I am hoping someone has this tire installed on their Cross Bones or Night train or something similar, and can tell me the true mounted width of the thing....

I just got off the phone with a Michelin customer service rep; I am wondering how wide this tire actually is once mounted. I was told it is 8.66" wide, or 219 millimeters, which is what they said was the running, expanded width of the tire while in use. This seems strange because everywhere else I read other sizes of these tires are a bit more narrow than other brands.

This is also what I was told via email:

"Actually 8.66" (220 mm) is the overall width of the tire when in use
When you are riding your motorcycle, the tires become a little bit wider and there is an increase in the width and diameter.

The mounted overall width of the Commander II 200/55R17, is 7.87" or 200 mm"

I don't believe that a tire like that would expand 19 mm or about 10% of its width. Am I crazy?

 

Doesn't sound right to me either. I know a lot of people run that tire on their softails so even if it is accurate it's not a problem.

 

I'm wanting to run it on my Wide Glide with a 6" wide wheel.

Would anyone with one care to take a width measurement for me? I want to make sure it will fit inside my fender....

 

I will once I get home... Where would you like the measurement from?

 

Widest point to widest point is what I am looking for, should be around 8"s.
Would be very much appreciated! Despite their effort, Michelin wasn't much help.

PS: what width rim do you have it mounted on?

Thanks!

 

Mine is 8 1/16" on a 6" Fatboy rim.

 

i run that on my 07 FB. it measures 8" exactly with 42 psi in the tire on a 6" rim sitting on the kickstand. i measured at approx the bottom 1/3 of the tire. as far up as i could go until my straight edges hit the belt/sprocket on the left side.

 

A tire is not going to to grow width wise, but on the contrary height wise and will become a tiny bit narrower at speed. As far as the width mounted on teh wheel I have no idea but I have put the Com II's on several fatboys (07 and newer) locally without issue.

 

17" X 6" slotted disc cast aluminum wheel and my tire measures approx 8.25"

 

Thanks a lot guys this is exactly what I was looking for! As long as its 8.25 or under I'm good, thanks for the real-world measurement.
