I think I know the answer, but can't say I like it... but do you think this tire is toast? Yes, that is a nail through the tread. Argh.
Would you think me foolish to plug it and ride? Seems to be holding air but that's just sitting through a Boston winter.
1991 K75S rear tire, one year old, Bridgestone. Maybe 3000 miles on it (I have two bikes)
