While the wheel dynamics allow the wheels to move sideways easily, the landing gear dynamics does not allow the landing gear to move sideways (easily).
So apart from the the individual wheel dynamics we also need to calculate the dynamics of the complete landing gear. The resulting forces and moments should origin from the point exactly in between the horizontal and vertical location of all wheels.
Each tire (bogey, in the case of JSBSim) has a reaction with the ground, which causes it to apply a force and moment to the aircraft about the CG.
Now the resulting moments and forces should be added by the results of the individual wheels, not by averaging it, but rather by vector mathematics.

Yes, JSBSim applies the contribution of each wheel to the aircraft CG (force and moment), vectorially.
