Why do tanks use tracks instead of wheels? Why is there an edge? What's the use?

The tank is equipped with crawler to increase the stress area and reduce the pressure. The contact area between the track and the ground is much larger than that between the wheel and the ground. With the track, you won't get stuck in the mud or swamp. If you walk in mud or swamp, you will sink.

Tracked loaders have better cross-country ability than wheeled loaders, can cross ditches and low walls, and have good climbing ability, which cannot be compared with wheeled loaders. But on the expressway, tanks can't run without wheels, so each has its own advantages! Enhance off-road ability and protective performance. Think about it. The off-road ability of wheeled vehicles is far less than that of tracked vehicles, and the protection performance is not good. Tires are always easier to beat than tracked vehicles.

Always remember, friends, tanks are born with the function of 1. It is very demanding to be attacked by various weapons, from grenades and pistols to howitzer missiles.

1, reducing the wheel pressure on the ground, which is beneficial to increase protection;

2, the terrain is open, which is convenient for field maneuvering;

3. Keep the car body stable and improve the shooting accuracy.

Ordinary tires can't bear the weight of more than 20 tons. Even if they can, they will burst due to inertia at the moment when the tank starts or brakes.
