Kinda the same as clothing.
This tire took just about the same amount of effort to seat. I laid the other tire, 175 on the floor and measured the actual width using a 2x4 and tape. It was actually 178mm.

 

I run 195 60 on my 2011 Roadking and my 2013 flhtc and am going to put one on my 2016 Roadglide. Had 25K on both and still had safe tread when I traded.
Do not know about the tire on the Roadglide yet but see no reason it would not work. Will find out soon. Hell of a lot better ride and wet weather traction with the car tire.
