Shard removal

brianomc · 21-01-2015 8:20pm #1

After examing the tire and removing all the little shards of glass that stuck in it over the last few weeks I am now left with a tire with a fair few cracks and one quite serious looking cut. Has anyone used any sealant they can recommend or is there a good reason people don't do this? Google threw up nothing for me.

The tires aren't that old so I don't want to throw them out unless I have to. Running on GP4000 23's usually pumped to 110psi but I may have let this slip a bit lately.

Depending how serious the cut is. Pictures?

Only about 7mm in length but peels up quite easily. In saying that I took the shard out of that one a few weeks ago and nothing has found its way back in. But the thoughts of super gluing it crossed my mind at fhe time.
Sorry if the image is massive. Uploaded it from my phone, will try edit it if it is

I just use super glue. For a large'ish "hole" I might use a small piece of rubber from a tube or more recently, from those rubber bits you get with light to protect your handle bars etc. Along with the super glue.

For the hole in your pic, just super glue.

I am running on Conti 4 Seasons and I do the whole shard removal thing every week if I can.

It never ceases to amaze me how many punctures I have avoided, even if the odd shard does get through. Probably 10+ a week.

Superglue cracks as it gets harder/brittle. I ran a commuter on 26's with a larger sized shard-piercing for a fair few Km's, and had used some rubberized (vulicanized?) glue in them. I don't know how much good it did though.

Thanks all. I will try some of that loctite 480 in the link for the bigger crack and just ignore the rest for now.

E6000 Craft Adhesive was recommended to me before. Works well. Available from EBay, Amazon, etc.

For the reasons mentioned above, *don't* use Superglue

I usually use a bit of the glue from a puncture repair kit. It doesn't harden and crack like superglue.
Its not perfect either but it seem to work

I use black witch neoprene glue. Haven't had any issues so far.

Was also going to suggest black witch.

Tangentially - I assume when filling these holes with glue, you do it with the tyre fully inflated? I can't imagine any glue holding after pumping a tyre up to 120psi?

Had a cut a little worse than that last autumn , I put a patch on the inside and have used it a lot on the turbo and as a winter tyre . No issues since .

Wonder would this be good on minor cuts

I don't think so. With the tyre inflated, the cut often opens while the casing prevents it splitting further. If you glue it at that point it will stay open and the glue won't take. OTOH, if you glue the cut with the tyre deflated and allow it to cure properly, the cut should hold together when inflated.

I've been using Tec7 for a few years with good results.
