Not just the overall diameter - also the diameter of the wheel. If the wheels are heavier and larger than stock, the combined wheel+tire+air likely has a significantly higher moment of intertia (the equivalent of mass when you're torquing something to get it spinning) - this is what slows you down.
Plus, wheels are all unsprung mass, although maybe that's not a big deal when driving in a straight line.
