Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized repair facility
check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 inch (1.6 mm) high and are
spaced evenly around the tire per­
pendicular to the running direc­
tion
c:> fig. 170. The letters "TWI"
or triangles on the tire sidewall
indicate the location of the tread­
wear indicators.
;;; l) Obey any applicable regulations in your "?
~ country . .....
Wheels
The tires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
c:> .&. .
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly . To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice ver­
sa. This will allow the tires to
have approximately the same
length of service life.
For unidirectional tires, make sure
the tires are installed according to
the running direction indicated on
the tire sidewall
c:> page 223.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hid­
den. Unusual vibrations in the ve­
hicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi

Tire repair set
General and safety pointers
Tire repair is intended only for temporary, short­
term use .
Fig . 1 75 Tire damage for which the Tire Mobility System is
not su ited
Your vehicle is equipped with a tire repa ir kit, the
Tire Mobility System (TMS) .
In the event of a tire fail ure, the TMS is in the
l uggage compartment under the floor. It consists
of the t ire sealant and an electric air pump.
Using
TMS , tire damage caused by foreign bodies
u p to abo ut
0.16 inch (4 mm ) in diameter can be
sealed reliably .
The foreign object must stay in the tire.
The tire sealant must not be used:
- for cu ts or pu nctures in the tire w hich a re larger
than 0 .16 inch (4 mm)
r=;,fig.175 @
-for d amage to the rim @
- if yo u h ave been drivi ng with very low t ire pres-
sures o r ti res wit h no air @
Using the
TMS is descr ibed in the section
¢page 217.

Taking the wheel off/installing a wheel
Follo w these instructions step-by-step for chang­
ing the wheel.
Fig. 181 Changing a wheel: using the screwdrive r handle
(with the blade removed) to turn the bolts
Fig. 182 Changing a wheel: alignment pin insid e the top
hole
After you have loosened all wheel bolts and
raised the vehicle off the ground, remove and re­
place the wheel as follows:
Removing the wheel
.. Remove the topmost wheel bolt completely
with the
hexagonal socket in the screwdriver
handle (vehicle tool kit)
¢fig . 181 and set it
aside on a
clean surface.
.. Screw the threaded end of the
alignment pin
from the tool kit hand-tight into the empty bolt
hole
¢fig. 182 .
.. Then remove the other wheel bolts as described
above .
.. Take off the wheel leaving the alignment pin in
the bolt hole
c::;, (D.
222
Putting on the other wheel
.. Push the wheel over the alignment pin .
.. Screw on the wheel bolts and tighten them
slightly using the hexagonal socket .
.. Remove the alignment pin and insert and tight­
en the remaining wheel bolt slightly like the
rest .
.. Turn the jack hand le counter-clockwise to lower
the vehicle until the jack is fully released .
.. Use the wheel bolt wrench to tighten all wheel
bolts firmly
c::;, page 220. Tighten them in a
crisscross pattern,
from one bolt to the (ap­
proximately) opposite one, to keep the wheel
centered .
.. Perform the steps required after changing the
wheel
c::;, page 219, A~er changing a wheel.
The hexagonal socket makes it easier to remove
the wheel bolts from the rim. Care should be tak­
en when removing the reversible blade.
(D Note
When removing or installing the wheel, the
rim could hit the brake rotor/ceramic brake
rotor* and damage the rotor. Work carefully
and have a second person to help you.
(D Tips
- When mounting tires with unidirectional
tread design
make sure the tread pattern is
pointed the right way
c::;, page 223.
- 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 dirt from these surfaces be­
fore remounting the wheel.
- Do not use the hexagonal socket in the
screwdriver handle to loosen or tighten the
wheel bolts .
