View Full Version : tyre sealant - opinions?
Anybody experience with tyre sealants, you know the stuff that you put inside your tyre then leave. When you get a puncture, its leaks outs the hole and then forms solid to block the hole.
Any thoughts? pros/cons...
Is it worth the money considering it'll cost roughly the same as fixing a puncture?
Does it bugger up your tyre?
Does it last more than one puncture?
Does it freeze inside your tyre in winter?
Speed rating?
Too many questions?...I'll give you some time to think about it...:)

yes
no
yes
no
same as tyre
not really
actually the stuff i used to get was wicked , just for a demo i punched a sharpened scrwedriver through a tyre 35 times , it lost 2psi of pressure overnight !

Not sure what stuff your going to use, but the stuff i've seen (priced at around £7) is limited to 50mph, and is only supost to be a temp measure!
Personally I would never use this stuff especially in our cars and the way they get driven.
Ive worked in a garage for 7 years, seen all sorts of blow outs and 1 due to a fill up off the foam stuff. A puncture is no more than a tenner so get it done properly.
Safety reasons more than anything.

are you saying that if you have a puncture you dont need to replace the tyre? say if its a nail through the tyre... even on a performance car?
only 7 years m8 , lucky you ! the stuff i am talking about is not tyreweld ( that is supposed to be a puncture repair stuff , the stuff i am on about is a puncture preventer , it is already in the tyre before the nail or screw or screwdriver blade or in one case a spanner :eek: :eek:
this stuff will seal the hole preventing pressure drop and in most cases blowouts coz the tyre wont run under pressurised and overheat and therefore blow out !
now a question for you just to test your tyre knowledge ?
what is the british standard for the maximum number of puncture repairs in a tyre ?
shadow , no i am not saying you will not have to have the puncture fixed eventually ( or the tyre replaced ( or the tyre replaced depending on the position of the puncture )) but what it will do is seal the hole until you do your weekly tyre check ( i presume yoe check and deflint your tyres weekly especially as its a performance car !
cheers guys,
So it will keep the pressure for while, thats what I've seen demonstrated quite impressive but unsure of speed rating, which you've answered.
However, you say you should fix the puncture properly once discovered...but what I've heard is that once that stuff is inside, the tyre is pretty much dead and cannot be fixed...hence new tyre. I was thinking, can it just stay sealed up and don't get the puncture fixed, until you need to replace?
To put this into context, there's a slow leak in me tyre. Now instead of forking out tenner to get puncture fixed, get this sealant stuff inside. It'll (hopefully) cure the leak, and prevent future blowouts, if I can leave it in forever and continue to keep driving as normal. However, if I can't leave it in forever, my tyres buggered because they can't repair it so I've wasted the cost of sealant plus need a new tyre.
God, I sound so cheap...:rolleyes: for the sake of a tenner.
Aah, bugger it, I'll fix the leak as normal...and not worry about this.
Apologies to anyone following this far down...:)
give me the name of the product and i will investigate and report back , but if it is tyreweld dont bother !
QUOTE-but if it is tyreweld dont bother ! Carnut we agree on something then;) From your description I thought you meant tyre weld.

I dont know but if I wanted to be flash I could have found out and then answered. Ive never claimed to be a bag of knowledge just stated that as a mechanic Ive seen some bad accidents caused due to blow outs and dont trust any tyre foam crap.
If I had a nail in my tyre I wouldn trust some foam to repair it for me, I d rather know it was there and fix it properly. Plus if your going to use the foam you need to do all 4 wheels, isnt it just cheaper and safer to repair the punctures when and if they happen??

wasnt being awkward , just trying to show that i was not talking about tyreweld without mentioning a brandname !!
its more like ep10 ( viscosity ) antifreeze (colour)
we tested it on 150 mph mercs , no probs !
now the **** bit . i cant remember the brand name :confused: :confused:
the answer to the british standard q !!!! as many as the tyre will take without the plugs oir patches overlapping :eek: :eek: :eek: :eek: what this does for the tyre structure i would not like to know ! but i have repaired some very illegal punctures in my time !!!!
cheers for a good debate m8
Game set and match.
Result, a draw for arguments sake:D

a definite vote from two experts against tyreweld :D :D :D :D :D :D
When I was at my last job I had to do some editorial for a company who marketed something very similar.
To test it, they put the stuff in a tyre, got a Plod out of bed and shot it with a proper .22 rifle. (bear in min this was a fully documneted test).
The tyre lost appx. 0.5psi and then sealed itself... Can't remember the name though...

