Goop preventative tyre sealant
Discussion
Hi all! I had a piece of sharpened flint punch through a tyre on a light off road track in my Audi Q7. The stone was stuck in the tread so I was able to get somewhere safe and have the RAC come out. They plugged the tyre and stated it needed to be replaced. The next morning (I was staying away overnight) the tyre had lost pressure. So I used the sealant repair and compressor kit as supplied by Audi (Slime is the brand). It sealed the puncture (or perhaps a secondary one that the RAC and I had missed) and got home.
As the tyres are part worn, I have to rather expensively replace all four. And I want to fit something more mud capable than the Hankook Ventus Evo S2 that my car is supplied with.
I also came across a product called Goop, which is designed to go into the tyre when new and will seal smal punctures on the tread as they happen. It is supposedly TMPS safe, so won't bugger the monitoring system.
Question - has anyone used this stuff? And I mean specifically Goop, as emergency repair products like Slime are meant only to get you home, not to live in the tyre...
My car does limited mileage, so the stuff would pool in the bottom of the tyres over time. Also I have two sets of wheels and tyres (summer/mud and winter/snow) , so tyres would sit on their side in the garage for months on end with the Goop in them.
I will call the company in Monday, but thought I'd also ask the collective for experiences.
This is the car, as it is PH...
And 20 inch winter wheels shown below as the 22 standard fits have tiny sidewalls that I do not love. 20 is the smallest I could go due to the size of the front brakes...but I should get a nicer ride. To be fair, the car has air suspension and rides very well on the 22s, so I am probably being silly. I'd want to Goop these as well, for winter trips to the Continent.

The issue I have had with using products such as goop is that when you have something like a screw stuck in the tyre the tyre repair places say the puncture cannot be fixed. I presume this is because all the goop would need to be cleaned out before they can apply a patch and they don’t want the hassle of doing that.
The stuff works to stop the air escaping but then makes a repair difficult so steers you towards having to buy a new tyre rather than having a repair.

I don't know about Goop, and whether it's a permanent fix, or if it's just to patch a puncture until you can get it repaired, or the tyre replaced. I'm not sure if I'd feel comfortable with it as a permanent repair.
That said, if you're looking to replace four tyres, you might want to have a look at National Tyres. According to their website they offer a gurantee against accidental damage to the tread or sidewall for the lifetime of the tyre, for £7.50 a tyre for tyres bought from them.

Good point. Goop supposedly washes out easily, so I may speak to my local independent tyre shop to get their view...
You can buy self seal tyres, quite a few of the top brands make them. The self sealing layer doesn't slosh around like goop either and they can be repaired as normal.https://www.pirelli.com/tyres/en-gb/car/tech-and-k...
If you're that paranoid about getting a puncture, then buy either runflats, or seal it type tyres.
I wouldn't be overly keen on some of the crap you put into the tyres. But also, carrying a DIY plug kit with you is not a bad idea either. Certainly a lot easier than faffing about with spare wheels that are also flat.
And Jon covers such things very well with his latest video. The internal seal it seems pretty good !

Although maybe some sort of test of the various DIY internal goo's might be a good idea. Not sure if there is anything on YT already

My worry would be an object entering the tread or shoulder at an angle, without the product mentioned the tyre would deflate and be dealt with, but if the product did its job that nail/screw/whatever could be stuck indefinately in the tyre and on every corner cutting through the inside of the sidewall leading to possible rapid sudden deflation.

If something goes through the sidewall, it's screwed either waystevieturbo said:

Completely missing the point.If the sealant does the trick and prevents the tyre deflating the object that's gone through the tread can easily spend the next few humdred miles gradually slashing the sidewall unseen.
Without the sealant almost certainly the tyre will deflate.

Pretty much no crap inside the tyre will seal a sidewall hole anyway, as the stuff will not be forced to that area. And it would be very unlikely for something that is large enough to pass through the tyre and end up inside that could cause harm...for it to go un-noticed in the first place.If the sealant does the trick and prevents the tyre deflating the object that's gone through the tread can easily spend the next few humdred miles gradually slashing the sidewall unseen.

