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 ther
Note
When measuring tread depth, take measurements in the main
grooves.
Do not measure on the TWI (tread wear indicator).
Tread depth of a tire must be measured in the main grooves
at the points showing the most wear. Main tread grooves can be
recognized by the TWI. The positions of t
