Being unable to rotate tires on the XFire due to 18" on front and 19's on rear and get rid of annoying tire noise du to no rotation every 10K was thinkig of picking up a set of AMG either 18 or 19" wheels on ebay so I can rotate the tires, every 5K.

First has anyone done this, second as they are MB wheels will they fit the xfire?

Any comments appreciated
