I, or the previous owner of my bike, have never changed the tires on it. I'd imagine they're years old. That being said, there is still a huge amount of tread on them and no dry rot. The bike handles fine. Am I in any imminent danger riding on old tires? I understand new tires are better, but I'm in a tight spot financially and only really riding it 10 or 20 miles at a time. Like I said, the tires have a whole lot of tread left on them and there's no dry rot.
