Not quite ... after switching to 215/45-17 tires on 8x17 rims, my 200q's
fuel mileage dropped by 20-25 miles per tankful. Top speed has probably
suffered slightly as well but I haven't had reason to check this lately.

It depends upon the offset of the wheels ... mine don't rub anywhere!  (Of
course, since I plan to go with a 235/40-17 when I replace them shortly --
believe it or not, but I've put almost 30k on a set of BFG Comp T/A ZRs,
which isn't too bad for a "performance" tire! -- metal will probably have to
be moved...)
