An endless track structure for a vehicle has opposed side edge regions which are elastic and capable of stretching and contracting. When not mounted on the vehicle, the opposed side edge regions of the endless track structure, in their unstressed condition, have a length shorter than their length when the endless track is mounted on a pair of opposed end rolls of the vehicle. Thus, when mounted on the vehicle the opposed side edge regions of the endless track are stretched to a given degree so as to have an initial prestress therein. Thus, when the vehicle executes a turn, the endless track structure will automatically contract at the inside of the turn while becoming stretched to a greater degree at the outside of the turn. |
