Tyres on 2.7 Quattro A6

[Raven Flyer]

I got a puncture at the weekend and wrecked a tyre limping home (less than a ****** mile).

Can I just replace one tyre? If not is it 2 or 4 that need to be changed? Can I use different brands front to rear?

Bad news is that it is recommended that all 4 tyres are changed at the same time, with same brand, etc on all wheels so as not to b*gger the quattro system.

Might get away with it if the three remaining tyres are new.

[Seez]

Depends how the others are worn, if they are getting close then change them all, if not get two the same, so the car still has the same brand all the way around. Might be an opportune time to swap them around as well to have the newer ones on the front.

All tyres have approx 5mm, the spare which is on at the moment, is new with 8mm.

I spoke to Audi Customer Services about this. If Audi sell a used car, worn tyres are replaced in singles on the fwd cars and in pairs accross the axle on Quattros - they definitely don't replace all 4.

When I had a Boxster, Porsche advised replacing tyres in pairs regardless of drive.

[Seez]

Yes replacing four's is silly, do pairs at worse, unless they are all shot of course!

In your case, get the spare put on and a new one, keep the 5mm for the spare.

I had an email from Audi Customer Services on this point. They said that all four wheels must have the same make, size, tread pattern and compound of tyre and that tread depth variation should be no more than 3mm across all 4 wheels.

I bought 4 no Vredestein Ultrac Sessantas for mine, and couldn't be happier in terms of grip, handling and noise. Plus they were half the price of Dunlops! (check tyre revire websites)

I was told that as long as front-back are within 3mm, and side-side within 1mm, you'll be fine. (Audi main dealer)

[Seez]

Sounds like good advice, I change the tyres on mine anyway when they get below 3mm. Running Michelin Pilot Sport 2 all round currently and they are very good tyres, but not cheap...

I meant 3mm front to back. i.e. if the fronts are 5mm, then the backs should be between 2 & 8mm.

That's how I used to run my 996 C4. I had 18s on that and used to run different compound Pirellis from front to rear, sometimes different makes front to rear too. I never had a problem and Porsche also use a Torsen centre diff.

Same make, same compound, same tread would be a nightmare.

Which end tyres tend to wear out first on A6 Quattros?

Mines an A4 Cab Quattro, and they're pretty even wear I'd say. I do mine is pairs simply 'cos I had a puncture on a part-worn front, so replaced the pair, so now they're out of sync with the backs.

Fronts wear slightly faster, but not by much in my experience.

Tyre manufacturers always recommend to put new tyres on the rear, regardless of which wheels are driven.

I agree, there is very very little in it. I change all 4 together
