Why do tanks have tracks instead of wheels?
Tracked vehicles have better mobility than pneumatic tyres over rough terrain. … Tracks are tougher than tyres since they cannot be punctured or torn. Tracks are much less likely to get stuck in soft ground, mud, or snow since they distribute the weight of the vehicle over a larger contact area.
