Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto-
matic transmission, power steer-
ing, power brakes, power win-
dows, power seats, radio, and
heater, to the extent that these
items are available as factory-in-
stalled equipment (whether in-
stalled or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent.
Numbers of 55 or lower indicate a
low sidewall for improved steer-
ing response and better overall
handling on dry pavement.
Bead
means the part of the tire that is
made of steel wires, wrapped or
reinforced by ply cords and that is
shaped to fit the rim.
Bead separation
means a breakdown of the bond
between components in the bead.
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the tire pressure recom-
mended by the vehicle manufac-
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo-
meters) at low speeds in the three
hour period before the tire pres-
sure is measured or adjusted.
Curb weight
means the weight of a motor ve-
hicle with standard equipment in-
cluding the maximum capacity of
fuel, oil, and coolant, air condi-
tioning and additional weight of
optional equipment.
Extra load tire
means a tire designed to operate
at higher loads and at higher in-
flation pressures than the corre-
sponding standard tire. Extra load
tires may be identified as “XL”,
“xL’, “EXTRA LOAD”, or “RF” on
the sidewall.

maximum specified pressure > A.
Checking and correcting tire
pressure
>Check the tire pressure at least
once per month and also check it
before every long drive.
> Always check the tire pressure
when the tires are cold. Do not
reduce the pressure if it increas-
es when the tires are warm.
>Refer to the sticker > fig. 176
for the correct tire pressure.
> Correct the tire pressure if nec-
essary.
> Save the changed tire pressure
> page 253.
> Check the pressure in the spare
tire (compact spare tire)*. Al-
ways maintain the maximum
temperature that is specified for
the tire.

and follow the important safe-
ty precautions in > page 247.
—The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con-
trol.
—Incorrect tire pressure increas-
es tire wear and has a negative
effect on driving and braking
behavior, which increases the
risk of an accident.



Z\ WARNING
Always adapt the tire pressure
to your driving style and the ve-
hicle load.
—Overloading can lead to loss of
vehicle control and increase

@) Note
Replace lost valve caps to re-
duce the risk of damage to the
tire valves.
(*) For the sake of the envi-
ronment
Tire pressure that is too low in-
creases fuel consumption.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al-
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.

ing positions: two people in the front, one person in the rear
Your safety and that of your pas-
sengers also depends on making
sure that load limits are not ex-
ceeded. Vehicle load includes ev-
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi-
cle’s Gross Vehicle Weight Rating
(“GVWR”).
The “GVWR” includes the weight
of the basic vehicle, all factory in-
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi-
mum load includes the number of
passengers that the vehicle is in-
tended to carry (“seating capaci-
ty”) with an assumed weight of
150 lbs. (68 kg) for each

Wheels


ZA WARNING
Wheel bolts that are tightened or repaired in-
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi-
cation, see > page 265, Finishing.
— Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
— Only use wheel bolts that fit the rim.
— Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be-
cause of their construction (width, compound,
tread pattern), summer tires provide less traction
on ice and snow.

>» Use winter tires on all four wheels.
> Only use winter tires that are approved for your
vehicle.
> Please note that the maximum permitted
speed may be lower with winter tires > A\ in
General information on page 234. An author-
ized Audi dealer or authorized Audi Service Fa-
cility can inform you about the maximum per-
mitted speed for your tires.
> Check the tire pressure after installing wheels
> page 244.
The effectiveness of winter tires is reduced great-
ly when the tread is worn down to a depth of
0.16 in (4 mm). The characteristics of winter tires
also decrease greatly as the tire ages, regardless
of the remaining tread.
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear, and fuel
consumption.
250
G) Tips
You can also use all season tires instead of
winter tires. Please note that in some coun-
tries where winter tires are required, only win-
ter tires with the 44 symbol may be permit-
ted.
Snow chains improve both driving and braking in
winter road conditions.
> Only install snow chains on the front wheels.
> Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol-
low the instructions from the manufacturer.
> Note the maximum speed of 30 mph
(50 km/h). Observe the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author-
ized Audi Service Facility to see if you may use
snow chains.
Use fine-mesh snow chains. They must not add
more than 0.53 in (13.5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with-
out snow. Otherwise, you could impair driving
ability and damage the tires.

ZX WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci-
dent.
C) Note
Snow chains can damage the rims and wheel
covers* if the chains come into direct contact
with them. Remove the wheel covers* first.
Use coated snow chains.
G) Tips
When using snow chains, it may be advisable
to limit the ESC > page 118.

ZA WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.

A WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat-
ed.

Tire pressure monitoring
system
(1) General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire
inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS)
that illuminates a low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving ona signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
252
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.

dicator

g indicator
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Using the ABS sensors, the tire pressure monitor-
ing system compares the tire tread circumference
and vibration characteristics of the individual
tires. If the pressure changes in one or more
tires, this is indicated in the instrument cluster
display with an indicator light @ and a message.
If only one tire is affected, the location of that
tire will be indicated.
The tire pressures must be stored again each
time you change the pressures (switching be-
tween partial and full load pressure) or after
changing or replacing a tire on your vehicle
=> page 253. The tire pressure monitoring system
only monitors the tire pressure you have stored.
Refer to the tire pressure label for the recom-
mended tire pressure for your vehicle
=> page 244, fig. 176.
