My wife had a flat tyre yesterday. No problem, I thought, there's a can of tyre sealant in the boot. Being nice I drove out to do it for her and picked up another can on the way. 2 cans of tyre sealant, topped off with a small compressor.
In the 3 miles home tyre completely deflated and is ruined. Do these things ever work?????
I've only ever used tyreweld for an elderly set of alloys that were prone to leaking round the rim, it fixed them fine. I don't think I'd try it for more than a small nail hole in the tread tbh, what was the damage to your tyre?

Is that what the instructions say to do?
I couldn't see any nails or other damage but it was starting to get dark.
I've used it several times with good results.
Similar to above - to cure slow leaks caused by old, corroded alloy wheels that didn't seal to the tyre bead completely.
Does it work Yes, of course it does. Used it (OEM stuff in the car, not Holts) a number of time over the years. Though I've bought some Slime car sealant, as it's not supposed to ruin your tyre, like most other options do.
Thanks - just unlikely I guess

It was ruined as you took the sealant to it. It got you home so it's done its job.
I was vexed to find my new lease car came with this stupid system despite me repeatedly asking for a spare. I speculatively spoke with Quik-Fit about it and they said they wouldn't touch it, it'd have to go back to the dealer to be cleaned up and replaced.
Typically then, I got halfway to work one day to find myself with a slow puncture. No problem, thinks I, I have a compressor in the boot! Except, the compressor connects to the can of monkey semen and then the can connects to the tyre, there is no way to attach it directly to the wheel and use it just as a compressor. How dense a design is that? Luckily there was a garage just round the corner so I limped it over and put in enough PSI to get me home.
Ah home I then ignored it for a few days to see if it went down again or was a one-off. Predictably it did so with a heavy heart I rang the assistance line thing that comes as part of the lease. This was at home on a Saturday afternoon in the early days of CV19 so I was fully expecting to be told they'd send someone round on Monday. I was pleasantly surprised to be told "he'll be with you in half an hour," amazed when he was here inside of ten minutes and absolutely astonished when he'd fixed it and was on his way in another ten.
Moral of this story: if you don't have a spare wheel I can heartily recommend an AA membership.
No, they don't always work. I carry a can like that, and have a fancier tyre inflation system pump thing that plugs into a lighter on a car that is too svelte/ petite to have a spare wheel. I have only had 2 occasions where I've needed to use it, on 2 occasions it failed to seal the hole...or what could be more accurately described as 'gash' from dry stonewall stones or mohassive pothole. So 100% failure rate for me.
RAC cover is my tire fixer...far from ideal, long expeditions from base are a bit of a gamble. Next car may be more sensibly skewed to the duller end of the fun/practicality quotient scale.
Only ever used it once, OEM VAG stuff, worked well enough, wrote the tyre off though. Did you roll the car forward slowly to evenly disperse the sealant or did you whack it in and drive off?
Ive used Holt's and ive successfully had tires repaired afterwards. But then I have a good relationship with a local garage.
Good little scam that though automatically saying your tires a write off with once sealants in it.

Good luck
VW Touran, fun car, no spare !
I believe the tyre is written off if you use it as the garage will not clean the tyre up to repair it. I wouldn't buy a car that didn't/ couldn't get a spare for (although that might change if most car companies go down that road)
Heading up today for FIL funeral
Found the zafira had lost load of pressure in back tyre, found a screw in it ,
Got the tubeless repair kit from my camelback ,plugged it, drove 100 miles
Result!
Cyclists used to tubeless must have a better success rate with these sealants. Jack it up and get the wheel spinning to get the sealant about.
And sod letting the garage write off a good tyre, I'm sure I could get a car tyre off to clean it up with a bit of effort!
I did use a screw in plug last time as it was a very new tyre and I didn't want to waste the car sealant. Had to try two garages as the first tried to imply the screw in plug had enlarged the hole too much, robbing gits (it wasn't too big but thry wouldn't accept that the snapped off bit was wider than the bit in the tyre)
Had the tyre replaced today. Hole was in the sidewall so the tyre would have been a write off anyway. That's probably also the reason the sealant didn't work - nothing to make it climb up to the sidewall!

I tried it once. I gave up after 3 hours, having made some substantial gouges in the alloy wheel.

Problem with this is cars don't come with jacks these days. You can of course purchase a spare tyre kit from the OEM that comes with the usual scissor jack thing and tools, but nowhere to store it as cars no longer come with spare wheel wells. So you've got it rattling around taking up space in your boot and becoming a lethal projectile in the event of a car accident - don't fool yourself a few bungee chords or straps will contain it.
I have to admit that the best system I've actually experienced, even more convenient that a proper spare, are runflats. The wife has them on her car and she casually told me she had a warning light on her car for a couple of days, I looked into it and a flat tyre and the warning was the tyre pressure warning. She had been driving on it for two days (only the work commute) and hadn't noticed anything untoward in the handling of the car or the way it drove and just assumed the warning light was for washer fluid or something (don't get me started!). It then took another couple of days to get a replacement tyre in as for some reason the exact same tyre was out of stock everywhere...so we drove on it for another couple of days. Drove fine with no adverse handling effects even at reasonable speeds. So for that reason even beats a proper spare wheel as you don't have the inconvenience of having to replace the wheel at the side of a road...just drive into the tyre shop and get a replacement.
