[Closed] Pinchflat on tubeless tyre, fixable?

I've fixed one like that a couple of months ago. Just used a patch on the inside of the tyre. Was fairly close to the bead but it seems to have held so far.

Yeah, done the same, and fixed successfully with a bit of an automotive anchovy.

I've sealed similar bead holes mid-ride with a Dynaplug without removing the tyre.

That's good to hear...

Any recommendations for tyre patches? I've seen the mushroom type, but concerned if I used one of them or anchovy in it might not seat so well from the outside (also heard the anchovies are not long term solutions). Struggling to find patches that aren't inner tube patches.

use a mushroom from the inside,trim it close ont he outside after its cured. I might be tempted to put a normal patch on the outside as its right on the bead.

Anchovies are normally fine long term but your tyre's off now so use a mushroom, which is better anyway IMO. Right on the bead an anchovy also has the disadvantage that the distortion it causes might affect seating, and mushroom better for that. If even the mushroom stops it seating nicely a straight patch might be better, but I'd expect a mushroom to work.

I buy the smallest size automotive mushroom patches. 3mm IIRC. I find them excellent.

Also used a Dynaplug on one of these with success after pinching the rear tyre on my E-MTB, its still in there almost a year later, almost forgotten about it until this thread reminded me TBH.

Anchovies in the tyre bead are a good permenant solution. I think they're more likely to get ripped out if they're in the centre of the tread and in contact with the ground. They'll happily spend the rest of the tyres life sat against the bead with nothing to interfer with it.

I've had 3 dynaplug anchovies in the bead from pinch flats since May.

Fixed one like that with anchovies the other week.

Holding up fine.

If it's a recurring problem, look at a Rimpact insert for the rear (they are nice in the front too).

I'd suggest this repair kit BTW...

I would clean it up and put a big blob of stormsure glue on the inside and leave it for a day or two.

I find these types of patches are the best as they seem to stick much better and can be cut to fit... + Fill the hole and surrounding area from the outside with something like shoogoo or whatever you have once the patch inside has cured properly.

For that repair, you don't want an anchovy or mushroom, you just want a standard innertube patch (big one from a kit, or get a sheet of patch material and cut to size). Mushrooms are for decent sized holes/tears, anchovies are for trailside repairs, basically. I mean, you could get any of the three to work but the best option is definitely just a patch.

Any sort of repair from the inside is naturally strong, because the air pressure is holding it in place rather than trying to blow it off.

Thanks everyone for the replies.

I think a patch on the inside makes the most sense in my head. I've ordered some patches and some vulcanizing cement, will post here if it works.

It lasted fine with an anchovy and a patch.

I fixed a problem like that with a patch on the inside as suggested and a mushroom plug in the other part of the pinch flat..

Your biggest problem though is Maxxis tyres.. they're dreadful and do that a lot....
