Why do 18 wheelers have 16 wheels?

The extra axle spreads the weight of heavy loads to comply with road regulations. This is the wheel arrangement on an 18 wheeler: 10 wheels on the tractor, and 8 on the trailer. 16 of the wheels are set up as dual wheels to better distribute the weight of the truck.

Why do American trucks have so many wheels?

Why do American trucks have extra wheels?

The simplest explanation is that the more axles a truck has, the more weight it can carry. Plus, of course, more tires in use means more tires to replace, and big truck tires aren’t cheap.