Such sealant produce are intended only for small holes, nails etc. Not large holes, and not in sidewalls.
And anyone using any product to try and self seal anything, should obviously have TPMS onboard.
I use Goop on one of my motorbikes, because it runs inner tubes, so I can't plug holes at the roadside.
I've had a set of tyres replaced and the same tubes put back in, complete with Goop still in them. Valves are OK, but I don't have TPMS.
No idea if this is any kind of help or recommendation, though!
Personally, for tubeless tyres, I carry a 'sticky rope' repair kit to get me home.

What happens is thin bolts, screws, nails, general debris enter the tread, not the sidewall, and protrude through but because they are generally round objects they partly seal so the puncture is slow but noticeable, very often the object will be pressed deep into the tread by the weight of the vehicle...seeing how many drive around with almost flat tyres (unless the car tells them) or with bald sections the chances of the car user spotting a nail imbedded are slim at best.Such sealant produce are intended only for small holes, nails etc. Not large holes, and not in sidewalls.

These foregn objects can be inches long, and if they enter at an angle or straight but near the shoulder can cut a decorative arc swathe through the sidewall over the next few hundred miles.
I've seen many examples of this type of thing because i started work a lifetime ago not as a tyre fitter but in a tyre repair workshop, i for one want a tyre so penetrated to go flat so its removed and the inner carcass inspected properly, not to be sailing merrily along at speed whilst some now sealed in place 4" no 12 screw chews its way gradually through the nylon sidewall cords.
Actually, thinking about it, the large piece of flint I had in the tyre would not have been noticed by me but for the TMPS and the hissing when I stopped to check. It was on the inside of the tread so not visually obvious. And I would have driven for miles with the small air gap around it sealed until it one day it punched entirely into the tyre, probably causing a blowout if I were at any speed as the hole would have been too big for the Goop to seal.
I think I've answered my own question, but would not ha e got there without this thread. Thank you chaps.

Some people report wheel imbalance with goop preventative sealant.
Get yourself one of these and watch some YouTube videos of how to use it:
https://www.amazon.co.uk/s?k=Tyre+Doctor+Tyre+Punc...
There are 1001 types on Amazon or eBay from the sticky strings to mushroom plugs.
Some people say you will die if you use it, but that could happen with the standard car goop. There are plenty of people who plug them and drive until the tyre is replaced. Just get the tyre repaired ASAP.

I have a MB A220 and suffered my first flat. First time with no spare and used the Tirefit sealant which got me home. Went to a main repairer who said due to using the sealant theyt could not repair it and I needed a new tyre. Thought I was being scammed so went to my MB who confirmed I needed a new tyre. Tried another two and got the same response so went home to do some research. The MB Tiyrefit does say to junk the tyre after using the sealant. Wynns and Holts both state that the tyre can be repaired after using their sealant so not all sealants are equal. Waiting to hear from MB as to why they supply a fluid that mandates the tyre must be thrown on the scrap heap/tyre mountain. Not a good eco policy. In addition, they wanted £57.80 for a new can of 350ml sealant. I opted for Holts Tyreweld at £8.99 (500ml) which will do just as good a job but will allow me to get a repair done (if I can find a repairer willing to clean the sealant - and I would be willing to pay a charge for it). MB process would cost me £220 for a puncture and Holts around £40 plus a small charge for the cleanup. Now let me think .......
Interesting the cost of a new bottle of the sealant. On our Volvo the sealant had passed the use by date. Never picked up by the full Volvo service regime.
60 for a new bottle. eBay and Amazon do the whole kit including the pump with OEM branding for around 40 pounds.

I would also be concerned about the effect on handling.
As well as unbalancing the wheels until up to speed, it's more unsprung mass in each corner.
My car doesn't have a spare and the pit of goo passed it's expiry date, but it looked ok.
I now carry a little sticky string set that also comes with a few tools to insert the string, and a can of Holts squirty cream.
