My preferred tyre for these larger Tourers is defiantly the American Elite, I even fitted a set to the Fatboy.
I know Mickle runs the Dunlop Americana Elite, and thats what I got on rear of my FXST, good in all weather. , I also have the Michellin Comander 2 on front and happy with it, Last front M-C-2 I get just over 21000km
