Twenty wheels connectd to the tracks.
Usually the back wheels are the ones connected to the engine, providing the power to rotate the tracks, and these are the drive wheels. The rest are bogey wheels.
The tank tracks allows the very heavy tank to move over uneven and soft ground. The tracks spreads the weight of the tank over a longer distance. Ground that wheeled vehicles would soon become bogged down and unable to move forward.
Tracks on tanks showed up in ww1 to allow them to cross trenches without getting stuck, America was the first to deploy them.
The weight of the tank is distributed over a large area, exerting less pressure on the ground. Hence, the army tanks run on tracks.
Wheels might get shot out and tracks make it easier for the tank to go over rough land
