Failed Mushroom Tyre Plug - Options?
Discussion
As above, I bought a car recently and noticed that one of the tyres is losing anything up to 10 PSI per week.
Closer inspection reveals what looks like a mushroom plug, the type that people can do at home. It appears to be leaking.
What are my options? I don’t see how I can get it out, so I am thinking to simply take it to a tyre shop for a proper wheel off internal repair.
Anybody been in the same situation? Must say that the diameter of the plug is quite large compared to something like a string repair. Hoping it can still be patched.

Buy a new tyre, it is safer than a repaired tyre. Personally I no longer repair a tyre I scrap it and buy a new one. But there again I do few miles so the chances of getting a puncture are not high.
I’ve repaired lots of tyres over the years with absolutely no issues. So I’m not worried about a repair, particularly if it is the best kind (an internally applied patch).cliffords said:

I had similar and couldn't get a tyre shop to re do it .
I bought a new tyre
Ouch. Did they say why and was that reason the mushroom plug in particular?I bought a new tyre

If you're used to making that type of repair and think it's a sensible option, there's nothing stopping you.On the other hand if you mean you're used to paying other people to repair your tyres then you may struggle to find somebody willing to do it, but there is nothing stopping you from asking.

What do you mean clean up the area? Sorry I’m not sure I follow. Would that be to get rid of any glue from the previous repair?
No you would sand the area around where the patch needs to go. The problem is the patch that’s there, you wouldn’t know how the object went in you would need to clean the area up, the chances of the second repair taking are low, you either end up with it failing while parked or at 70mph …. It’s not worth the risk.GreenV8S said:

Thanks for the expertise, sounds like you work the trade.
Have you confirmed it is definitely the actual repair that is leaking with water?
If it is a "mushroom plug" they can only be fitted correctly with the tyre off, and for someone to be able to do that at home they would need the gear to remove the tyre from the wheel, which is very unlikely.
Far more likely is the possibility that it is a badly inserted string type repair.#
Most likely a nail etc went in at an angle & it wasn't inserted through the actual hole made at the correct angle to fill the hole & so didn't fully plug the hole.
Pretty much as others have said, without having the 100% knowledge that any subsequent repair is actually going in correctly (which would now be difficult due to the failed repair) it is only ever going to be a replacement tyre to fix it effectively.
Generally in these circumstances it is also best to replace both at that end of the car so that they are evenly worn.

My initial thoughts were the same, but the term 'mushroom plug' seems not to mean now what it once did...

Probably still the same diagnosis from my viewpoint that aside.
I too always considered a mushroom plug to be of the take-the-tyre-off-&-apply-from-the-inside type & I've had a few of these done over the years without any issues:

But a quick bit of googling brings up something that looks like a button mushroom inserted from outside & has plenty of kits on ebay etc & the AA carry them - but note that the AA only consider it a temporary repair:
https://www.theaa.com/about-us/newsroom/innovation...
From the AA link: "The repair is rated for a distance of 100 miles and a speed of 50MPH."
