I know this is a hot topic amongst the vendors on this forum. For a couple years now I've installed my own tires on all of my 8 bikes after I contracted a well known reputable bike shop to install new tires on my 'unobtanium' rims on a rare Italian steed I'm a caretaker of,,,,only to find a chunk of aluminium taken out of the rim. Of course I could have bought the tire up here at 50% more and paid the tire levy to be used for the return of the old tire. At this point, I need to find a place to take used tires, and would consider paying a tire levy to any shop who would take my tires, without whining about where I got the tire.
I've got my fire suit on!
