superglueing tyres

sloxam

after checking my tyres today i found lots of nicks/cuts. they range from 1mm to 3mm in size. i put superglue in them as i have read that its good for repairs. how long does the repair normally last? is just an emergency thing until you get a new tyre? also is 3mm too big a cut to repair?

Not very long - in fact the first ride in the wet - superglue is hydrophic and the best thing for weakening the bond is water

Not sure that was quite the word you meant to use

In any case, whilst superglue is hygroscopic - it absorbs water - it only does this very slowly, hence you can successfully repair teacups with it.

I agree. I use a lot of so-called super glue in different grades and the only way to un-glue anything is with acetone (nail varnish remover is a poor alternative). The only problem with it is that the stuff sold in DIY shops tends to be very brittle. There are more flexible grades. Try a decent model shop, though they are very thin on the ground these days.

Hi there.

I've successfully used glue for lower pressure tyres (comuting bikes at 70psi etc), but for higher pressure stuff the glue never seemed to hold.

@Monty - superglues were originally designed to be used as field sutures - they set in moist anaerobic enviroments. As noted there are different grades for different applications, a more flexible one may work better for a tyre application.

Hi again.

On the other hand, even pro mechanics seem to be handy with the super glue:

I explained there why I don't glue cut tyres any more :shock: !

I think you need to take a judgement on how deep the cut is. Nicks may fix ok, deeper cuts and you might me in trouble like Colin was.

Whoever told you to glue a sidewall split needs certifying! If you've got a nick in the tread then try superglue but if the sidewall is split it's new tyre time.

I think that was probably me, myself, I :oops: !

Yeah, I reckon a small cut in the rubber would be okay to fix as long as it doesn't go all the way through the tyre. And I'd certainly keep a close eye on the repair.

Split side wall, replace, If you can see the tube, also replace, but for little nicks after removing flints glue is ok.
This week I punctured removing splins so guess I learned its better to let the tye down and remove before getting flints out
