There are only 3 reasons why it would make a difference. 1) Mass 2) Aerodynamics 3) Rolling Resistance.
Are you sure the 4 lug Prius rims are 15" (I remember them being 14")? If so, are your current tires 15"? If so, you can get LRR tires, so that one's not a difference. As far as aerodynamics, you can always get some aluminum pizza pans (plus, looking at the old style of Prius rims, they don't look all that aero anyhow), so that leaves you with mass. Do you know what your rims weigh now? I have seen the mass of the Prius rims, but don't remember it offhand.
