A small piece of tire is missing. What should I do?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Ok, before you tell me to change the tire. There is a small hole (about 1 cubic mm), but it was made by my trainer (either cheap tire or too much tension on trainer); So was no puncture to the tire, Is the tire still ridable?

A cubic millimeter is is about the size of a grain of sand. The tire is pretty much untouched, or you aren't very good with units.

A picture would help.

I wouldn't ride that tire. Risk vs Reward is not there. New tire - $35 or damage rim or worse - $$$$

I'd relegate it to a fulltime trainer tire at this point. Chunks tend to turn into blowouts in my experience.

Would putting some shoe goo in the hole work?

You can probably put a tire boot in that thing and use it but +1 to the "relegate to trainer duty" advice

It's fine. Fill it in with some superglue if it bugs you. Once you start riding a little, you'll find if you go off replacing your tires after every little thing, you'll be out a huge amount of money.

General rule of thumb for me is if the casing is undamaged, I'll keep riding it. If the casing is damaged, I deal with it on a case to case basis depending on the extent of the damage. If it's a small tear or hole, I'll boot the tire and keep riding for a while. If it's a large hole, then I replace.

No. If it were, I wouldn't be posting this thread. I also ran it up to 120psi. I think it's fine. I'll probably boot it like what Brian said.

Are you sure it's not the tire's wear indicator?

+1

1 cubic mm would be about right for this. Is is a perfectly circular hole?

I've always ridden my rear tires until the cords start showing, which means virtually all the tread rubber is gone, not just a little chunk. A little random chunk missing or a cut doesn't mean much IMO if the cords are intact and not compromised. Cut/damaged cords would normally be evidenced by bulging. The fact that this happened on a trainer is a bit curious. It suggests perhaps that the tread rubber and/or it's bond to the cords has been been compromised by the stresses involved. Having big chunks or strips of tread rubber coming off while riding would be less than ideal.

For typical cuts or divots in the tread, I just leave them be.

This.

Even if it weren't, who would be concerned over a cubic mm? Hell, you'd have to throw away your tires every time you rode over glass or gravel.

I would boot it and ride it too. If it were a front I'd move it to the rear.

I kept some bad tires alive with super glue for waaay too long, but they never failed on me.

Shoe goo or super glue will do the job if you dont want to get new tires.

Am I hearing that a bunch of people would actually repair a tire missing a 1mm chunk?

Whatever the case, I'm happy to take any frames, forks, or components that you've scraped and need to chuck.

Not seeing a picture, but a big +1 to a square mm being not worth a moments thought. Keep calm and carry on.

Pull out a ruler/scale and re-affirm your idea of "1 mm". It's REALLY really small.

I'm estimating 1 CUBIC mm. It's Certainly more than 1mm wide but not even 1mm deep.

OK. It might be 2 or 3 cubic mm, but no more. Look at the giant picture. You have a dime to compare it with.

My front tyre has a hole about 2mm wide and deep, all the way through the threads. I can see the inner tube. I keep meaning to replace the tyre but when I ride it it is perfectly ok. When I get a flat, I'll just deal with it then.
