    You could patch it from the inside for peace of mind but I’ve found these tyres get tons of these cuts and are mostly harmless just slitting the rubber not harming the material underneath 

  2. Can you see the cords inside? If not, you can carefully make sure there’s no more debris inside the slit and then glue it back with shoe goo or another flexible adhesive. It won’t help with the integrity of the tire, but it will help prevent debris from getting inside.

  3. Did the tube actually get punctured as well? If so, patching from the inside will give you tons more miles on this expensive tire.

    Loctite blue to close it. This glue stays flexible and holds well. Keep a tube on hand for this very thing.

  5. I just put a tpu patch on the inside of the tire with my gp5000s, got a few now and they seem to hold alright.

    It really depends on how wide the cut is on the inside, if it’s only a little pin hole it will be fine. If the tube is exposed then you’ll want to replace it.

    You could do some surgery and try to stitch it from the inside with kevlar thread. It would need to be below the base layer of rubber just above the carcas but few people possess this level of expertise.

    Clean it out to get all the little bits out. If it goes all the way through, clean it out on the inside and then ride it to the threads. It looks fine.

  8. I wouldn’t worry about it. I’ve been riding these tires for like ten years (about 2000 miles per set) and they always get little cuts like that. Doesn’t seem to affect the casing or actually lose air.

  9. I usually use good-quality super glue to stick them together. And even though I had a larger cut, it worked very well.

    I have many cuts like these on my road tires. Rubber is sort of “self-closing”, especially if ridden on.

    I would put a drop of my tube cement “glue” there after having cleaned it with a toothbrush and bit of isopropyl alcohol prior. I would not put any patch on the inside, at all.

    Except if the cut is through the “mesh” material, but that’s what tire “boots” are for – but that’s meant more like emergency fix till you can (and probably should) replace it.

  11. The GP5000 AS TR I just replaced had probably ten cuts like this. I likely could have ridden it another 1000 miles had I not gotten new tires on a discount. I don’t think most of these go that deep and the ones that do seem to be plugged up quick by the sealant.

    Patch on the inside, and squeeze a few drops of Gorilla glue into the open cut, good to go.
