Why fighting tanks have caterpillar wheels ?
Answers
Answer:
There are two factors to determining the mobility of a vehicle in rough terrain. These are the wheel size and the ground pressure of the wheels.
The wheel size enables a vehicle to drive over large obstacles. The larger the wheel is, the larger the obstacle it can traverse. For example, skateboard wheels will snag on small cracks in the sidewalk that a bicycle would skip over effortlessly. To be specific, the size of the lower front quarter of the tire is what matters.
The form of the tracks’ front resembles the curve of a giant wheel’s lower front quarter. This is done by spreading the “tire” or track surface over several wheels. This means tanks can traverse over rocks or hills where vehicles with car wheels could not go.
The tracks also distribute the pressure the vehicle exerts on the ground (ground pressure) of the vehicle over a very wide surface. Ground pressure = weight / surface area of tires/tracks/feet. For example, a soldier with his gear weighs about 200 pounds. Dividing his weight by the surface area of his boots’ soles yields a pressure of about 16 PSI. An armored vehicle, though weighing many, many, times more, can have a ground pressure of only 15 PSI.
In other words, vehicle would drive across ground where an infantryman’s legs would sink into the ground.
While tracks give a huge surface area to distribute the ground pressure, only a tiny part of a wheeled vehicle’s tires count towards its surface area, about the size of a human’s feet. Thus a wheeled vehicle is a pretty bad design for traversing soft ground, feet are okay, but tracks are excellent.

Answer:
because they have to move with great mass and because of heavy body the tanks could sink in sand or land si the caterpillar wheels provide a large surface area preventing the tank to sink
