Should I replace the tyre or can I keep going? I just noticed a small tear in my Continental GP 4000s. It does not bulge out from the side. The tyre have been on for some years now but dont have more than 1000km on them.
I am worried though if I should change them or if I could keep going with them?


Edit: Thanks for all the answers!
Replacing the tire seems like the best thing to do. Especially since I mostly go greater distances whenever I go out cycling. I have a hard time seeing the damage actually myself, but there is no doubt that some of the structural components of the tire have been damaged.
I would gladly pay €30 (or whatever the tire costs) to decrease the risk of tire failure. After all, going out cycling is supposed to be fun and not to cause feelings of uncertainty.
It's difficult to tell from this picture, but it looks like the casing—the structural part of the tire—has been damaged, so it's just a matter of time before the tire fails completely.
Look at the inside of the tire. If the damage has penetrated all the way through, I would stop riding on that tire. If it hasn't, you might be able to get away with gluing in a &quot;boot&quot; (a small piece of old tire) to reinforce this spot. But based on this picture, I think replacing this tire is the smart thing to do.
