Brand new tubeless tyre with a sidewall cut
Schwalbe Pro 1, got a sidewall cut in about 200kms. Loath the idea of tossing it. Any possibility of salvaging it?
I patched it from the inside, and the patch developed a hole and blew out as soon as the tyre reached 100psi. I ride at 90, but wonder if this is safe at all.

Doesn't matter if it's at 200 or 2000, toss it.

Bad luck. I wouldn't ride it. Just sometimes happens that a tire is ruined right away. I had a Pro 4 Endurance tire get a big hole after 500 miles, and chucked it. The other tire never got a flat though, and it is starting to show through.

You're not saying HOW you patched it.
If you only stuck a regular tube patch on there, failure was to be expected.
I fix sidewall tears by patching with liquisole and nylon fabric, and those patches tend to last the life of the tire.

I used a tube patch. What is the nylon fabric that you use?

Tires are more than rubber. They have a reinforcing layer of threads. You might have seen tires listed as having this-or-that TPI - threads-per-inch. For any chance of a lasting repair your patch needs to have a similar structure.
I've used patches cut from an old jacket liner. I work liquisole into the patch until saturation before applying over the cut. For a road tire I'd patch both sides. You might want to stitch the cut closed first. And clean/roughen the surface first. I've used abt 15 mm overlap.

Deepak...I know you don't want to be wasteful, but just toss it. Not worth a wreck. You have the $.

You might try reaching out to Schwalbe, tell them you have low miles and how bummed you are given they aren't cheap. I had a small bubble develop on the shoulder of a Pro One and they replaced it. It's all done online, they'll have you take a pic and fill out a form. They may replace it in the name of good customer service, worth a try. Whatever you do, don't ride it anymore.

You didn't buy world class tires so that you could ride them cut up and patched. Tires are just that way, sometimes you get a lot of miles out of them, sometimes you don't. It is all averaged out in the end. Don't think of this one as unusual. It is just part of the overall average. Scrape your shoe and move on.

If you must use that tire I would boot it and tube it and put it on the back. Mount the booboo opposite the valve and chances are you will never notice it.

OK guys. Thanks. I think I'll boot it, put in a tube and relegate it for trainer use. Considering that I have not used my trainer more than thrice in 10 years, it should last for ever.

You could try using a radial tire sidewall repair kit.

I've patched cuts in tubeless tires before, if its less than 10mm in length it's probably worth trying to save.

Just a cut in the rubber or did it cut into the threads of the casing? If only in the rubber, I wouldn't worry other than to expect it to fail sooner than later.
If the threads of the casing are cut, then ride it if you want. Just be careful. Don't be racing down any mountain roads with switchbacks. If you only get one more ride on it, that's less wear and tear on the new tire. If you get a dozen more rides out of it even less wear for the replacement tire. However I do tend to replace cuts that go into the casing if inflating the tire to normal pressure makes them pooch out.
I've never had an accident or wreck from a flat. I'm sure others may have. None I've had were dangerous other than just a little squirrely for the wheel with the flat tire.

The only way I would ride a tubeless tire that was cut and patched would be temporarily, with a tube, until I get a new tire on the rim. Just not worth the risk.

Your question would have stood up on it's own. I never see the point of adding the confusion of old comments to to a new question. Even if a 1000 others have asked the same question. Just think how long a thread and confusing a thread would be if everyone wanting opinions on a new bike posted in the same thread. Nobody would know whos is answering whos questions.
I was answering the OP's question!

I didn't notice it was a zombie thread. Shame on me!

Now you've made me and everyone else sad since you don't think we could answer the question. <grin>
You still could have done a new thread, referenced dabac 's reply by copying the reply number of that post and pasting it into your new message. https://www.bikeforums.net/19726684-post6.html
But still what you did here does work. But if this had been a long and contentious thread with many members still active, you might just be dredging up old arguments and posturing. And your question could be entirely missed all together.

Thankfully, @deepakvrao is still with us. He must have done the sensible thing with that tire.
