why are american school busses’ back tire built like that

I just watched a quiet place: day 1 and realized the bus looked like school busses I usually found while watching american shows. Why are the rear tires of the bus designed too far to the center hence the bus looks unbalanced?

All of the supposed “technical” answer are wrong…..

Buses are built like that because the chassis is a common chassis found on millions of “mid sized” box and utility trucks. The wheelbase is the same. The wheel base is common because of economics as well as DOT rules that dictate the maximum size of a truck that can be driven without a CDL license (under some conditions).

Sure, convenient that the wheel base allows for shorter turn radius, etc. etc…. But that’s not the real reason. They stick a longer body on that chassis for school busses because it’s mainly a shell and even a fully loaded school bus is well under the axle capacity of the chassis.
