To carry more weight safely.
Elementary my dear Dr Watson, it carries much more weight.. It could have 4 wheels, but such wheels should have to be four huge ones making the truck to run much slower, and the driver would have more difficulty to drive the truck..
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.
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.
They are broader for better traction.
It can have anywhere from four (a small pickup with a dump body) to 22 or more (tractor and end dump trailer with lifting tag axles). For a straight truck in the US, the most wheels you'll get on a vehicle is a configuration which is known as a 'centipede' - it's a straight dump truck (10 wheels) with four lifting tag axles (8 more wheels), for a total of 18 wheels.
more than 15" rims
You have to go to truck dealers

To haul heavy loads, there needs to be more wheels to carry the loads.
The answer is: a garbage truck!The joke is 'What has wheels and flies'.
A vehicle with 18 wheels is commonly known as a "semi-truck" or "tractor-trailer."
a 4x4 truck is a truck that instead of only using power for 2 wheels, it uses power for all 4 wheels instead.
