If you have to change on tire on a quattro do you have to change all of them due to differing tread depth?
It is usually recommended that you change both tires in the set (front or back) at the same time. This keeps the car level side to side and prevents uneven wear. A common practice with a full size spare is to match the spare with a new tire and use the odd tire off the wheels to replace the spare. This puts two new tires on the car and a serviceable one for a spare.
My opinion, based on my knowledge is: If you replace one tire with the exact same brand, model, and size tire, and the other tire on the same axle has less than half it's tread left then also replace it. That way you have two tires on that axle with the same diameter. If it has more than half it's tread left, then just replace the one tire. The difference in diameter is not significant enough to do any harm. You do not have to worry about the two tires on the other axle. If on the other hand you are replacing the tire with a different brand tire or different size tire, then absolutely replace both tires on that axle. Different tire brands have different diameters even if they are listed as the same size.
