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
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.
