If you like the Commander II I would stay with it. I went through 2 sets of Dunlop American Elites on my bike and got over 20,000 on each set, which is very high mileage for me. I have also run the Commander II on another bike and liked them. I currently have a Commander II on my back wheel because I needed a back tire and my local dealer stocks them.
I also have a 2014 Limited and use the Dunlop American Elite. I also got 20K out of my rear as did Gonzo. Used them exclusively on my 08 with basically the same results. Handed well in all weather conditions and are a bit cheaper than the Michelin’s.
I have used both – had a Road Glide Ultra now have Ultra LTD- and I got about 20K miles on both. I liked the ride better on the Michelin’s. I don’t think you can go wrong with either if you take care of them. Check tire pressure often, keep it at recommended level and you will get a lot of “extra” use out of a tire.
