I ran into the same problem. Had Goodyears and then could not get a replacement for rear so went with BFG but when I went to replace fronts no tires available in the correct size for front. Finally went with Dunlops but front tire is 1/2" smaller than original. I figured as long as it is not the rear it does not make the spedometer off. Very agressive tires and the ride is sooooo nice compared to the Goodyears. Just my 3.5 cents worth.
