A vehicle drive wheel including a pneumatic tire mounted on a rim is provided with a track driven by the tire. The track comprises tire-supporting elements. At least those portions of the outer surfaces of the tire which come into contact with the inner portions of the tire-supporting elements comprise an outer rubber layer which has a high wear resistance and low-friction properties and 50-100% of the rubber is butadiene rubber. Also, an admixture of natural rubber and/or styrene-butadiene rubber can be added to the outer rubber layer in an amount of from 0 parts by weight of the admixture per part by weight of butadiene rubber to less than one part by weight of the admixture per part by weight of butadiene rubber.
