Well I finally changed out my front tire on my 2004 xl1200c.
I put a Metzeler 880 MH90-21 with 13,000 miles on the bike last spring. The Bike now has 29,247 miles on it.
I just replaced it with a Michelin Commander II.
I will have to see if it lasts as long as the Metzeler.
Here are a couple of pics of what is left of Metzeler tread.
I know some people would still be riding on it, but I feel better safe than sorry.
Especially when my wife likes riding with me.
