I need a second set of 17" wheels since I've decided I *must* drive my baby every week, and I don't want to remount tires twice a year. My manual says the rim offset for the front is 55mm and for the rear it has two listings for 48mm and 50mm.
Tirerack has some wheels (17" Sport Edition Cup 3) that look exactly like the ones I have, but the listed offsets are front - 52mm; and rear - 47mm.
Will I need spacers? And is there a way to find out what the actual offsets are on the wheels I already have? Thanks for any advice.
