OK. You should see the picture now.

I think it is fine.

I'd run it.

coasting 

no big deal. smaller than on my tyre.

I'd run it, doesn't look like there's many more miles on that tire anyway. Starting to square off pretty well.

Run it; it's fine. Don't need to do nothing.

Around here, in the winter I get 3 or 4 things like that every time I go out. The problem with doing nothing is that holes and cuts like that pick up bits of gravel and such like and those bits can cause a flat. I keep a tube of black polyurethane caulk, 3M 5200 is a popular brand, in a caulking gun. After every ride, after my tires are dry again, I fill these holes and cuts with caulk. In 24 hours or a little less, the stuff is cured and ready to go. When I'm done using it, I squeeze the gun enough to extrude half an inch of material to grab onto next time and then tape over it with masking tape. Next time, untape, pressurize the gun, and pull the partially cured plug out of the nozzle. Ready to use again. Don't get it on your hands, you'll have a heck of a time getting it off.

You have to look in the hole or cut and see if any carcass threads were cut. If they are, then the tire will bulge when pumped. If it bulges enough that the tube might possibly come through, you need to boot as well as fill the hole. Otherwise, you don't need to boot, just fill the hole. I don't use superglue, because I've found that old superglue acts like glass and can work its way through the belt and cause a flat. Looks good when you do it, but can have a bad result if there's much superglue in the hole or cut. Yeah, I know, sounds rather anal. But it keeps my tires going.

As long as I'm going over my tires anyway, I'll use the point of a knife to flick out any stones or bits of glass which are embedded but haven't caused a flat - yet. I dislike flats.

I see it now - I'd take a small screwdriver and check that there's not a small sharp rock/shard or glass or other object in there that might work it's way through the belt and cause a puncture. When you're happy that there's nothing in there, you should be good to go.

coasting 

how about using the liquid rubber in patch repair kits to fill the hole?

Thread should end here.

Or just pour some super glue in there. That will hold it together just fine and prevent it from tearing. I've done that several times, even with cuts through to the casing, with zero problems.

That's nothing -- looks like it came from a rock or glass shard.

As others have suggested, use a small blade to check for and remove remnants. I would not fill it. This is an extremely common situation.

coasting 

Just tried. No good. When it dried, it disappeared to nothing.

I get stuff like this in my tires all the time. Do make sure there isn't a piece of glass or sharp rock in there.

svtmike

Yup, I'd make sure there's nothing in it and then just run it. It's just the evidence that the puncture resistance layer did its job.

banerjek

BTW, if that hole were double the length, the advice would be the same -- use a blade or small screwdriver to fish out remaining glass/rock in the tire and not worry or do anything about it if the casing was OK.

hyhuu

I do this just about every week. The tires have so many, many of those holes and tears that I'm amazed that they aren't ruined yet. I wonder who are the people that rode their tires until the thread started to show?

Bikeforumuser0017

Thanks for the input guys. I'll probably boot it and fill it with caulking.

Guilty. Sometimes it seems like those darn cords appear out of nowhere :-0

jolly_ross

I get the picture.

It's not a wear indicator, it's just a normal puncture - I'd superglue it and ride on.

In fact, you could probably skip the superglue step.
