262 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 origina l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
¢
fig . 212 running across the tread. Depend­
ing on the make, there will be six to eight of
them evenly placed 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 tires must be replaced .
Different figures may apply in other countries
¢ & .
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
¢ page 258.
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
Ma intenance and Warranty 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¢
fig. 213.
-Extra care must be taken when rotating di-
rection-specific tires¢
page 279.
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal­
anced, resulting in vibrations you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive 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 exces ­
sive tire wear, impairing the safety of the vehi­
cle. If tires show excessive wear, have the
whee l alignment checked by an authorized
Audi dealer or qualif ied workshop.
All wheel drive
Vehicles with quattro ® must a lways have tires
of the same size, construction and tread type.

wheels on your vehicle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly .
Tire pressure indicator appears
Appl ies to vehicles: w ith t ire pressure monitoring sys te m
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig . 2 15 Display: underin flati on wa rning
Fig. 216 Disp lay: System malfunction
Using the ABS sensors, the tire pressure moni­
tor ing system compares the t ire tread circum ­
fe rence and vibration characteristics of the in­
d iv idual tires.
If t he pressure decreases in one
or mo re tires, th is is indica ted in the instru­
men t clus ter with a
[I] warning symbo l and a
message ¢
fig. 215. The driver message in the
disp lay goes out after 5 seconds . The drive r
message can be d isplayed again by pressing
the
! SET ! button. If only one tire is affected,
the display will indicate its pos ition.
The tire press ure monitoring system must be
reset via radio o r MM! * each time the p res­
sures are adjusted (e.g . when sw itching be­
tween partial and full load pressure) or after
changing or replacing a t ire on your vehicle
<::> page 2 72 . You can find the recommended

drive r's side B-pillar
c!;> page 256 .
Tire tread circumference and vibrat ion charac­
teris tics can change and cause a tire pressure
warning if:
- t he t ire p ress ure in one or mo re tires is too
low,
- t he tir e has s tructural damage,
- the t ire pressu re was changed, w heels rotat-
ed or rep laced but the TPMS was not reset

Check the tire or tires and replace or repa ir if
necessary . T he

ment cluster also illum inates

Check/cor rect the p ress ures of all fou r tir es
and reset TPMS via radio o r M MI*.

Ifll@lf:1 appears after switching the ignition
on or while driving
c::> fig . 216 and the [I] indi­
cator light in the instr ument cluster blinks for
approximately one m inute and then stays on,
there is a system malfunction. See your au­
thorized Aud i de aler as soon as possible .
& WARNING ~
- If the tire pressure ind icator appears in
the instrument cluster display, one or more of your tires is significant ly unde r­
inflated. Reduce your speed immediately
and avoid any hard steering or b raking
maneuvers. Stop as soon as possib le and
check the tires and their pressures . In­
flate the tire pressure to the prope r pres­
sure as indica ted o n the v ehicl e's tire
p ressu re labe l
c::>page 256. Driving on a
sig nifican tly un der- infla te d tire causes
the t ire to ove rheat and can lead to ti re
fa ilu re . Unde r-inflation also is l ikely to
impair the vehicle's hand ling and stop­
ping ability .
