Audi Q3: Acceptable Tread Depth Variance
Model with Longitudinally Installed Engine
Tread variance for models with a longitudinally installed engine, such as A4, A5, A6, A7, A8, Q5, Q7, ...
The variance between the front and rear axle in this case may not be more then 2 mm
Note
The technical background of the limitations are thermal pressure for the transmission oil due to a large difference in the rolling circumference of the tires.
- For all four wheels use only tires of the same construction type and tread.
- Always use tires with the deepest tread depth on the front axle.
- It is possible to change tires individually. However, Audi recommends changing tires on both sides.
- With sport differential on the rear axle, Audi recommends always replacing the tires on both sides of the rear axle.
Models with Transverse Installed Engine
Note
- Tread depth variance for models with crossways installed engine, such as A3, TT, Q3, A1, ...
- The variance between the front and rear axle in this case may not be more then 3 mm
