Replaced my stock dunlops at 22K with Metzlers 888.
I've got about 10k on the Dunlops and they're cupped badly; same as all of the previous Dunlops on the FLHRSE5. Admittedly, I'm hard on tires and don't mind getting 10k except when the last 1k - 2k is plagued by the sound and feel of a cupped tire.
Thought about the Michelins as I run Pilot Sports on my R1100S and they are really a great handling tire in all weather conditions. But, 5k is even a stretch on the Pilots + sportbike.
Anyway, I've also been using the Metzler 880's on my Wide Glide and really thought it was a good tire. Mileage wasn't great but we put most of the miles on riding two up with luggage.
So, faced with the decision to fit the Michelin Commander II's and the Metzler 888's, I went with the Metzlers. If those wear-out in less than 10k or exhibit crappy wet road handling I'll give the Michelin's a try next.
