After only a few rides of being tubeless, last night I suffered two punctures on my rear tyre (scwalbe Nobby Nic).
Both snake bite type I reckon.
The stans sealant wasn’t very quick to seal but did so eventually on both occasions but now I’m concerned my tyre is vulnerable to leaking again if it is battered around.
One of the pops appears to be near the shoulder of a nobble and I wonder if the action of this squirming around might just reopen the hole and it start leaking again.
What the best course of action now. Safest is presumably a new tyre but that sort of defeats the point. Put a tube in it?
Should I stick a patch on the inside of the tyre, like the old fashioned vulcanising type?

This follows on nicely to the book marked Huck Norris ghetto thread!
Punctured rear tyre last week with what looked like a small nail hole. New sealant put in as hadn’t changed it for at least 18 months. Still alive. If it stays up jobs a goodun
I tend to stick a traditional tube patch on the inside if it's a big enough cut, otherwise just trust the sealant to deal with it. Only found it to be problematic if you inadvertently find the sealant has dried up and the original cut may then reopen.
Yes, if it sealed during the ride at normal pressure you can trust it.
Check your sealant levels if you haven't already.
A tube won't help, procore or huck norris will.
I had a nasty one right in the middle of the tread on a Hans Dampf last autumn, I was quite impressed that Stans managed to seal it. Held up well for a few months, but at BPW last week it let go and would'nt reseal. Hopefully a puncture repair patch on the inside will fix it.
I find that beyond traditional small bore pentration type punctures, if spooge does seal them, they tend to be a bit niggly.
Easier to stuff an anchovy in to be sure.
I work on the basis that if it's big enough to take an anchovy, it gets an anchovy.
I'll always stick a tube patch on punctures that I'm worried about (once I get home). Hardly a big deal, and they're bomber... Why go riding with that niggle in the back of your mind?
If it was me I'd opt for a new tyre given you're going to Morzine, if only for peace of mind. In the meantime, I'd repair the old tyre and take that as a spare to Morzine.
Hang on.....snakebite punctures on tubeless? So you think you are pinching the tyre itself against the rim, and that is causing the whole in the tyre?
I think so, one was at “high speed”down a rocky track, the next a slow slam against a water bar.
It's perfectly possible to snakebite a tubeless tyre. I've done it loads of times, including breaking rims at the same time.

Okay, I'll take your word for it. I'm guessing I don't go to pressures low enough for this to be an issue - I only ever seem to get thorn punctures and rock cuts with tubeless. Seems like quite considerable deformation for the tyre to pinch against the rim hard enough to cause a hole, but I can see how it might happen. Maybe use slightly higher pressures?
Okay, I’ll take your word for it.
Um, ok. I'm not really trying to convince you.
Using higher pressures is certainly one solution, but you face a compromise with tyre traction and tyre feel. Not everyone is happy to accept that.
Um, ok. I’m not really trying to convince you.
Sure, I realise that. Meant more in the sense of, I've not experienced it myself, but I can see how it could happen.
This is exactly the sort of ham fisted smashery that causes a snakebite in a tyre. Bloody lucky to get away with it.
I've had quite a bit of success with superglue.
As long as the 'nick' in the tyre is clean, then you can glue up the rubber from the outside.
If it seals without a plug I will leave it. If I have to plug it on the trail then once back home will mend it with a mushroom plug

Depending on what you are doing and how long you are in Morzine I'd just buy some Super Gravity / Double Down style tyres and fit them. Being in the mountains can mean a long walk with a totally failed tyre.
Previous punctures aside, there's no way I'd go to morzine with a nobby nic on the rear.
