Anyone have any experience or first hand knowledge of how to determine whether it is safe to run slicks that have been sitting...for years.........my instinct says if they pass a visual inspection they should be fine, but that is just my common sense opinion. I now many will say just buy new and be on the safe side, but I plan on changing the rear housing and running a much narrower tire in the future and would rather not spend the $850+ for new tires and tubes just to run a half dozen events this year. I am buying new front tires and they have very slight weatherchecking on the sidewalls, but the slicks appear to be fine.
