The 4 different wheel route will require a pair of 5 on 4 to 5 on 4.5 adapters at the rear ( 60 dollars @ ebay ) and a total of 20 new lug nuts, a different spare wheel and a different lug wrench. Carry 2 lug wrenches or a 4 way incase you should need to get one of the adapters off on the side of the road. I know, everyone carries a cell phone and a AAA card today except me.
