective additional rubber strips are provided. Half of the width of a given rubber strip is disposed below the belt plies, and the other half of the width of that strip extends laterally beyond the belt. These rubber strips are harder than the low-damping intermediate layer.
