Abstract
A vehicle drive includes pneumatic tires mounted on rims and includes a track which is engaged by and cooperates with the tires. Tire-supporting elements on the track position the tires on the track. Also, the tires, on at least the surfaces which come into contact with the tire-supporting elements, have an outer rubber layer which has a high wear resistance and low friction properties and in which 50-100% is butadiene rubber.
