Tire damage? Aesthetic or worse?

Notices
Cyclocross and Gravelbiking (Recreational) This has to be the most physically intense sport ever invented. It's high speed bicycle racing on a short off road course or riding the off pavement rides on gravel like : "Unbround Gravel". We also have a dedicated Racing forum for the Cyclocross Hard Core Racers.

Tire damage? Aesthetic or worse?

The title says it all - is this something I should worry about? Holds air (tubeless) & doesn't affect handling.

I've seen worse, had worse, and ridden worse. If it'll make you feel better, put some glue in it.

Or a small patch on the inside.

Thanks. This makes me feel better. I am really enjoying these "slick" tires, but it seems as though they may not be enjoying the terrain I ride in. The thought of having to replace a tire at 250 miles had me second guessing the move to a slick tire for gravel.

Is it down to the cords? Personally I would chalk it up to bad luck, swap it out and move on.

No sense in heading out for a ride with a known liability. I prefer to do my bicycle repairs and maintenance at home rather than while out riding.

I have had similar results from my road bike tires. Seems like as soon as I put a new tire on I get a puncture of some sort within the first few hundred miles. I have a plug in my front tire that has been there for over 2000 miles. The plug in my recently replaced rear tire lasted less than 100 miles before I needed to pull it off and patch it.

I wouldn't ride that, chalk it up as a loss - happens to all of us sometimes.

If there is damage to the cords, or the cords are showing, you should throw it out.

Reading stories about people who go for a bike ride and then wake up on a LifeFlight helicopter help me realize how important tires are (post crash analysis reveled he had a blowout)

I would pull the stick out, patch from the inside and then make sure this is only a back tire from now on. Better would be to replace and forget about.

No stick. There is a chunk of tread missing. To be more specific, the tread & first layer of rubber is missing down to the first layer of threads. The threads appear to be intact. I find the vastly different answers to my question to be amusing. I just recently went tubeless and I am still learning. The ride that is responsible for this had about a 1 mile section of large & sharp rocks. These rocks just may have been too much for the slick tires that I love so much. I am going to keep a close eye on these tires and I move to something that is a little more resilient if I have to.

I think filling it with glue/shoe goo or something, putting a patch behind it, and running it in the rear would be pretty darn solid.

That is pretty far towards the sidewall, for better or worse. At least one isn't pounding on it in center-tread.

I'm with @TXBDan. Patch or something on the inside.

You may be able to get a patch to stick to the outside, or fill with some rubber compound. I haven't been thrilled with shoe goo (other projects). It works for some things, but not necessarily stable for long-term use.

Yeah, it is kind of up to you, how much pressure you put in the tire, how much you like it. If it is a $10 tire, replace it. If its high end and you love it (and since it is relatively new), you can still ride it - although keep an eye on it. I've put a tube patch on the inside of a tire before, but if you are running tubless, you in essence have a light patch on the inside of the tire anyway.

Any damage visible to the inside of the tire (probably can't tell since its tubeless). The integrity of the tire depends on the damage to the chords and the carcass. If its just rubber (not cord/carcass) there isn't much wrong with it.

I feel the same way about my Pari-Motos, which are very similar tires. I love the ride, but there isn't much tread for protection.

I got these cuts from running over some broken glass on Saturday. Put some patches on the inside of the nearly new tire (that orange color is the underside of a patch) and have ridden another 150 miles. I have another one ordered, but I'll ride this one on a 400k on Saturday if the replacement doesn't arrive by then.

Yes, and as I am sure you have figured out, these tires have sold me on the concept of no knobbies for all surface riding. Super fast on the tarmac while being extremely capable when you leave the tarmac.

As for the damage, I would say it is more like 5-6 mm with 2 mm of cords showing. I have put close to 100 miles on it since the damage, with about 25% of that being dirt, gravel, crushed limestone, mud, etc., with no issue at all. I always carry plugs with me, so I am just going to ride it out at this point. Based on the scuffing on the sidewall, I am going to say that this was a fluke, and that the tire is fairly resilient.
