Tires with unidirectional tread 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 tire w ith a t read pattern in­
tended for use in a specif ic direction, please note
the following:
- The direction of rotation is marked by an
arrow
on the side of the tire.
- If the spare tire has to be inst alled in the inco r­
rect direction, use the spare tire on ly tempora ­
r il y since the tire will not be a ble to ac hieve its
optimum performance characterist ics with re­
gard to aquaplan ing, no ise and wear.
- We recommend that you pay part icu lar atten­
tion to th is fact d uring wet weather and that
you adjust your speed to matc h road condi­
tions .
- Rep lace the flat tire w ith a new one and have it
installed o n your veh icle as soon as possib le to
restore the hand ling advan tages of a un id irec­
t ional tire.
Notes on wheel changing
Please re ad th e inf ormati on ¢ page 224, New
t ires or w heels
if yo u are going to use a sp are tire
which is d iffe rent from the t ires on your ve hicle.
Af ter yo u cha nge a tire :
-Check the tire pressure on the spare immedi­
ately after installation .
- Have the wheel bolt t ightening torque
checked with a torque wrench as soon as pos­
sible by your authorized Audi dealer or quali­
fied workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 90
ft lb s. (120 Nm). ..,_

..... N
0 ::..:: co ,...., -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.
- 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
c> page 224, New tires or
wheels.
-
- 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 sudden maneuver they
could fly forward, injuring anyone in the ve­
hicle.
