It's utterly unsafe

Why is the tyre, the puncture in which has been sealed, and is presumably successfully remaining fully inflated ("still o/k") "utterly unsafe"? In what way? Do you think a punctured then sealed tubeless tyre used in a bicycle tyre is similarly "utterly unsafe"?

They're at best a temporary get you home fix. And they usually render the tyre unrepairable on cars. Your daughters car needs a new tyre. Like, immediately. It's utterly unsafe and I don't want to share the road with it.

Then you may not be using the road much longer as these are now common place and as i said all new cars come with them.
If a tyre is repaired in this method and has been a success for nearly a year whats the problem.

In this country they are deemed to be a temporary fix. In other countries, including Germany, they are regarded as a permanent repair.

 

[TheDoctor]

I can't find a single source that says they're anything other than a temporary fix. BS AU 159 stipulates that a permanent repair involves removing the tyre and checking for interior damage. You don't know if that's there or not. As such, they could deflate at any time for all you know, and an instant flat at motorway speeds is utterly unsafe. And yes, my car came with one. It's now got a space saver wheel in the boot instead.

I'm going by what I've read on a motorcycle forum where people have stated that the advice in the BMW handbooks differs from what they print in the UK version.

I can never understand the term space saver. What do you do when your car is fully loaded and you have to change a wheel, plonk the full size one on the wife's lap?

 

[TheDoctor]

Roger that, SJ! It is especially daft in the Audi TT, where the space saver slots upright IIRC. The road wheels won't fit in the gap!i

 

[Pale Rider]

A mate of mine had an older Ferrari which had a spacesaver wheel and tyre mounted on the top of the engine.

He discovered there was no way to carry the full size wheel, it wouldn't fit on the engine, or even on the unoccupied passenger seat.

Newer supercars have run flat tyres, but if the tyre is badly slashed it's a recovery job.

 

[TheDoctor]

That is a monumentally poor design decision. May as well not have the spare, surely? Anyway, we digress. Personally, I'd use a sticky patch and carry a pump, rather than a squirty tin, but that's just me. I'm sure for widish tyres it'll be fine.

Im not sure where some of you live, but maybe you should move.

Some of us like to live in the same country as our relatives and try to improve it

2 inner tubes and a can of sealant sounds excessive. But all my bikes but one have Schwalbe Marathons and I cannot remember my last puncture.

Yeah, if you're happy doing that much extra work to overcome draggier tyres every ride, punctures will probably be rarer.

I used that type of sealant on a moped years ago. It leaked everywhere, what a mess.

I hate mopeds as much as the next person and would be happy to seal one up, but try using it on a tyre next time

 

[Cuchilo]

without the disadvantages of having sealant in the tube all the time.

and the disadvantages are ?

 

[mjr]

and the disadvantages are ?

OTTOMH it's a little extra weight in the tyres, it seals the valve eventually, it sets in the tyre eventually and if your tube gets cut (rather than a small puncture), it's very messy and a swine to clean off what it sprays.

 

[Yellow Saddle]

and the disadvantages are ?

Wheel balance. A lump of sealant in the tyre often doesn't spread evenly and causes an imbalance. As you know, an imbalanced wheel causes steering or arse shake, damages the tyre eventually and is bad for the suspension.
Some sealants jamb the valve, which you only discover when you want to top up the air some time down the line.

I don't understand why sealant renders the tyre unrepairable. Admittedly I've never inspected the inside of a tyre treated with the sealant supplied with some cars nowadays but sure it is just a matter of removing the tyre, cleaning out the sealant and fitting a mushroom?

 

[TheDoctor]

Me neither, but I'm not a tyre repaired.

Some sealants are latex-based, so "cleaning out the sealant" means you're trying to remove rubber from rubber which doesn't seem like the easiest thing - and the other additives might prevent the repair bonding.

Some sealants are marketed as washable so that the tyre can be repaired conventionally - the RAC's is one.

Websites discussing car repair canisters seem to be full of wailing and gnashing from motorists who discovered that their beloved vehicle isn't 100% invulnerable, these kits (now used by Ford and Vauxhall instead of spare wheels in some models) can't fix every possible tyre damage and they were too foolish to have fallback plans for their travel.
