Groove
means the space between two adjacent tread
ribs.
Load rating (code)
means the maximum load that a tire is rated
to carry for a given inflation pressure. You
may not find this information on all tires be­
cause it is no t req uired by law.
Maximum load rating
means the load rating for a t ire at the max i­
mum permissible inflation pressure for that
tire.
Maximum loaded vehicle weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight, and
(d) Production options weight
Maximum (permissible) inflation pressure
means the maximum cold inflation pressure
to which a tire may be inflated. Also called "maximum inflation pressure."
Normal occupant weight

Tires and wheels 249
Production options weight
means the combined weight of those installed
regular production options we ighing over 5
lbs. (2.3 kg) in excess of those standard items
which they replace, not previously considered
in curb weight or accessory weight, including

heavy duty battery, and spec ial tr im .
Radial ply tire
means a pneumatic tire in which the ply cords
that extend to the beads are laid at substan­
tia lly 90 degrees to the center line of the
tread .
Recommended inflation pressure
see ¢ page 248, Cold tire inflation pressure.
Reinforced tire
means a t ire design to operate at higher loads
and at h igher inflation pressures than the cor­
re sp onding standard tire. Reinforced tires
may be identified as "XL", "xl", "EXTRA LOAD",
or "RF" on the sidewa ll.
Rim
means a metal support for a tire or a t ire and
tube assembly upon which the tire beads are
seated.
Rim diameter

The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker label located on the
driver's side B-pillar. The tire pressure label on
your Audi lists the maximum combined
weight of all of the occupants and luggage or
other cargo that the vehicle can carry. For the location of the tire pressure label¢
fig. 205 .
.8, WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­ crease the risk of a loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
trol and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating .
.8, WARNING
-Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­
dent .
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.

Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­
lar.
The recommended tire pressures are on the
tire pressure label and in the table
¢ page 251, Cold tire inflation pressure.This
means that the pressure must be checked and
adjusted when the tire has not been driven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal friction as it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "cold ."
It is the inflation pressure in a "cold" tire that
counts. Therefore, you should never let air out
of a warm tire to match "Cold tire inflation
pressure" recommendations¢
page 251 . The
tires would then be underinflated and could
fail suddenly .
The tire pressure label on your Audi lists the recommended cold tire inflation pressures at
maximum capacity for the new, original
equipment tires that were on your vehicle at
the time it was manufactured. For the loca­
tion of the label¢
page 251, fig. 205 .
Most tires lose air naturally over time . They
can also lose some air if you drive over a pot­
hole or hit a curb while parking.
It is usually
not possible to see whether the radial tires
used today are underinflated just by looking
at them.
Therefore, be sure to check tire pressures at
least once a month and always before going
on a long trip. Make sure to take the number
of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See¢
page 255, Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres­
sures. Check all of the tires and be sure not to ..,. •

256 Tires and wheels
-Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly , including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX
KG OR XXX LBS" on your ve­
hicle's placard (tire inflation
pressure label)
¢ page 251,
fig. 205.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and pas­
sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 251, fig. 205.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150
lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is 650 lbs. (1400-7 SO
(5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual ..,

-All four wheels must be fitted with radial
tires of the same type, size (rolling cir­
cumference) and the same tread pattern .
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
derinflated .
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat,
increasing stopping distances and caus­
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them at the factory. The vehicle must have a
chassis designed for run flat tires. Incor­
rect use of run flat tires can lead to vehi­
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
with run flat tires. If run flat tires are
used, they must be installed on all four
wheels . Mixing tire types is not permit­
ted.
Tires and wheels 261
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 258,
fig. 209.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100. •
