Why are two slimmer wheels paired on each side of the axle in buses and container carrying vehicles, instead of a single large broader wheel?
In: Engineering
Some dump trucks that frequent quarries use the single broad tires you describe. The benefit to them is the dually tires often pick up a rock between them, and after a few miles of driving, it can ruin both tire sidewalls.
The benefit to duallies is that if one tire goes flat, you can usually still drive a short ways to get to a safer place.
