Perhaps, but you would have to know the compliance (mechanical stiffness) of the wheel. The vertical stiffness is not directly driven by the wheel's diameter.

For example: an aluminum AM Performance wheel is probably a lot less compliant than a rubber and plastic Colson wheel. I could see a 6in Performance wheel being stiffer than a 4in Colson wheel, but that is only my intuition.
