    The S3 is predominantly a FWD car until it senses that there is too much power in the front wheels and begins to lose grip. The Haldex unit then kicks in and transfers a proportion of the power to the back wheels, making it 4WD. The S3 is not a permanent 4WD.

    That's the easiest/simplest way to explain it.

    Without seeing images of the tyre wear, I cannot comment on your alignment. However, if you have only replaced the front tyres recently, the rear ones will obviously reach their wear limit sooner. It would also be a good idea to let us know of your driving style as this may also affect your tyre wear.

    Also is it lowered? you may need adjustable tie arms to combat the camber..

    Is your car lowered? Sometimes when lowering the S3 it can cause negative camber... Which would cause wear on the inside iirc. There's no adjustment on the rears, unless you buy adjustable tie bars.

    In that case, camber will most likely be out causing uneven wear to the inside edge of the tyres.

    As stated above, you will need some adjustable rear tie bars to combat this, which will obviously need to be set up on an alignment system to bring back within tolerance. You may aswell go for a full 4 wheel alignment and make sure both front and rear are spot on.
