Tyre sidewall repair?

[marcg]

So I hit a kerb (top skills there). And my sidewall has a chunk hanging loose. Kwik fit say it's not a problem (and so my insurance won't pay for it) and I think they're probably right. I don't like it hanging there though. Can I glue it back or there some sort of contraindication to adhesive and rubber?

It's just the rim protector, just cut the rubber tag off.

Tyre insurance? Could be worth trying another quick fit in that case.

Just stick it down with superglue and forget it!

I have had similar for two years. Tyres are now due for replacement now, so for 2/3rds of its life it has been like that. I tried to stick it, but the flexing of the tyre would not keep it in place. So for me, there has not been an issue.

As long as no cords showing it should be ok but keep an eye on it for next few weeks just to make sure it does turn into a bulge.
Bulges happen after side impacts where the internal cords have been damaged and start to snap.
Try q bond works for most things

I had something similar on a performance car, stuck it down with some loctite super glue it was okay till I changed the tyres 2 years later.

This, Superglue and rubber are a (permanent) match made in heaven.

So many variables to consider. What tyre, size how old, what car, speed loads?

The problem with gluing it, and even relying on Kwik fit is it wont be them at the wheel if it does give a problem in a years time. And you may well have forgotten about it.
How much is a new tyre? I'd be inclined to weigh that cost up against the world of st that may be thrown up if it gives you and issue and an accident or knackered wheel later on? Unlikely event, maybe, but it does sadly happen and more often than just the ones making the news.

If it were my car, i would change it. Or fit the spare and glue that up for emergency use only at least.

Alternatively, take it to an MOT station and ask their opinion as it is, would it pass. If not, that may be all you need to know.

I reckon I did the damage about two months ago but didn't notice it until a couple of days ago. So bulging probably not an issue. That said, I've got some seriously uneven wear and mismatched make on my four tyres
- fronts 5mm continental / 4.5mm continental
- rears 5.5mm (damaged tyre) dunlop / 2.5mm continental

I've only had the car (Audi A7 quattro) ten months so I don't know it's tyre history. I'm guessing there were a pair of tyres wearing quickly so one was replaced but with a dunlop?

So my thoughts are to leave the damaged tyre (albeit superglue the hanging off bit) and replace the 2.5mm with another dunlop?
None of which is covered under the insurance. Which is a shame because 275 / 30 ZR 21are nearly £300 a corner fitted!
I know they say quattro systems need matching tyres but I can't see the logic - the fronts are steering as well as pulling so there's a difference right there?
