What about wetsuit repair glue - does that have better adhesive qualities than super glue? If the cut is not too deep and tire is not very old then I’d try something like that, otherwise trash it.
LC … fill the gash with the tire inflated if it’s big. Doesn’t matter if it doesn’t stretch: all you want to do is clog the hole so no crap makes it way to the casing and end up puncturing the tube. From what you’re saying, it’s just a little cut not worth worrying about.

Martin,
I know you are experienced but be careful. If it hardens up and is in the cut the constant rolling could cause the cut to expand. I would move the tire to the back wheel just in case it goes. Or better yet, make it your trainer tire. BTW, Super Glue in a cut finger works great. No band aids to fall of in master’s practice.

I meant: “Don’t try to keep the cut closed with the glue: it won’t hold. Just inflate the tire and dab some glue in there”.
You have to read my posts and imagine I’m talking. Gestures, accent, and all …

seems like squirting that gunk in in your tube
What are you talking about?

Oh good … I thought the Krazy Glue discussion had gone for the worst.
I’ll go get dinner. Carry on …

If I remember correctly, you want to use crazy glue brand super glue for fixing flappers and cuts on people because it’s not as toxic as regular super glue.

“Superglue” or any of its ilk, are referred to as cyanocrylate, or CA. The properties of CA make it terrible for something that will suffer repeated stresses in different directions. It is very brittle, it won’t move with your tire, and thin CA will run all over the place and get into everything before it cures. Additionally, it gets extremely hot in decent quantities and might melt onto your inner tube if used as a road patch. Thick, gap filling versions of CA are available, but they won’t be any better on the road, in fact, a thin repair would probably stand up better than thick one.
As stated, it is extremely brittle. I wouldn’t put much faith in it.
I have recently seen a company advertising flexible CA but do not know anyone who has used it.
If you are set on trying to repair a gash, a contact adhesive might be a better bet. Apply it to both surfaces, wait till they dry, and press them together. It makes a very strong bond, and will be flexible enough to match your tire’s movement.
Acetone is a good solvent for all CA derivants.
I’m not saying it won’t work, but I definitely think its not near the best choice.
I used to have a bottle of something that was made just for the purpose of fixing small cuts in tire tread. I think the name of it was “Flat Fix”. It looks a lot like super glue, but apparently was designed to deal with the flex issue.
