Does anyone know how wide a wheel the 2004 RX330 can accommodate? I'm considering replacing the factory rims, 18" x 8.5", with the Leon Hardiritt Lanze Wheels, 19" x 10". Would a 10 inch wide wheel be going to far? I'd like to know as soon as possible before I make the wrong choice. Oh by the way does Leon Hardiritt have a U.S. website? I saw the address posted somewhere here and now I can't seem to find it.
