Although this reply is not directly related to Dyna tire fitment, I believe this info might be useful for those considering the Michelin Commander II (and potentially upgrading one size in the rear tire).
I ride a 2003 RoadGlide with the following spec's.
-SE Air Cleaner andBreather Kit P/N 29440-99B
-SE 1550 Big BoreCylinders P/N 16546-99 or 16549-99
-SE 1550 Flat TopPistons P/N 22851-99A
-SE 203 Cams P/N25937-99B
-SE PerformanceHeads P/N 16952-99A
-Rinehart True DualExhaust
...Not an overly hot bike, but has a fair amount of power and suits my sometimes aggressive riding very well.
Ever since the stock Dunlops wore out I have been using Metzler ME880's ( Stock 130/90/16 Frt. and [one over stock] size 140/90/16 Rear).Make no mistake - they're great tires and handle and stop extremely well in the southwestern Colorado mountains where I live. Only problem with them is that they just don't last (at least the rear anyway - am lucky to get 6K out of therear before it becomes potentially dangerous).
Anyway - after reading numerous reviews on the MC II Ithought I'd give them a try. Went with the stock size in the front and the same one over (i.e. 140/90/16 in the rear). To that end I have to respectfully disagree with the previous post that indicated the MC II's run narrow - whereas I could fit a ME880 @ 140/90/16 inthe rear of my bike (to be sure I had to remove the belt guard curtain but it did fit with a couple of millimeters of clearance) the MC II @ 140/90/16 did not fit as there is a significant amount of belt rubbing on the edge of the tire. Some have suggested you can shim out the rear pulley to compensate, that's not something I wanted to do. Essentially, from my experience the MC II's are a bit fatter at the outer edge so I had to go with the stock size on my RoadGlide.
All that not withstanding - the MC II's are a great tire -handling is great and you can throw a big touring Harley into a "slow to 45" curve at well over 60 mph and they will stick with virtually no lateral flex or unnerving handling characteristics. After a couple of thousand miles they're holding up well and am fairly certain I'll get at least 10 - 12K out of my rear tire(far better than the ME880). My only issue is that even though it's only a slightly smaller footprint in the rear, the bike will get a little loose in the back end if you hit the rear brakes hard.
So - just thought I'd post for those of you considering going with 140/90/16 MC II on the rear of your FLT - it won't fit properly. I found out the hard way and hope I save you some grief if you're considering it.
