Aires and crew, it would help to define what state of wear is considered worn out by you'all. Racers toss em out after edges over heated and scrubbed off or melted with globs, yet center almost pristine. I considered them worn out when can't trust to hold air over 20 miles or cords showing so more puncture prone to THE Grit. If I changed tires when center grooves gone they'd only last 2000 miles if that. I really do have to pay attention constantly how I ride or would be spending on tires about monthly, in nice seasons. So I really only ever give er much gas except in leans, so yes I tend to relax and coast and lazy weave on the straights where every one else seems to be most nailing it on.
May you all use up even more tires than me a long long time eh.
OK what's the survey on longest lasting tire regardless of condition and sporting glee's? One dual tread long lasting hard 160 Dunlop tire I tired on SV650 was absolutely freaking dangerous on or off road. Did a search to see others being taken down on it too so replaced while still essentially new,ugh. I tired to use it up but was so hindering i gave up about half way through it and shop I took it too made me do a burn out for minutes before it popped and cheering from onlookers in city area. Yet similar tire on Ms Peel allowed the wildest harshest flings I've ever done in my life, yet lasted to use on Trixie break in till tube blow out made me ride it home 6 miles on THE Grit. Its still got decent grooves so didn't toss out yet but pensive I've destroyed its cords and might blow out again at speed, ugh.
