That was the point as to why your Hulk example was not realistic to the real situation [in which a tractor is centered between its support points - wheel/wheel.] It was not centered for Hulk. Ref 2nd quote above.
Again : Extending support points increases bearing load because the extended support points exert more leverage on the bearing pair.
So the tractor bearing locations got wider in addition to gaining weight :confused2:
