'"" .... 0 0 :c ' Tires with unidirectional tr ead design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the
right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare t ire with a tread pattern in­
tended fo r use in a specific direction, please note
the following:
- The direction of rotat ion is marked by an arrow
on the side of the tire .
- If the spare tire has to be installed in the incor­
rect direction, use the spare tire only tempora ­
rily s ince the tire will not be able to achieve its
opt imum performance character istics with re­
gard to aquaplaning, noise and wear .
- We recommend that you pay particular atten­
t ion to this fact during wet weather and that
you adjust your speed to match road condi­
tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tiona l tire .
Notes on wheel changing
Please read the information ~ page 290 if you
are going to use a spare tire which is different
from the tires on your vehicle.
After you change a tire:
- Check the tire pressure on the spare immedi­
ately after installation.
- Have the wheel bolt tightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or a
qualified service station.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb
(120 Nm).
- If you notice that the wheel bolts are corroded
and difficult to turn while changing a tire ,
they should be replaced before you check the
tightening torque .
Emergency assistance
-Replace the flat tire with a new one and have
it installed on your vehicle as soon as possi­
ble. Remount the wheel cover.
Until then , drive with extra care and at reduced
speeds.
A WARNING
- If you are going to equip your vehicle with
tires or rims which differ from those which
were factory installed, then be sure to read the information
Q page 290.
- Always make sure the damaged wheel or
even a flat tire and the jack and tool kit are
properly secured in the luggage compart­
ment and are not loose in the passenger
compartment.
- In an accident or sudde n maneuver they
could fly forward, injuri ng anyone in the ve­
h icle .
- Always store damaged wheel, jack and tools
securely in the luggage compartment. Oth­
erwise, in an accident or sudden maneuver
they could fly forward, causing injury to pas­
sengers in the vehicle.

on the spare tire is not permitted. If it is
necessary to drive with tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear tire . The newly
