Tyre depths left to right and front to back

Hi there,
I got a puncture this morning, and it was caused by Audi at a service yesterday. The tread on the fronts were 4mm and on the rear 4mm. They are putting a new tyre on on Monday which will have a depth of 7mm. Is this ok? There will be a 3mm difference left to right at the front? Will this affect anything? I though I'd read/hears somewhere that all tyres should be about the same becasue of the Quattro system.
Cheers

I can't see how front to back makes that much difference. Very slight rotational sizes. But left to right doesn't seem great, I'd be looking for Audi to be replacing both left and right front to keep them the same.

They won't, they went into their manual etc. and said it was fine. Average of front two against average of back two, so 5.5mm average on the front now against 5mm on the back two they say is fine, the limit it 2mm apparently....unless anybody can tell me different? I have just got them to order another and fit two new fronts, one ill pay for and one they are, i'll keep the 4mm front left good one as a spare inc ase it happens again!

That's a bummer! Sorry mate. I'd want them to at least fit it free though!

Summary. Need to be within 3% of rolling diameter. I.e you could have 7mm on one and 1.5 on the other if you really want - but i wouldnt advise it...

Thanks a lot for the info, I'm still getting the other front replaced to for peace of mind!
How many miles are you guys getting out of a set? Mine is on the Bridestones it came with....

The general consensus appears to be that michellin pilot super sports are the best all rounder. Miles wise totally depends on your driving style really. At least 10k for me, but then my wife uses my car as a daily
