nmu98, I would alter your statement a bit according to what the tire manufacturers say: for a tire to work right, it has to achieve that maximum contact patch with the ground, consistent with enough inflation pressure to support the axle. If you increase weight on an axle for a given tire pressure, the contact patch will broaden, giving better traction. But you can more efficiently do this by just letting air out of the tire, as long as the pressure will support the load and the rim doesn't slip.
The basic lesson of these tire handbooks is that for best traction: a) get the front-rear axle weight balance correct for the type of tractor one has (2wd, MFWD, or true 4wd), then let the air out of the tires to achieve the minimum that will bear the axle loads.
