I have the Anakee II on my F658GS ... roughly 12K miles on them now and they would have been good for another couple thousand I think ... alas ... today I picked up a very small puncture in the rear ... what I pulled out of the tire looked almost like a small shark tooth and was none metallic ... not sure WTF happened...
With the tread "almost" gone, I'm not sure I'll bother trying to repair ... unless someone has a clever suggestion?
Anyway, I like the tires ... good grip nice ... in pretty much anything but slick/wet hard clay
One thing I do notice which I think is a result of the tread grooves getting larger as they get to the edge of the tire is some heavier "road noise" when I have the bike leaned over ... not a big annoyance.
BTW: Does anyone know what the original tread depth is on the Anakee II ???
