ABSTRACT The present invention relates to a vehicle track intended to be driven over toothed wheels and be supported on supporting wheels, which track comprises longitudinal traction members, which are formed of the same piece of an elastomer material and extend in spaced parallel relationship to each other, and transverse carrying members, which are located on the outside oF the vehicle track and connect the longitudinal traction members,which longitudinal traction members and which carrying members have cast-in reinforcements, and the reinforcement of each carrying members consists of a beam of metal with substantially U-shaped section cast-in in the carrying member, the legs of said section facing outward and the section having a height smaller than the height of the carrying member. At vehicle tracks of this kind and provided with two rows of tooth spaces fatigue fractures have occurred, for an unexplain- able reason, in the transverse beams at driving especially on snowless ground. In order to eliminate this disadvantage, it is proposed according to this invention that the guide tongues are positioned on the outer traction members adjacent the tooth spaces, and that the carrying members at least in the area directly in front of the guide tongues are given a greater height than in the area between the same.