Could you be referring to ULTRASEAL, I was considering this stuff when I got my new Toyos.
Dealer said that it would reduce impact of a serious blow out at high speed, ie stop tyre shredding since the 'goo' inside is pushed out by the air to imediately seal puncture. Thought this might be a possible lifesaver in the (albeit unlikely scenario) of blow out at 150mph.( Stuff is supposed to be tested up to this speed).
I was told however that it was unsuitable for ultra low profile, 'rimmed' tyres, (not really sure what that meant but I guess it would certainly rule out those with the 18 inch wheels and such), Jury is still out on this one for me I reckon.:confused:
My Safrane came with a can of tyre sealant in the boot instead of a spare wheel and I had the tyres filled with sealant. The only time I had any problem was when I drove into a pothole on a road in Wolverhampton, which ripped a chink out of the tyre and wheel. Obviously, sealant was no good at all in that situation and not having a spare wheel I was a bit stuck. AA didn't want to know because the car didn't have a serviceable spare so I had the abandon the car in Wolverhampton at 2am :( :eek: .
Got it sorted, next day and then went round to my renault dealer to order a spare.
Moral of the story being there ain't no subsitute for acrrying a serviceable spare (even a space saver).

Tyreweld and it's copies, are as get you home measures, same as a space saver.
You fill the tyre with the stuff, drive it slowly to nearest garage and inflate.
But you have to get the puncture repaired pronto.
Don't know whether it is the same stuff, but you can get similar puncture sealant for mountain bikes. I think it is called gloop or something. I tried it once and as far as i can tell it wasn't much cop. It made wheel a shed load more weighty and when i found a thorn in the tyre i pulled it out only to get a face full of green gloop stuff and, after rinsing my eyes out, a flat tyre.
Not heard about the stuff for a car but i imagine it works on the same principle, if it helps prevent blowouts it might be a good idea but i would be a bit sceptical.
I was watching...errr, channel hopping onto QVC *cough*...
I saw the demonstration of this tyre sealant. Its like a runny lquid in a can, which you put into your tyre like air.
Then when you're driving along, it coats the inside of the tyre (contrifugal force). Now when you get a puncture, they demonstrated by driving army trucks/cars over planks spiked with 6inch nails, the sealant immediately comes out the hole (due to air pressure) and hardens to form a plug.
Now they didn't mention anything about whether you need to fix the hole properly or that you can carry on as normal as though nothing has happened.
The stuff is called Super-Guard Tyre Sealant...no other branding can be seen.
The blurb says:
Help seal punctures with this permanent and strong air tight seal. With its multi-sealing capability, it helps to minimise the need for puncture repairs and new inner tube costs.
QVC:rolleyes: What are you like eh???
Seriously this stuff is crap, im not just saying it but I have first hand experience with it. Personally I hate it and when I MOT peoples cars and see a can of this junk in an empty spare wheel well it makes me laugh.

Surely if the stuff you put in before getting a puncture (as opposed to the seemingly completely different stuff you put in after ) was really much good, the tyre companies wouldn't have spent all the money they have on developing highly sophisticated run flat tyres??

Yes, I was thinking the same.
I guess there is a market amongst people who dont have run flat tyres though, I first saw it demo'd on one of the motoring progs, (driven, fifth gear or somthing), a year or two ago, they did seem to be impressed by it.
The 'ultraseal' stuff is not somthing you buy as a DIY thing, there are dealer/tech type guys who come round to your house to put the stuff in (about 10-20quid per tyre in my area), the one I spoke to didn't seem to know a lot about performance tyres though.
