  1. Yes, that tire absolutely needs replacing. It may be the source of the flats, but even if it isn’t, that tire isn’t safe to use.

  2. The way the casing is frayed out I would double check your brake pads aren’t contacting the tire.

  3. Your tire is really dried out and when rubber dries out, it becomes less resistant, and more accepting also if you can see the threads that are usually inside the tire. That’s a good sign that’s time to replace.

  4. Replace. Have a bike shop check for wear on the rim too. If it had a wear indicator and you can’t see it anymore, it needs to be replaced. It looks like it has some chunks taken out of it too..

    I just wanted to add that you rim looks a bit damaged there are well. I don’t know if this is affecting your brake pads (pushing them out of alignment at this position?) or not holding the tire bead strongly there (causing pads rubbing in the tire in that spot?) I’m not a rim expert, but it might be worth replacing the rim too to avoid having to buy a new tire again as well. Maybe another commenter can say if I am wrong.

  6. Figuring out where your tube was ruptured in relation to the tire should give you a clue as to where the problem was – if it turns out it’s where the tire is damaged, that’s probably it.. You can inflate the tube while still in the tire and listen where the air is leaking. Also, checking the inside of the tire isn’t always enough. I’ve recently had a glass shard stuck in between the ridges on the outside that wasn’t noticable from the inside, which caused me 2 flats before I discovered it.
