Temporary tyre repair (car, not bike)

Lasted me a few months before I got it properly fixed, including a 600 mile drive.

Not sure I'd risk it.  I'd probably just get it sorted asap.  

They last forever, I've sorted a couple of slow punctures with them. You've done the damage now, nobody will repair that tyre now you've jizzed in it so you may as well live with it.

Didn't work at all for me

I have one of those in the car.  I believe there are dire prognostications of doom from using it as anything more than a get you home measure at low speed.  Your can may vary.  I just wouldn't chance it and would be off down the tyre place asap. 

Where's the puncture, centre-ish of tyre or near edges?

If near the edges no one will repair it anyway and as said, a lot of places won't touch a tyre with sealant in it. "Because".

I would replace tyre ASAP.

“Because”.

Because of the time and risk involved.

If it's not an obvious puncture (i.e. not a big nail/screw sticking out the tread) then how do you find the original puncture to fix it?

Was it only a single puncture, or has the sealant sealed other smaller punctures, which then might fail once all the sealant is removed?

How far has the tyre actually been driven with the sealant in it? This contributes to the previous risk, that there may now be more than a single puncture. Especially since customers will blatantly lie to try and get as cheap a fix as possible.

It's bad enough cleaning all the sealant of the rim, but cleaning out a tyre takes a lot longer and even more consumables. Plus all the equipment will likely need cleaned afterwards.

Ultimately it comes down to risk, and cost. For cheap tyres, repairs aren't that viable (cost of labour alone is going to be £15-20 for a simple puncture repair).
Then there is the risk from a failed repair, both reputationally from the customers POV, and from an insurance perspective (automotive repairer insurance companies have really been clamping down on what they'll cover from a risk perspective), so from a respectable business POV, it's far simpler to say no, and have customers who want to take the risk, find a questionably insured repairer elsewhere.

That's like the old "fact" that you can't get repairs done outside the central tread. You can, it just needs to be a proper repairer you take it to rather than a fitter (who still might not be able to fix it but is qualified enough to know that) . Yes the gunk is a PITA and yes it's an extra cost but decent tyres aren't cheap either.

Thing is, if it fails, you only get back the exact same puncture you had before. So bear that in mind, if it were only going soft slowly then that's exactly what it'll do next time, if there's a next time. Especialyl since if I understand right it never actually went flat? Because in that case there's also no risk that it's taken knock-on damage. If it went down fast and scary then that's a different risk.

Thanks folks.

Sounds like if it has stayed up overnight then it might well stay up a while longer. This at least means I don’t have to spend today searching for an immediate fix.

Though it was just one rivet, removed, and it was away from the tyre shoulder I’m expecting to replace the tyre.

The like for like replacement is a surprising >£300 so I’m planning on getting the not-foam-damped version or something similar. The ‘regular’ version appears to be £100 cheaper and 3dB quieter 🤔

right before i took my landy off the road in 2012 for rebuild i got a flat while out and couldnt get the wheel off  with the tools i had to hand . i used a can of tire weld and bought a bigger breaker for future.

the landy snd for 3 years while i rebuilt it ... the other three tires were pancake flat when i removed them to fit new. the one with tire weld in was as hard as the day i parked it up.

I also used it to deal with the early 2000 s era  VW porous alloy issue that plagued their stock wheels. which it did admirably.

You'll struggle to get anybody to do a hot vulcanising repair on a road going vehicle tyre now due to insurance, even if you do manage to find somebody with the correct equipment and training. Insurance companies have restricted what repairs they'll cover, so unless a company wants to take the risk of knowingly carrying out repairs that won't be covered by their public liability insurance, they just won't do them.

Garages are even struggling to get insurance to cover fitting part worn tyres, or customer supplied tyres, so it wouldn't surprise me if easy tyre repairs will be next on their excluded list.

@mc Which is why I fit and forget noodles in my car tyres. Haven’t died yet.
Slow punctures with no obvious cause get a 50:50 water:Slime solution, again works fine, and the tyre repairers just rinsed it off the wheel months later at tyre replacement time.

@oldnick noodles don't meet the relevant BS standard though, so should something happen and your insurance company find out about them, they'll cancel the policy.

It all comes down to how much risk that an individual is willing to take.

Too late now but I’ve used a tyre worm on a similar puncture, just to get me to the tyre shop for a repair. Double puncture (both offside tyres), so although I had a full size spare, I’d still be stuck.
Decent track pump is so much better to use than than the foot pump I had in the boot too.

Could possibly also have left the rivet in the tyre and topped up the air to get you where you needed to be/tyre repaired.

Anyone tried the Dynaplugs for car tyres yet?

Allegedly they are a permanent fix. (In France at least)

I’ve used a dynaplug on a car tyre, on the shoulder so new tyre or lengthy repair so I was willing to give it a go…

Got us locally mobile to the tyre shop the next day.

Dynaplugs aren't a BS standard repair.

I've had no issues finding someone to do hot vulcanising or just a bog standard repair in the last year, I'd like to know why you think otherwise.

This would have been my plan. But losing 0.7 bar in a 3 mile drive and seeing the air bubble through the rain around it suggested it would have been flat by the end of the zoo lights walk.

Have certainly driven with roofing nails stuck in tyres for longer in the past.

@squirrelking
l’ve not had a problem getting tyre repairs done, but a Dynaplug is something you can carry with you and do at the roadside - an advantage in areas you don’t know or out of hours.
Given the French have allegedly approved them for use as a permanent repair, and given their 130k speed limit, I’d have thought they’re pretty decent.
I accept probably not a repair recognised at present by UK authorities, but I do drive a few thousand miles in France most years, normally with a schedule to hit.
I was interested in other’s experiences using them.

Sure, I only mentioned it since it's worth considering whether your insurance would cover it at best and the legal implications at worst. FWIW I looked at them in the past but decided I didn't want to risk it for that reason.

It seems daft but sometimes it really is a case of just because someone else thinks it's safe doesn't mean it is. I have absolutely no reason to suggest it's not but given some recent experience of French safety points of view in industry its not unreasonable to treat things with caution.

I note the references to the French being ok with it appear on the American website (and have been detuned since I originally saw them) and not on the UK website. 

My car only carries an electric inflator and a can of goo, but to be perfectly honest, if I had a tyre go flat on a motorway or dual-carriageway, I’d call emergency breakdown, because there’s no way I’ll try sorting out a flat tyre on my own under those conditions.

Otherwise, if the tyre was gradually going soft, and I could see where and what the problem was, I’d try to pull in somewhere and over-inflate it and try to get to the nearest tyre centre.
Any puncture on the shoulder of a tyre, as far as I’m aware, and I have asked the tyre fitters where I used to work, it’s not possible to safely fix it and they’d junk the tyre. They were fitting tyres to most vehicles, up to and including Mustangs, high-end Alfas, Teslas, etc, so I’ll accept what they told me.

For clarity:

Most tyre fitters will only repair minor problems. You can have major problems repaired, but that's a specialised job that will involve more time, effort and cost. Major repairs will be marked inside the tyre with the repairer's identification
