Bad things happened!
Hope you are ok and not going too quick when it happened!?
No idea in the cause I'm afraid. Are you able to get some clearer daytime shots?

Thanks folks. All safely home after a few hours. Car is only 3 months old with standard tyres. You might notice that the metal rim around the brake disc is bent over to a sharpened edge which has worn away and sliced the inside of the tyre. Has anyone seen this happen before? Struggling to understand how that disc could have folded over like that.

My only suggestion is a large twig/stone got lodged in there and acted as a lever to put it out... Not seen anything like this before.

Thankfully the tyre did not blow. The consequences could have been far worse. The brake disk guard is there to protect the disk. I do not believe that is the cause of your problem. It does not extend out as far as the damage on your tyre. I suggest you look for something else which may have been rubbing on the tyre.

I guess you will be replacing that tyre today? You might want to visit a reputable tyre specialist and ask them to advise re cause of the tyre failure.

Barley53,
Missile is correct. The disc guard is the same diameter as the disc plus caliper give or take a few mm and is well within the wheel so could not damage the tyre. It is deformed however in your photo so may have been damaged by road detritus but one would normally be aware of a substantial level of noise if a foreign body got stuck in it and rubbed against anything as the wheel rotated. Do you recall driving over anything or clipping a kerb at speed? Seems odd that it has gone on the inside, is the outer sidewall damage free?

Must admit, in the cold light of day I realised that the warped disc couldn't have caused the tyre damage. The outer side is untouched. I've not hit anything to speak of. Since I've had the car it's always made a bit of a strange whine when going over 40mph and when in reverse, I could never identify anything specific, not sure now. Currently with vindis huntingdon, they've always looked after me, and are investigating possible causes. bill coming my way I suspect...thanks again everyone

That type of failure normally is associated with a remould (the tread lifting off) I'm sure you wouldn't fit remoulds. How old is the tyre? and how many miles as it covered? The bent plate I would think was due to the tyre tread lifting.

Bonzoboy, i've had the car since new for nearly four months. Done around 4.5k miles, the majority on A roads and motorways. Hope you'll forgive my ignorance, but what does "tyre tread lifting" mean? That the tread literally parts from the tyre?

Yes, I'm sure that you will have seen the remnants of truck tyre treads lying on the hard shoulder. Similar things happened in the early part of the 2013 season of F1 although the Pirellis were certainly not remoulds.
One would not expect a Goodyear to fail in such a way without provocation and it raises the question as to whether it was just a faulty tyre. It may be worth having a good look at the other 3 to check that their inner sidewalls are showing no signs of failing.

Ah yes, thanks cruicd. A bit concerned at audi's reaction when they got round to looking at the car yesterday. They've tried to put a new tyre on (and charge me for it). I've had to reiterate that because I don't know what caused the tyre damage, rather than put the spare on I called the RAC and had the car lifted. I'd already sent the photos. I appreciate that they need to move her but at this stage imo if they put a tyre on it's at their risk. Audi will now be investigating further next week.

Please tell me you fitted the spare and did not drive the car to Audi dealer with that tyre on? Very few (if any?) Audi dealers fit tyres. They sub contract to a tyre fitter and charge you extra.

No chance Missile, as previously mentioned I got a flatbed from the RAC. I was halfway changing changing to the space saver when I noticed that bent guard...

Audi got back to me today, the techie reckons a screw caused all the damage to the inside of the tyre and the bending of the metal shield as seen in the pics. I'd appreciate any thoughts anyone might have on this.
