Abstract: A pneumatic drive sprocket for tracked vehicles which includes a belted radial tire casing having radially projecting lugs or teeth disposed in spaced-apart relationship about the circumference of the tire and which are adapted to engage the track for driving purposes. The utilization of such a drive sprocket enables the vehicle to obtain the shock absorbing and flotation characteristics of pneumatic tires while permitting accurate, consistent and positive driving engagement with the track due to the fact that the pitch length between the teeth is not appreciably changed upon contact with the ground because of the essentially circumferentially inextensible nature of the radial belted tire.
