    It does look like you are starting to get separation on the tires. With all those little cracks, I would say yes.

  2. First, take your tire off. Remove all gravel/glass from rubber. Inspect outside AND in. If cut THRU tire is >10 mm, it’s long done. Less than 10 mm can be “patched” w a boot (dollar bill or ups envelope piece can work in a pinch).

    Next look for any casing exposed thru rubber on outside->done if yes.

    Cracks due to dry rot? done.

    My focus is on rubber (not sidewall).

  3. Some tyres have wear indicators on them, usually a couple of little dents in the tire and once they’re gone it’s time to replace.

    Hard to tell wear alone from your video but you have quite a few slices/gashes that don’t look healthy.

  4. Some pictures would be better than a video for this. I appreciate that you wanted to rotate it around but multiple pictures would have been better.

    What I’m seeing is either the threads or dirt/dust. Too blurry to tell. If threads, yes, that tire is cooked. If dust, then I see a few spots where the tire has taken some damage but nothing out of the ordinary

  5. There are three major reasons I change my bicycle tires.

    1 – I’m no longer getting the traction/ride from the tires that I want

    2 – I’m getting an excessive amount of flats out of the tires compared to normal

    3 – I can see the chords or underlying structural components of the tire.
