I found a couple of brand new tires that had been in storage since probably 1995. They were Velociraptors with less that 100 miles on them. Good MTB tires.
I used them for @150 miles, mainly on pavement. I noticed that the outside knobbies were pulling loose. Is that because of the pavement, the age of the tires, both, neither? Should I just trash them at this point?
