Have you ever wondered why tanks use sprocket wheels and not rubber tires like most cars? The answer is weight and terrain. Modern battle tanks can weigh up to 70 tons, and with rubber tires, the pressure is concentrated in small spots, making it easy to sink in mud, sand, or snow. The use of sprocket wheels distributes the weight of the tank over a larger area, resulting in much less stress. As a result, the tank can travel steadily over soft terrain without sinking. In addition, chain wheels provide much better grip on rough terrain, from rocks to mud. And structurally, chains are much tougher than rubber tires. They don't tear, puncture, or damage easily, even when hit by shrapnel or mines.
