Thanks. I have one with about 2-2 1/2-32's left. I know it will be time to re-tire soon, but it isn't quite to the bars. Sort of splitting hairs, and I don't mind throwing away marginal rubber, just wasn't sure what I had left.
I have no idea how many miles are on it. I guess I will take my own advice. I had to ask, so the time is now. LOL
