It's because (a) the more wheels it has, the more weight it can carry, and (b) more wheels means more traction on the road.
A tow truck typically has four wheels, like most standard vehicles. However, the total number of wheels can vary depending on the specific design and configuration of the tow truck, as some larger models may have more wheels to support heavier loads. For example, a heavy-duty tow truck might have six or even more wheels.
A vehicle that can have as many as 18 wheels is a tractor-trailer truck, also known as an 18-wheeler. These trucks typically have 18 wheels, with four wheels on the front axle and dual wheels on each of the two rear axles. The additional wheels help distribute the weight of the cargo more evenly, improve stability, and allow for the transportation of heavy loads over long distances.
