tubeless tyre repair fail

I havre the same tyres and had a large hole caused by a sharp stone in the Alps last year. Fixed it with a largeish patch inside and also a bit of flexible superglue from the outside and it's been fine since.

I’ve tried a few sealents now. Found Effetto Mariposa Caffelatex to be really good. 

Can’t see which sealant you used, maybe I missed it. I didn’t even try the Mavic one with my Ksyriums and Yksions, because I’ve found that Stans Race Sealant is stunningly good. Haven’t had a flat since I started using it about 3 years and 20k miles ago. I did have trouble occasionally with others.

I have found Orange Sealant works the best for larger tears.  Just remember to swish the wheel around to get sealant on all parts of the wheel ie the sidewalls.

Before I gave up completely on tubeless on a road bike, I had numerous patches on the inside of the tyres.  The downside is that the liquid sealant works away at the patch and they  come off after a while.  Best plan was to clean all the sealant out, clean the hole up and put a blob of McNett Seamgrip on it and leave that to dry.  Need the hole to be at the lowest point, somewhere warm, for about 12 hours.

Best thing though - throw the bloody things away, put some Michelin Pro4 Service Course on it and stop pretending that the King's new clothes are awesome - they're not - they're full of holes, as you well know....IMHO, of course.

Must've been the day for it: I pinch-flatted a Mavic Yksion pro on Thursday too. Ended up with 2 snakebite ~6mm long cuts, one a few mm from the bead and another ~15mm higher up. I had to put a tube in as the sealant did jack.

I've since put a regular tube patch in place that covers both cuts and that seems to be holding just fine. I used a clean but rough cloth to clean any residual sealant from an area bigger than than the patch before fixing. I've since read that some people put some duct tape over the top of any patch too.

FWIW, this was my first tubeless flat.

Just remembered an alternative tubeless repair is to squeeze some rubber glue (e.g. wetsuit repair glue - https://www.amazon.co.uk/McNett-Black-Witch-Neoprene-Adhesive/dp/B000SCJQYQ) into the hole and leave for 24 hours or so. I've also heard of people using superglue to repair tyres, though that sets hard which can cause problems.

There is always the DynaPlug system, I've not used any, but will eventually get some, you know just in case, better than fitting a tube for the larger holes, maybe.

And those anodised pill holders, pricey, but they are so cool.

If the hole is less than 5mm width then it should seal with just the sealant, but if it's bigger it can be problematic. I've used those "sticky cores" or anchovies and had the same issue with the pressure pushing it out on a larger hole and I've also had success with using one on a smaller hole (though bigger than 5mm), so it might be that your puncture is too big for the anchovy.

You could try a patch on the inside of the tyre instead, though I didn't have much luck when I tried that with a Schwalbe Pro-One - I ended up binning the tyre as I didn't have the patience to keep mucking around with it.

I have used a patch before, just make sure you properly clean the area and you can save the tyre. As to noodles, it depends on the size of the hole, I always carry two sizes one quite thin, one thick one. If it is blowing out possibly it’s a big hole and needs a bigger noodle or a second one. Top tip have them pre loaded in the tool, that way it’s a mega quick process if you need it on a ride. 

I had a similar issue, but now I never go past 80 psi on my 25s, (im 90kg) these are on my hunt wide carbons and 70psi on my 28s. Rides great and no issues. Stick with them, they can be a little frustrating at first while you learn to live with them. After that though they are great. 

With car and truck tyres I drill out puncture and plug. Works easy. Easier on truck tyres due to higher pressure and lots more volume. Mushroom shaped plugs are even better but the tyre has to come off to push mushroom trunk through hole then glue then mushroom head to the inside of the tyre, pressure strengthens seal of such.

Can you remove your tyre, collect the remaining sealant, glue a tube patch to the inside of your tyre and reassemble?
