So the sharp South Downs flint finally got me this week and made a hole in my front tyre which wouldn't seal, not a problem I installed a plug (first time, worked as intended) and finished my ride with no further issues or loss of air from the tyre.
My question is what do I do now? Is it fine to just leave it as is, I don't think I lost much sealant, or should I remove the tyre and attempt some sort of more permanent repair, if so what with? Or smear a dollop of vulcanising solution from a traditional puncture repair kit over the plug front and back.
I'm riding the Frontier 300 next weekend so looking to eliminate any obvious weak points from my set up as it seems rather cavalier to just hope for the best.
Thanks.
Remove the tyre, save as much sealant as you can and fit a mushroom plug
Link for reference, you can buy multi packs for around £10
Done this to a few tyres now, zero issues
Sorry, double post, see below
As above, but you don’t need to take the tyre off, just the bit of one side of the tyre nearest the hole, enough so you can look inside (or lever side of tyre up etc) so you can clean the area around the hole, apply solution in and get the mushroom in,
Thanks chaps, ordered a couple, just hope they arrive on time.
Depending on the location and size I just leave it. If I'm not confident I'll remove and add a mushroom. Sometimes I just forget about it.
I would leave it with the plug left in, too.
"I just leave them in. Been fine."

I have a hole in my nearly new/barely worn Aggressor DD that I have to replug every few months with new worms as they dry out and start leaking. The big gaping hole makes it easy to add more latex, which is "nice".
Probably need some of those mushrooms.
I've had plugs last for ages, and I had once that ejected at high velocity and a loud noise...if you're carrying more plugs anyway I wouldn't bother taking the tyre off unless you've another reason for doing it.
If they keep on ejecting it’s worth putting one in with some vulcanising solution.
If they’re Dynaplug then they’re good.
Otherwise just leave them in.
Leave the worms in if they are doing the job. Otherwise put one or more in using vulcanising solution.
Also - if you carry a preloaded fondue fork thingy with worms already in - carry it with two small worms already installed. I find that punctures which would only require a single worm will nearly seal with sealant anyway and it is preferable to not having enough girth and watching your tyre potentially unseat as it goes down.
Unseated tyre = tube as it is impossible to reseat a tyre using trail tools IME.
Leave as is and just check how much fluid is in there, add more if at all concerned.
Just leave it in, the latex will gunk around the inside of the plug in a blob after a while making its's own mushroom anyway
I think mostly they stay in fine - I had one I used for a few rides fine - although the tubeless kit I had used glue as well as just the pressure of jamming it in.
I have bought some mushroom patches from eBay to more permanently fix said tyre now - although I’ve decided it’s too flimsy for my riding and going to see if I can sell it for anything at all on ebay once repaired!
I did similar a few weeks back, had to use a worm for first time. Was told to leave as is, then 2 weeks later it decided to just give up.
So my view would be to replace or at least back up with vulcanising glue when you get home.
Has anyone done a mushroom on a road bike tyre? I've got a cut on a fairly new tyre and it won't seal with sealant alone. I've tried an anchovy but once it was back up to pressure it didn't hold and spectacularly ejected itself. Having done one on a knobbly tyre it's easy enough to leave a bit of the plug sticking out but on a slick road tyre what's the thinking. Cut it off flush or leave a bit of stem to wear down. I don't want to be having to remove the tyre again cos I've ballsed it up first time!
After a recent puncture needing two thin plugs, I'm leaving mine in as I've only just recovered from my most recent Rimpact tyre swap battle. Trimmed the plugs down using a sharp blade after getting home, and added a bit of flexible glue from the outside.

Yes last night! I had a cut in the middle-ish of my front tyre (Corsa N.ext) a month or so ago that needed an anchovy to seal, but I noticed that the anchovy wasn't wearing down as I expected. I trimmed some of the bit that was sticking out on Sunday, then the tyre was flat yesterday and a couple of attempts at sloshing the sealant around inside didn't help, it just blew every time it got above about 40psi. So I whipped the tyre off last night and shoved in a small mushroom patch - fortunately the location of the slice meant the patch was nowhere near the bead so it wasn't much faff. I've trimmed the stem fairly close to the tyre, so will see how that feels later - the anchovy was sticking out a bit and I didn't notice that so hopefully the shroom is similar. It's still holding pressure this morning but I'll wait until after I've ridden it before declaring it a success.
Had one recently, won't quite seal even though a tiny tiny hole.. weird.. I've removed the tyre and used a wormy thing to secure it... I'll now give the tyre away. Which is pretty sad for me as it's a 2 ride old DHF. But we don't race on repaired rubber, so it's a throw-away
@thepurist - interested to hear your thoughts on the outcome. I'm awaiting some Rema tiptop mushrooms so can't move on it yet.
I assume it's just a case of cleaning and abrading the inside of the tyre and cementing the mushroom in place and letting it cure?
Well, lunchtime test ride completed without incident. Yes I abraded the inside of the tyre a bit (probably not enough), spread some vulcanising goo around then pushed/pulled the plug into place. Topped up the sealant, reinflated the tyre then snipped off the mushroom stem with some side cutters so it's a smidge proud of the tyre. I really didn't notice it at all on the ride - any feedback from the remaining stem was lost amid the usual chatter from poor road surfaces.
I patched a gp5000 with a regular inner tube patch and got another 1000 miles out of it.
It’s quick enough to do roadside in a pinch so I always take an old fashioned kit on long rides now.
That’s my only tubeless beef really, I’ve ended up tripling up on puncture repair stuff to carry 🤣 (tube, plugs and old fashioned kit).

Sounds promising then - I'll take my time fitting and hopefully get a decent result too.
<p style="text-align: right;">I gave up on tubeless after years without a puncture I got two on a road tyre, quite large to be fair, in quick succession and neither would seal. The anchovies were useless.</p>

How did you clean the sealant off the tyre?
I had a 6mm-ish flint slash to my GOne Bites a few weeks ago. I managed to get home (10km) with the tyres slowly going down but the sealant desperately trying to deal with it. I popped in 2 plugs when I got back. I got 2 more 50ish km rides done without any trouble. This week riding on a rough canal path (Grand Union) the tyre went again in the same spot. I guess the old plugs must have been ripped out. A few mins later, new plugs were shoved in, tyre pumped and I was back on my way for another 30kms to get home with an air tight tyre.
The tyre is now off, cleaned out and I've got a tubeless patch/boot glued inside drying (Velox tubeless tyre repair kit). I like the look of those mushrooms. I've had them used on a motorbike and car before. I didn't know they existed for bikes.
