Tyres on the way to replace. But would you ride this in the meantime please? Slash appears to go through to the lining of the tyre. Tube patched and tire patched internally and maintaining its pressure. Rear wheel so I guess a potential blowout is unlikely to be too dangerous versus if it was front wheel. Thanks

    1. if it’s a temporary repair, I would take the pressure out and use some type of butyl glue to place the cut. pump it back up after.

    2. If by temporarily you mean slowly to the bike shop at the end of the street to get a new tyre…. Then yes.

      Besides the cut, the tyre is dry rotten, I doubt it provides any grip.

      I’ve ridden with a bank-note lining inside a tyre for 50 miles after the side-wall split with a bang. To be honest, it felt perfectly fine with the note in place.

    4. I’d compare it to a boba tea blind taste test. As soon as it pops you know what’s up.

    5. Internal (butyl) patches help but they’re too elastic, so don’t add structural reinforcement to the tire’s carcass like a boot does. So I’d add that. Don’t know where the OP lives but here, in Canada, we have polymer notes, not paper, and they work very well as boots. Fold a fiver, position between tube and damage, and inflate. I’d ride that tire as long the plies’ threads are not breaking and there’s no conspicuous bulge.

    6. Zoom in and look at the raised line above the P, you can see deformation, don’t ride this!

    7. Aside from reinforcing it from inside, is there a product that would allow you to fill in that gouge, at its inflated state?

      Some sort of liquid rubber that you can stuff in it, and shave off with a blade, once it’s hardened?

    8. Put a boot in and it will be fine. The cut is small enough the tube should not bulge or anything.

      If you were stuck out in the boonies and needed to get home, then yes, especially with a patch. But if you don’t need to ride, I wouldn’t. It’s just not worth the risk.

    10. Repair with superglue and ride until it’s worn out. Anyone telling you to replace this tire is a bike industry plant or has never ridden fixed gear.

      I’ve ridden a tyre with a sidewall cut like that for hundreds of kilometers without any issue. Used a Park Tool TB-2 tyre boot though (much tougher, thicker and bigger than an inner tube patch).

      Tire has a bulge = don’t ride it.

      If you’re stuck in the boonies, then boot it to get home or to the nearest bike shop for a replacement.
