Tyre weld, et al

There are various things you can buy that claim to repair punctures with just a squirt from the magic can; some even make claims to future prevention, which I find less convincing.

Does anyone have any experience or knowings of any of these?

I find little to recommend them more than an AA man, when you have a blow out at the side of the motorway.

Oh sorry I forgot - some divvi people buy cars without spare wheels don't they ?? Confused Rolling Eyes

I dont think any claim to prevent punctures. Just to fix them as they happen. On a cycle tyre I think thats ok, on a road vehicle tyre less so.

Stopping the deflation is good but you then dont know that you have a puncture that is temporarily being plugged by the goo. Long term I would worry about water ingress which is the reason for the mushroom type plugs they use now instead of patches.

I have used this stuff in quad & tractor tyres.

Re divi's buying cars without spares. Sadly more & more new cars are being sold with no spare. The ones that do have a spare have a space savers with a wheel well that you cant put a full sized wheel into. Right pain with a full boot & no space to put the flat full sized tyre. Also a pain for me as I have to have a full sized spare on the driving school car as space savers are not allowed on test as you are limited to 50mph & a test car must be able to keep up with the traffic.

i always use the squirty stuff in wheel barrow tyres and green slime in bike tyres.it works.

motor vehicle tyres is not my field

The preventative/slime stuff certainly works on push bikes. I'd be dubious about the effectiveness in a steel carcassed car tyre.

The repair stuff works as it says on the tin. It won't plug massive holes. AFAIK once used on a tyre, that tyre cannot be repaired, so best not to use unless absolute emergency or if the tyre is already at end of life.

The tyre in question has only a tiny hole, but in a place where it cannot be repaired (or so says the tyre dealer). It has plenty of tread so I am reluctant to accept that nothing can be done.

Sorry, I only know about the mower wheels, but we have never then managed the 7 odd miles it says you need to drive once it has been squirted.

I had a puncture recently, without the spare, in my newish car.

The squirty stuff was no good, as it was a slit in the sidewall. My OH was a star and rescued me, collecting puncture, getting tyre replaced, and returning back to me. I was left with 24 chickens sitting at the side of the road whilst he did all that, on a hot day, in the middle of nowhere, but with better internet than we get at home!

I have since bought a space saver.

If you are wanting to "bodge it" HL (and I can appreciate why you would )

I'd but a piece of tyre repair rubber from a different garage - (a bit like catapult elastic) and if you can get some glue, that too - Then I'd poke it in through the hole and let the compressive force of the rubber form a seal.

Naturally I'd only use this on something non-critical - like a wheelbarrow.

A can of the foaming goo fixed my tyre that had a blackthorn thru the side wall. It also fixed a leak around the rim. Should work if the hole is small. Anything bigger and it is probably a safety risk. Either way I didn't tell you to do it (backside covered).

Anyway, the can price is probably worth a try when compared to the price of a tyre.

That was what I figured, but the question now is: which goo?

If it's on the side or shoulder then the goo I've got states it shouldn't be used. It also states it's only a temporary fix and drive at a max speed of 30mph.

I would expect if you had an accident you wouldn't be insured. On the other hand you might save yourself a few quid until then.

On the mower we always use Tyre Weld RichardW


but the question now is: which goo?

If this a tyre on a road going vehicle then:-

No the question is why do you not trust the advise of the professional that has told you it is unsafe to fix the hole due to its location?

By bodging this not only are you risking your own life but the lives of everyone else on the road.

Goo is a get you home or to a garage temporary fix.

If the tyre is nearly new with loads of tread & not a cheap make or cheap size then ask them about sending it away for a major repair. Expect to pay 20-40 for this.

If this is a non road going vehicle:-

Then get some tyre repair string & a fitting kit of eBay. With enough string you can fix large holes.

Once when on a day out to a quad bike track one of our quads (the staff use only one for recover of customers quads) holed a rear tyre. The hole would take two fingers. We used string on the day as a fix so we did not have a quad down all day expecting to have to keep blowing it up. In the end the one fill of air was all it needed & we never did change the tyre or do a more perm fix as it worked so well.

In the past I have bought as a DIY Repair Kit the same device used by the tyre repair shop. The kit included an awl type tool, rubber, solvent and glue.
The awl was used first to clean the hole, solvent then glue applied, rubber inserted with awl. 10 minute job.
Not for walls only tread area. I've successfully used this method on holes caused by nails.
Kit still available, enough for about 10 repairs, less than a fiver.

He didn't say it wasn't safe, he said he couldn't do it.
RichardW

No the reason he could not do it was due to the location of the hole being in a non repairable position.

The reason its a non repairable by normal methods position is due to it being unsafe.

Only the central band of the tread is fixable due to the extra stress on the repair if its on the side wall or edge of the tread.

If its unsafe for a properly fitted mushroom patch then is deadly for a bodged goo repair.

Do you really want a blow out at speed?

Yes its a pain when a new ish tyre gets damaged & is not fixable.

Its a real pain when a bodged one blows out & kills or maims you / someone else.

Either get it fixed properly via a major repair or get a new tyre. Its not worth bodging it.
vegplot

Balancing the cynicism of the dealer wanting to sell you a new tyre or risking a potentially life changing event I'd go for the new tyre option.

He didn't say it wasn't safe, he said he couldn't do it.

Whatever you decide, there is no way you are going to get anyone on here or elsewhere to say that a bodge is going to be safe if "the expert" has refused to bodge it already !

One of those times when you just have to take responsibility for your own decisions Laughing
