Shards of glass in the tyre !

Hi !
Just curioius, I was checking my 23 c tyres and saw small shards of glass , almost a 1mm, they did not go through.
I removed them, just wished to know how do you cover or patch these small nicks in the tyre ?

If small enough you really don't need to fix them. I fill some holes with super glue.

Actually , since the tyre pressure is 100 psi gets me thinking , maybe the nicks increase in size, thus the caution.
You mean the liquid glue that dries in a couple of seconds !

I tried Super Glue after reading that tip somewhere. The problem is the glue hardens into the shape of the piece of glass that formed the hole. The shard of glue will eventually cut through your tube and cause a flat.

I've been using super glue in mine for at least 15 years and have never had any such problem.

Awesome idea
Actually me thinks, if we put the glue in the deflated position, then the gap won' t be so prominent as inflated, and we would have a smooth dry, so AL1943's concern would be sorted out.

You obviously haven't been riding long in any US metropolitan area. Tires get nicked all the time, and any tire with a decent amount of mileage will be full of nicks and cuts. Obviously, if you see a small shard embedded in the tire you should pick it out, but you need to get some perspective and accppt that this happens or you'll go nut obsessing over your tires.

As far as what to do, that depends on the depth and size of the nick. If it's into the cord, super glue or whatever won't help because the structure is damaged and will begin to tear apart causing a local bulge, then eventually a failure.

If the cords are undamaged there's no need to worry about the small nicks. If the nicks are bigger, you might try gluing them closed, or gluing in a piece of an old tube as a filler, but I've never bothered unless they were very big with an obvious section of tread missing.

Years ago they used to sell "tread stopping" compound as a filler for these nicks and cuts, I haven't seen it of late. They probably stopped making it because folks figured out that it didn't make any difference anyway.

Tires that last 15 years don't see the miles my tires do. The superglue eventually wore a hole in my inner tube, which in my case was a couple of months. YMMV.

Intentionally inserting small hard bits of glue or anything else into your tires makes no sense to me. Why do you do it?

Try using 'ShoeGoo' Works fine for me, it's carried in most sporting/sthletic shoe stores.

Who said anything about 15 year old tires?
The only reason I ever put glue in tire cuts is to keep small pieces of rocks or glass out of the holes.
Rear tires on my bikes last about 2000 to 3000 miles or about a year.

I didn't know I had a concern.
I've tried filling the hole with super glue with the tire inflated and then partially deflating the tire to put the glue under compression. But I could not see any advantage to doing this.

So to prevent the very slight possibility of a small hard object from entering a tiny preexisting hole in your tire, you intentionally put a small hard object in the hole? It makes even less sense to me now, but thanks for answering my question.

Gee, the trivialities folks can get so worked up over. You may disagree, but what does it matter?

I also disagree, and ignore nicks and cuts because they aren't worth the bother, but that doesn't make what Al1943 wrong. To each his own.

And I agree. I think it's trivial. I thought that was obvious from my post #2, but the OP asked. And it's too rainy here today to ride.

I'm hardly worked up about it. I just wanted to share my experience and my opinion. I'm not sure what the purpose of these forums are if not for us to learn from each other.

An attempt to repair a tire that results in puncturing the inner tube may be trivial to you but it's not trivial to me.

+1.

I have been using black Shoe Goo forever on nicks and cuts. Dig out the glass/shard first, plug with Shoe Goo, then scrape flat. Done.

Much hilarity in this thread. I reckon q's cut was pretty deep if the c/a glue cut his tube. Most cuts that don't go past threads should be no problem if patched with superglue, however. It would seem a more flexible glue would be preferable, but whatever.

I don't bother myself. I just run cheap tires and replace often.

Luckily I no longer work right next to the glass recycling plant. That was a rough year and a half.

<shrugs shoulders> I've never filled any split or cuts from such things and I've never had any issue from them picking up further junk.

Atlantis, the rubber of the tread isn't what holds the tire together in any event. So a nick or small cut won't get bigger with time anyway. It's the cord belts within the rubber of the tire that hold it together. Without these belts the pressure we fill the tires with would make them swell up like overfilling an inner tube not in a tire.

If you have a cut in your tire and it DOES get bigger than it cut in deep enough to cut the cords and the extra pressure on those beside the cut is allowing them to snap. In that case a tire boot or replacement is in order, not glueing the tread back together.

Come on Lester, a hard bit in your tire will eventually go through the threads if you ride over it enough times and I think you know it. That's why we remove small pieces of glass and stone from our tires. The holes I filled with superglue were not deep, they were superficial and I put the glue in the cuts solely for aesthetic reasons.

It's a bad idea.
