Repairing a tyre tread - Schwalbe Marathon
Re: Repairing a tyre tread - Schwalbe Marathon
This blue mark appeared about a 1000 mile ago, I may even get another 1000 out of it, won't replace it until there is 3 or more. I used to worry about them but now they don't bother me. (as long as it is not a front tyre!)
Re: Repairing a tyre tread - Schwalbe Marathon
Thanks, but superglue dissolves in water, so that solution is a chocolate fireguard I’m afraid. If you read the instructions that come with superglue it tells you to dissolve it with water if you accidentally stick your fingers togetherPH wrote: ↑14 Nov 2022, 8:18pm I'd stick it down with superglue, make a note of where it was (maybe mark the sidewall), use it as a rear tyre, check it periodically for the first hundred miles, or till I forgot about it.
I don't think it's structural, I've run several tyres with with that sort of layer below the tread down to that layer, most frequently when commuting on Vittoria Randonneurs, never any sign that the tyre was compromised in any way other than not having any tread!
I’ve stuck it back down using the patch adhesive from the puncture repair kit I carry on the bike. Why go spending time and money buying rubber repair glue when you already have some? If it stays stuck down when I’ve scrubbed it with soapy water and a nail brush after it cures fully, I’ll go for a ride on it and see what happens!

Re: Repairing a tyre tread - Schwalbe Marathon
Superglue Gel is designed to be more water resistant than standard and also more flexible so better suited to an application like this, but then one is getting into the realm of an unnecessary specialist product.PH wrote: ↑15 Nov 2022, 1:45amI really wish I hadn't botheredhttps://craftsbliss.com/is-super-glue-w ... 27s%20holdNearly every super glue on the market is 100% waterproof once it has thoroughly dried onto the surface of a material.

Re: Repairing a tyre tread - Schwalbe Marathon
Does vulcanising solution work on tyre tread? I have plugged small round holes in tyre tread with shards cut from discarded tyres and stuck in with vulcanisisng solution, but I have not been sure whether the shards stayed in because of that, or because they have been wedged in. I let everything set, then trim off excess.
But I haven't tried it with the extended sort of hole shown in the pic.

Thanks very much for responding with the best of intents, however, from the same link that you provided above:PH wrote: ↑15 Nov 2022, 1:45amI really wish I hadn't botheredhttps://craftsbliss.com/is-super-glue-w ... 27s%20holdNearly every super glue on the market is 100% waterproof once it has thoroughly dried onto the surface of a material.

"Will Super Glue Hold Under Water?
If you have an item with super glue on it, and it is underwater for a short while, there shouldn't be too much of a problem. But, if held underwater for long enough, the adhesive's bond may lose performance a bit."
You have to read all of a report to get the full picture. Superglue loses it's grip in high water environments which is exactly what a tyre is in when it is raining. The constant flow of water will degrade it's adhesion.
Re: Repairing a tyre tread - Schwalbe Marathon
Try the vulcanising solution (from a puncture repair kit) then. Cover both surfaces with a thin layer, wait a minute for it to become dry to the touch, then press the surfaces together and keep gentle pressure on it for a few minutes. Store it in a place that is not cold for a day or so before use. It should work.saudidave wrote: ↑15 Nov 2022, 8:08amThanks very much for responding with the best of intents, however, from the same link that you provided above:PH wrote: ↑15 Nov 2022, 1:45amI really wish I hadn't botheredhttps://craftsbliss.com/is-super-glue-w ... 27s%20holdNearly every super glue on the market is 100% waterproof once it has thoroughly dried onto the surface of a material.

Re: Repairing a tyre tread - Schwalbe Marathon
There are many varieties of superglue. Some are indeed very brittle and won't last past a few revolutions on a tyre-mend. Others remain quite plastic and work on small rubber-sticking jobs as long as what's glued is cleaned of grease, dust and other dirt. Isopropyl alcohol is a good prepping cleaner for such work (and many other such cleaning tasks, e.g. for disc brake discs and pads). It can be bought in bulk for not that much.PH wrote: ↑14 Nov 2022, 9:00pmWorks absolutely fine for me and judging from the number of google hits, works fine for many others as well. The OP is only trying to stick a little divot down, there's no need to overcomplicate it.
If the mend is exposed to actual contact with the road, a rubber-based goo is better than any superglue I've ever come across. Superglue is a glue, not a patcher.

Re: Repairing a tyre tread - Schwalbe Marathon
I completely agree - a charmless and ungrateful response. I had considered providing a reply to the OP because there's an industrial product available extremely cheaply on eBay which provides a bond which is flexible but stronger than the tyre rubber itself - if you tried to pull two bonded pieces apart, the rubber would tear before the bond. However, I've had previous experience of the OP contradicting my real-world experience of a product I use every day, based on what he'd read on the internet, so I decided not to bother.
Re: Repairing a tyre tread - Schwalbe Marathon
So, I decided, as is my right to do so that an alternative opinion that I sourced on the internet had more credibility than yours and that has annoyed you so much that you have decided to post a personal attack on me on a public forum?

Re: Repairing a tyre tread - Schwalbe Marathon
OP Here
I repaired the flap of tread using the adhesive from a puncture repair kit. I cleaned the damage first, applied the adhesive to both surfaces, waited 30 seconds and then pressed it down firmly in to place. After leaving it for 24 hours I gave it a good going over with a scrubbing brush and hot soapy water which it didn't seem to bother about. I followed that up with a 40 mile ride today in rain, mud etc then had a good pick at the repaired flap, which stubbornly refuses to lift up.
I think its fair to say its a permanent repair and it cost nothing too.
