Replacing tyres on an Audi Quattro? Diff winding???
Discussion
Can someone please clarify the situation regarding the tyres on a Quattro. I've looked on the internet and Audi forums but the info seems a bit vague and contradictory wherever you look.
Advice seems to be that you must either replace all 4 or at least 2 on the same axle to prevent the diff getting 'wound up'.....all a bit new to me!
I recently replaced my rear tyres as they were shot and today I got a nail in one of my fronts, and it can't be repaired. Damn annoying as the rears cost me a small fortune.
Both my fronts are quite worn with only a couple of mm left on 'em.
Do I have to replace BOTH fronts? I have a tyre sitting in my shed at the mo with 5-6 mm left on it?
Would I be able to fit this with the opposite side continuing with low tread? Could I fit the one with 5-6mm with a brand new one on the opposite side? Best to replace both?
Alas I'm not made of money and the tyres are gonna set me back a minimum of £177 each which is a bit painful at this time of year

The manual states..
On vehicles with 4 wheel drive, all 4 wheels must always be fitted with tyres of the same type, make and tread pattern, so that the drive system is not damaged as a result of constant differences in the wheel speeds.
Then it states
The use of tyres with varying degrees of wear will not adversely affect the four wheel drive transmission.
Kinda confuses me does that as it seems that putting brand new Good Years on the back and brand new Conti's on the front is a no-no but having the same brand with 6mm on the rear and 2mm on the front is OK

It's never a good idea to have different tyres on the same axle. You can have different ones on the front and on the back, although this might have an undesired effect on handling. The centre diff will be fine. I would just get a couple of tyres and put the 5-6mm one on the spare wheel.

The first bit seems overly cautious given how many thousands of Audis are out there with mis-matched tyres on. I can't see how odd-tyres would effect a four wheel drive car but not a two wheel drive car, especially as tyres with different amounts of wear are ok.The manual states..

Presuming this is an a4 upwards its fitted with a torsen centre diff.
These are pretty much bullet proof.
I have owned many of these and mostly I use a full set of matched tyres, however.... I ran my 1989 coupe quattro on 4 different tyres for about a year , all with varying degrees of wear. Result - No problem what so ever.
I would imagin if you blew the centre diff in warranty and you turned up with mismatched tyres then they would perhaps not look kindly on this, the reality is it should be fine with whatever you want to do as long as the tyres are all the same size.
