A two day saga and a lot of ball-ache because Ford couldnt stick a space saver in the boot, or even tell us that there wasnt one in there in the first place. So when im asked about tyre goo I get a bit twitchy

But are illegal in the Uk and much of europe because they are known to be dangerous. You can buy them, but it's illegal to use them over here.

Yes Puncturesafe tells you you've had a puncture by showing a blue marker on the tyre. If you notice a screw or nail in the tyre it's vital to remove it to prevent further damage to tyre bands. If you had followed the correct procedure to remover the screw, no doubt the hole would have sealed unless the hole was bigger than 6mm. I've never had even one puncture not seal with Puncturesafe. And I've had plenty of punctures when covering up to 40,000 mile a year for several years on various bikes. Riding in India it was common to collect several punctures each month! Thank goodness for Ultraseal as it was then that I was using.MrGrumpy wrote: ↑Fri Aug 28, 2020 10:36 amI think if it works, the gunge seeps up into the whole and solidifies, so since its normally a lurid pink or green, you can spot it by examining the tyre. Of course, in theory, you don't have to know that it works - that's the point! The trouble may come if you see the nail or screw or whatever that has caused the puncture being still in the tyre. I was never sure whether you are best leaving it there or not. Once I found a huge screw in my (gunged) tyre and foolishly removed it, with the result that I got a flat tyre in 3 seconds, and was then firmly up shite creek without a paddle......
Yes those are conventional vulcanised "proper" tyre mushroom plugs. They are legal but instantly impose a speed restriction on the tyre of 85mph. Heat can cause those mushrooms to fail that's why they have a speed restriction on them (yet they still fail). But as you say they can last the life of the tyre. Some folks on here are talking about the mushroom plugs inserted from the outside of the tyre. Those are not a legal permanent repair and are known to be dangerous. There is also a speed restriction on them of I think 50mph.Pandrop wrote: ↑Fri Aug 28, 2020 9:38 amThe mushroom plugs that I have used have always been pushed outwards from inside the tyre and have lasted the life of the tyre. That said I suppose it depends on the severity of the puncture, im both my cases it was a small nail hole which was then drilled out by the repairer then copious amounts of glue and a wide-based mushroom pulled through with pliers i.e a proper job. As you rightly say anything applied externally would be a temporary fix.MrGrumpy wrote: ↑Fri Aug 28, 2020 6:23 amWell, there are outside and inside plugs/mushrooms. The ones applied from the outside (as done by the AA in my case) are intended as a temporary repair, with at least theoretical limits on speed when fitted (these are the sort I found are pushed back out if you have puncturesafe or whatever in the tyre and it doesn't work). However, I've heard of people leaving them in for extended periods with no probs. There are also the plugs that fitted from the inside, which are intended to be a permanent repair.
I've had failures....and in the case of the aforementioned screw, the gunge was only slowing deflation. It was a huge thing - I clearly did the wrong thing in removing it, but the subsequent deflation was so rapid, I doubt that the gunge would have anytime to work if I had used the correct procedure.Data wrote: ↑Fri Aug 28, 2020 3:22 pm If you notice a screw or nail in the tyre it's vital to remove it to prevent further damage to tyre bands.

Reference the instant 'goo' you speak of in the Ford car. That's a pain but it's a completely different sort of goo to Puncturesafe. Puncturesafe lives in your tyres permanently, sealing any hole straight away. It works for most punctures if folks follow the instructions. That tyre goo in the Ford also usually works ok but folks don't follow the instructions so end up with an empty tyre! And once you have used that instant tyre goo you cannot then have it repaired using a conventional method. The tyre is junk. In contrast, Puncturesafe does let you have any puncture that it has sealed repaired in a conventional manner should you wish to do so. But why would you. Puncturesafe is far superior to traditional methods and permanent. It'll never leak again from the same place ever. Have it conventionally repaired and it immediately has a speed restriction on that tyre and always the risk of the repair letting go at some future time. Regarding corrosion, I've used it for 25years in bikes and cars and in the army we used in in combat vehicles, and I've never seen any corrosion. I worked in the trade for many years too. Puncturesafe is the most prolific puncture sealant pretty much in the world along with it's name sake Ultraseal. All Royal Mail vehicles used to have it in until they started to economise, and pretty much all the big fleet operators have it in their tyres. None of those things apply to Puncturesafe. Just saying, again!![]()
