I will be replacing the original tires on my 2010 Wing soon. I just ordered a set of Avon Cobra's, plus am going to have front Centramatic installed, possibly the rear also. The dealer told me that the Centramatic on the front tire is a must, but not on the rear. I ordered the new Avon's from DLP, however, they have not arrived yet. I will report my opinion after a few thousand miles.
