I've seen lots of cars with the tyre worn on the edge like this , the alloy of the up right is still covered in muck so it's not rubbed ..but the lower arms have play in the bushes.
This will cause the steering angle to go out when cornering ..
shredded tyres - the last straw!

Thats you're problem, you probably had a slow puncture and the tyre deformed and destroyed itself on the knobbly bit you will never know for sure. This would happen to any tyre not just the Vreds. I'm running Vreds, my tpms is turned off with VCDS and my knobbly bit has been removed i check my tyre pressures regularly so hopfully i'll be ok but you never know.SuicideAl wrote:Lol. Good job the tyre pressure sensors on the 6 are as reliable as the rest of the car then!! Took mine off and threw them in the boot 2 years ago.
Sorry Chunky but I beg to differ. Are there any other premium cars out there which at the very least can take their respective recommended tyre size from ANY of the main/popular tyre brands without the rubber being fouled by the suspension? Let's leave aside those cars that clearly state that there is a very specific tyre that was designed for their car.
Admittedly I don't know the answer to my own question and we appear to be uninformed as to exactly WHY this occurs.
To be blunt IMO I'd be bold enough to suggest Audi failed in NOT factoring in enough clearance. Hardly rocket science is it? Rubber, metal, and gases all expand, contract, and loosen with age and are affected under various conditions whether heat or load related. I'm going to make sure my TPM sensors are fully functional when I next get her rebooted. Wont be a cure methinks but it will help peace of mind at least.

I check mine every few weeks, there is no sign of any wear at the mine. I do also constantly check my tyre pressure are correct and my TPMS works

. Maybe RS5 or S5 Hatchback to come...My last set of tyres shredded on 'ol knobbly' so i took the angle grinder to it before buying a new set of conti 5P.Has been perfect since but i do have play in the top rear ball joints which may have an afect of whether it rubs or not so i will get that addressed just to be safe

I think we need to add more weight to grizz's comment. It's not always the knobbly bit causing excessive inside wear. We should be careful to mention the worn bushes as well as the knobbly bit when a problem like this crops up.

Totally agree - some of these cars are nigh-on ten years old!Shoppinit wrote:I think we need to add more weight to grizz's comment. It's not always the knobbly bit causing excessive inside wear.

The wheel is bolted to the hub, through the bearing into the upright. The upright (knobbley) is only going to move with relation to the tyre if the bearing has play in it?

If there is too much toe or camber, the tyres will scrub, no matter how good the tyres or bearings are.
If the suspension bushes are worn then the whole hub carrier can find itself in the wrong position causing excess wear to the inside edge of the tyre under cornering. In this case the tyre remains in the correct position with respect to the hub carrier and knobbly bit.bam_bam wrote:^^ So by that ratioale, either the bearing had play, the "knobby bit" is at fault or the tyre sidewall just wasn't up to the task, ne?
Not saying it's not the knobbly bit, but it could be explained by other things. Including impact damage which caused a hernia which then rubbed on the knobbly bit.
It's the "6 inches" that gives pause - if they tyre was rubbing on the suspension you would expect damage all around the circumference.

Indeed, I missed the 6in bit inthe 1st post. Either the tyre had a defect, or something else happened.Shoppinit wrote: It's the "6 inches" that gives pause - if they tyre was rubbing on the suspension you would expect damage all around the circumference.
It is very easy to cut off big pieces of the sidewall whilst kerbing the wheel (ask me, or more precisely SWMBO) so I imagine it can happen on the inside of the tyre too.
