Your logic pnichols would apply to solid wheels, while pneumatic tires do flex and flex quite a bit.
Not the best pictures, but this is what I could find on the net.
Side flex can be huge. Obviously stiff truck tires, especially low profile will have it less, but still.
Bottom line, European heavy trucks drive on 4 or 5 axles just fine and tandem seems to be well more common than side duallies.

Tires can also flex a bit radius-wise, but that comes with big forces.
Don't expect such flex from truck tires.
