wear on steering, suspension and tires. A wheel must also be
rebalanced when a new tire is
installed.
Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, im
pairing the safety of the vehi
cle. If tires show excessive
wear, have the wheel alignment checked by an authorized Audi
dealer or qualified workshop.
All wheel drive
Vehicles with quattro must al
ways have tires of the same
size, construction and tread
type. For details see
¢page 176.
A WARNING
Sudden tire failure can lead
to loss of control, a crash and serious personal injury!
-Never drive a vehicle when the tread on any tire is worn down to the wear indica
tors.
-Worn tires are a safety haz
ard, they do not grip well on
wet roads and increase your risk of "hydroplaning" and
loss of control.
Tires and wheels 229
-Always keep chemicals that can cause tire damage, such
as grease, oil, gasoline and
brake fluid away from tires.
-Tires age even if they are not being used and can fail
suddenly, especially at high speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and
at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous histo
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.

(D Note
Do not lift the vehicle by the sill. Position
the vehicle jack only at the designated lift
ing points on the sill. Otherwise, your vehi

Taking the wheel off/installing a wheel
Follow these instructions step-by-step for
changing the wheel.
Fig. 195 Changing a wheel: using the screwdrive r han·
dle (with t he bl ade removed) to turn the bolts
Fig. 196 Changing a wheel: a lignment pin insid e t he
to p hole
After you have loosened all wheel bolts and
raised the veh icle off the ground, remove and
replace the wheel as follows:
Removing the wheel
.,. Remove the topmost wheel bolt completely
with the
he xa gonal socket in the screwdriv
er handle (vehicle tool kit)
c> fig. 195 and
set it as ide on a
clean surface.
.,. Screw the threaded end of the
alignment
pin
from the tool kit hand-tig ht into the
empty bolt hole
<='>fig. 196.
.,. Then remove the other wheel bolts as de
scribed above. .,.
Take off the wheel leaving the a lignment pin
in the bo lt hole
c::> (D .
Putting on the other wheel
.,. Push the whee l over the alignment pin.
.,. Screw on the wheel bolts and tighten them
slightly using the hexagonal socket .
.,. Remove the alignment pin and insert and
tighten the rema ining wheel bolt slightly
like the rest.

them
in a crisscross pattern, from one bolt
to the (approximately) opposite one, to keep
the wheel centered .
.,._ Perform the steps required after changing
the wheel
c::> page 245, After changing a
wheel.
The hexagonal socket makes it easier to re
move the wheel bolts from the rim. Care
shou ld be taken when removing the reversible
blade.
(D Note
When removing or installing the wheel,
the rim cou ld hit the brake rotor/ceramic
brake rotor* and damage the rotor. Work
carefully and have a second person to help
you.
@ Tips
- When mounting tires w ith unidirectional
tread design
make sure the tread pat
tern is po inted the right way
c::> page 249.
-The wheel bolts should be clean and easy
to turn. Check for dirt and corrosion on
the mating surfaces of both the wheel
and the hub. Remove all d irt from these
surfaces before remounting the wheel.
- Do not use the hexagonal socket in the
sc rewdriver handle to loosen or tighten
the whee l bolts.
