Hi James, if you're looking for a dryer weather tyre which is same profile then the Toyo R888R would be the answer, however, a couple of points are I think 8" wide on the front would be the reason for tramlining so I think I would be looking at 6" front 8" rear running 185 and 205 Avon ZZS which is the later development of the CR500 and much better in wet conditions. Lots to consider, best of luck!!
