Re: 4" vs. 6" + 8" Diameter Wheels
4" wheels allow you to create a longer wheelbase, since the smaller wheel allows the axles to be spaced apart further.
Additionally, 4" wheels reduce the reduction required from a CIM motor to achieve a reasonable speed. Smaller reductions mean less frictional loss.
They arguably produce faster acceleration, since the wheels have less rotational inertia.
