I just got over 13,000 miles out of my IRC WildFlare 120/90. By far the most mileage I got from a front tire, the others were Bridgestone and Metzler.
The IRC still had some life left in it, but it was cupping around the tread sides (does that make sense?) and starting to show cracks in it.

Always remember to be yourself. Unless you suck. Then pretend to be someone else.
