Tubeless puncture!
Hello there last year I had a pr of new wheels built with tubeless 700x30 shwalbe pro one tubeless tyres fitted which proved to be great until fully loaded with 80km to go the front tyre would not seal anyway I made it to a local bike who did not do tubeless so I had to have a tube fitted which I carried on with until the end of the summer . Anyway now having stripped the tyre off and cleaned it I would like to go back to tubeless however I still have the small around 3mm hole in the front tyre , these tyres are only one year old and around 900km so I do not really want to simple buy a new tyre , but I need to seal the hole could I simple as the tyre is off the rim apply a puncture repair patch to the inside of the tyre , or because the tyre has been tubed for a no of miles should I buy a new tyre ?. Any ideas most welcome as I am new to tubeless!.

I'm really impressed with Schwalbe Pro Ones. 🤷
I went for the Hutchinson tubeless patch kit, MTB as my tyres are plus, there are road versions. Thick, feather edge patches and what seems to be a tube of flexible superglue. For more of a permanent repair than anchovies. I have what has seemed to be a permanent anchovie repair, and thought about using the kit, but didn't want to open the glue as once opened, it WILL be dried up when I really needed it.
There are other manufactures kits out there, but I'd heard good things about Hutchinson's on here by secret-squirrel and on the web.
I've found that the Schwalbe Pro Ones are very delicate compared to other tubeless tyres, so although 3mm should be fine with sealant, you may have trouble.
One idea is to use wetsuit rubber glue to fix the hole (e.g. https://www.ebay.co.uk/itm/322419863015?epid=1540671415) and once that's set you should be good to fit it again.
Not had good experience with Schwalbe sealing. I gave up using them and switched to Conti 5000s.The Giant own brand tyres have been good too, and I know I've punctures them because of occasional larger top ups after a ride.
Schwalbe construction just seems different. The older Conti 5000TL apparently have an inbuilt self-sealing layer and they certainly inflated onto the rim ok without sealant. I've added sealant. I've got two seasons out of a front tyre and a season out of a rear - about 4000-5000 miles a year. Schwalbe I've had one last 5000 miles and a rear having to be replaced a couple of times in a season. A friend riding on Schwalbe had similar experiences of punctures failing to seal.
I think a 3mm cut is too optimistic to seal on a Schwalbe (it may also depend where it is - sidewall damage seems especially difficult to seal due to flexing). There probably will be carcass damage. You can try patching but remember that an inner tube patch is held in place by the pressure pushing on the inner tube against the tyre, any patch on a tubeless is going to be flexed without a layer of rubber holding it in place so you'll need a specialist repair kit.
You don't want to mess around with bacons strips on a road tyre, you just need one of these :

Like an inner tube patch except goes on the inside of a tubeless tyre. 100% reliable. I have 1 tyre with 3 of these in still going strong.
I have also had good experience with tubeless patches, but I have only used them on damage in the tread area. I get nervous about side wall repairs (probably just superstitious nonsense).
the "anchovies" are good for get you home repairs but I have found they can get plucked out over time - even if you glue them in. Whereas with the patches the pressure in the tyre helps hold them in place.
Thanks can those patches also be used on road tyres I noted they said MTB ..yes the damage is in the tread area otherwise I would probably dump the tyre .
As it's on the tread area I would just use the tubeless patch Mr Squirrel suggested, it will work fine and be held in place by air pressure.
I thought the idea of tubeless is once they are on, they stay on rather than having to remove them to fit a patch.
Also if you get a hole on the road, you want something that will fix it then and there hence the external kits
Thanks secret squirrel are yours on road tyres ? As mine are schwalbe pro ones 700x30 which don't seem to be getting much love on here .
The 3zer is a schwable G-One speed, then I have 1 in a v1 Pro One and have just fixed a Pro One evo with a small tear where the rim meets the bead. Holding after 200miles.
@Hirsute you generally can get away with just breaking the bead seal, peeling back the tyre and wiping the hole spot clean rather than a full removal. Only a weird "j" shaped tear in my G-One a required full removal and that was mostly for accuracy of placement.
Thanks I will get some does this mean there's no point in using the plugs ?..and I have been trying to find the road versions but can only find the mtb ones does it matter for my road tyres ?
MTB ones are fine.
To get you home use worms/plugs or just whack in a tube. Personally I found the tick tick tick of the stubby end of a worm poking out of a road tyre really upsetting to my ocd.
For 3 mm, the sealant should fill the hole, so your sealant was old and needed topping up, or you need better sealant
