Audi Q3: Wheels and Tires
General information
The combination of a rim and tire
will be referred to as a wheel in
this Owner's Manual. If only one
of the components is referred to,
then the term tire or rim will be
used.
- Check your tires regularly for
damage, such as punctures,
cuts, cracks, and bulges. Remove
foreign objects from the tire
tread.
- If driving over curbs or similar
obstacles, drive slowly and approach
the curb at an angle.
- Have faulty tires or rims replaced
immediately.
- Protect your tires from oil,
grease, and fuel.
- Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
- Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
