206 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 144 running across the tread. Depend­
i ng on the make, there will be six to eight of
them evenly p laced around the tire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different figures may apply in other countries
c::> & .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 202 .
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service interva ls outlined in your
Warranty
& Maintenance Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 145.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 22 7 .
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A whee l must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle. If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop.
all-wheel drive
Vehicles with quattro ® mus t always have tires
of the same size, construction and tread type .

224 What do I do now?
What should I be
aware of when
changing a tire?
General information
The following sections will provide you with
important information on how to change a
tire using the vehicle tool kit.
However, we recommend that you have a
qualified service center change the tire and
perform all work associated with changing it .
Wheels with cap-covered wheel bolts
Applies to vehicles: with cap-covered whee l bolts
The caps must be removed first from the
wheel bolts before the bolts can be un­
screwed .
Fig. 157 Wheel change: removing the wheel bolt caps
Removing
• Push the plastic clip provided with the on­
board tool kit down over the wheel bolt cap
u ntil it engages.
• Pull on the properly engaged
plastic clip to
extract the cap¢
fig. 157 .
Refitting
• Place the caps over the wheel bolts and
push them back in.
The caps are there to protect and keep the
wheel bolts clean.
Decorative wheel covers
Applies to vehicles: with decorative wheel covers
The decorative wheel covers must be removed
first to access the wheel bolts .
Fig. 158 Wheel change: removing the wheel cover
Removing
• Insert the hook prov ided with the on board
tool kit into the hole on the center hub
piece.
• Pull off the
decorative wheel cover
¢fig. 158.
Loosening and tightening the wheel
bolts
The wheel bolts must be loosened before rais­
ing the vehicle.
Fig. 159 Wheel change: loosening the wheel bolts
Loosening
• Fit the wheel bolt wrench over the wheel
bolt and push it down as far as it will go.
• Close your grip around the
end of the
wrench handle for maximum torque and
turn the wheel bolts
counter-clockwise
about one single turn in the direction of ar -
row
r:!> fig. 159. .,..

(D Note
When removing or installing the wheel,
the rim could hit the bra ke rotor and dam­
age the rotor . Wor k carefully and have a
second person help you.
N ever use the hexa gonal s ocket in the ha n­
d le of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversib le blade from the screw­
drive r before yo u use the hexagonal
socket in t he handle to t urn the whee l
bo lts .
- When mounting tires with
unid irectional
tread design
make s ure the tread pat­
te rn is poi nte d the r ight way
¢pag e 227.
-The wheel bolts should be clea n and easy
to tu rn . Ch eck for dirt and corros ion on
the mat ing su rfaces of both the whee l
a nd th e hu b. Remove a ll dir t fro m these
s ur fa ces before remo unting the wheel.
Notes on wheel change
Pl ease rea d the information ¢ page 207, New
tires and replacing tires and wheels,
i f you are
going to use a spare t ire which is different
from the tires on your ve hicle.
Afte r you change a tire:
- Check the tire pressure on the spare imme ­
diately after mounting .
- Have the wheel bolt tightening torque
che cked with a torque wrench as soon as
possible 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 while changing a tire that the
wheel bolt s are co rroded and diffi cult to
turn , then they should be replaced before
you check the t ightening torque.
What do I do now? 227
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover .
Until then , drive with extra care and at re­
duced speeds.
A WARNING
-
- If you are go ing to e quip your ve hicl e
wit h tires o r rims which differ from those
which were factory installed, t hen be
sure to read the information¢
page 207,
New tires and replacing tires and
wheels .
-Always sto re the tools secu rely in lug­
gage compartment. Othe rwise, in a n ac­
cident o r su dd en maneuv er they cou ld fly
forwa rd, causi ng injury to passe ngers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tr ead design must be
mounted with their tread pattern pointed the
right dire ction.
A u nidirectional tire can be identified by ar­
rows on the sidewall,
which point in the direc ­
tion of t he rota tion. Yo u m ust follow the
s p ecifie d direction of rot ation. This i s nece ssa ­
r y in order fo r these tires to develop t heir op­
timum character istics regard ing grip, road
no ise, wear, and hydrop la ning.

Maintenance booklet.
Under difficult operating conditions , for ex­
ample at extremely low outside temperatures ,
in very dusty regions, etc., some service work
shou ld be pe rformed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air fi lter.
