& WARNING (continu ed )
crashes and serious personal in jur ies . Have worn or da maged t ires
replaced immediately .
• Tires age even if they are not being u sed and can fail suddenly ,
especially at high speeds. T ires that are more than 6 years old can
only be used in an emergency and then w ith special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the co mbined we ig ht ( in excess o f those sta nda rd items
which may be rep laced) of automatic transmission, power steering,
power brakes, power w indows, powe r seats, rad io, a nd heater, to
the extent that these items are avai lab le as factory-installed equip­
m ent (w hether insta lled or not).
Aspect ratio
means t he ratio o f th e height to t he w idt h of the tire in perce nt.
N umbers of 55 or lower indicate a low sidewa ll for improved
steer ing respo nse and b ette r overall ha ndl ing on dry pave ment.
Bead
means the part of the tire that is made of stee l wires, wrapped or
reinforced by ply cords and that is shaped to fit the rim.
Bead separation
means a breakdow n of the bond be tween co mponents i n the bead.
Cord
means the strands fo rmi ng the plies in the ti re.
& W ARNING (continued )
• Never mount used tires on your vehicle if you are not sure of
their "previous history. " Old used t ire s may ha ve been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and lo ss of vehicle control.
• If you noti ce unusual vibration or if the vehicle pulls to one side
when driving , always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
mea ns t he ti re pressure reco mm ended by the ve hicle ma nufacturer
for a tire of a designated size that has not been d riven for more tha n
a cou ple o f miles (k ilometers) at low speeds in t he t hre e ho ur per iod
before the tire pressure is measured or ad justed .
Curb weight
means the weight of a moto r vehic le with standard equipment
i nc lud ing the max imu m capac ity o f fue l, o il, and coola nt, a ir c ond i­
tioning and additiona l weight of optional equipment.
Extra load tire
means a tire designed to ope rate at higher loads and at higher infla­
tion pressures than the corresponding standard tire. Extra load tires
my be identified as "XL",
"xi", "EX TRA LOAD", or "RF" on the side ­
wa ll.
Gross Axle Weight Rating ("GAWR ")
means the load -carrying capacity of a sing le ax le system, measured
at the ti re -ground interfaces.
Gross Vehicle Weight Rating ("GVWR "l
means the ma ximum tot al l oade d weigh t of the vehicle.

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
because it is not required by law.
Maximum load rating
means the load rating for a tire at the maximum permissible infla­
tion 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
in flated. Also called "maximum inflation pressure ."

Production options weight
means the combined weight of those installed regular production
options weighing 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 brakes, ride levelers, roof rack, heavy duty battery, and special trim.
Radial ply tire
means a pneumatic tire in which the ply cords that extend to the
beads are laid at substantially 90 degrees to the centerline of the
tread.
Recommended inflation pressure
see =:> page 235, "Cold tire inflation pressure".

tion pressures than the corresponding standard tire. Reinforced
tires my be identified as "XL", "xi", "EXTRA LOAD", or "RF" on the
sidewall.
Rim
means a metal support for a tire or a tire and tube assembly upon
which the tire beads are seated .

The correct tire pressure for the spare wheel is located on a label on
the driver's side B-pillar .
Because technica l changes may be made to vehicle equip ment
during the mode l year, always compare the tire size designat ion on
the tire pressure la bel on y our vehicle with the tires on your vehicle.
Make sure tha t the t ire size information on the veh icle labe l is the
same as the size of the tires on the vehicle. Th is is especially impor ­
t ant if the vehicle belongs to someone e lse or you boug ht the
vehic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers a lso depends
on making su re tha t load limits a re not exceeded . Vehi cle loa d
inc ludes everybody and everything in and on the vehicle. These load
limits are technically referred to as the vehicle's Gross Vehicle
Weight Rating ("GVW R"). The Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two
ax les. The Gross Vehicle We ight Rat ing and the Gross Ax le Weig ht
Rating are listed on the safety comp liance sticker labe l located on
t he driver's side B- pillar. The tir e pressure labe l on y our Audi lists
the maximum combined weight of a ll of the occupants and luggage

& WARNING
Overloading a vehi cle can cause loss of vehicle control , a crash or
other accident, serious personal injury, and even death .
• Carrying more weight th an your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control.
• 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 overloaded c an fail suddenly
causing loss of control and a crash .
& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
s erious o r fatal a ccident .

& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident , serious personal injury , and even death .
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
& WARNING (continued )
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation , causing loss of control
and a crash .•
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and
luggage or other things that you plan to
transport 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 OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS "on your vehicle 's placard (tire infla­
tion pressure label)~
page 238, fig. 148.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle. ..,

& W ARNING (continu ed )
• All four wheels must be fitted with radial tire s of the same type ,
s ize (rolling cir cumference ) and the same tread pattern . Driv ing
with different t ires redu ces vehicle h andling and can lead to a loss
of contro l.
• If the spare tire is not the same a s the tires that are mounted
on the vehicle -for e xample with winter tires -only use the spare
tire for a short period of time and dr ive with extra c are . Refit the
norm al road wheel as soon as safely possible .
• 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 t ires that are properly inflated and
not over or underinflated .
• For te chnical 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 vehicle wheels , make sure
that the air flow to the brakes is not blo cked . Redu ced airflow to
the brakes can them to overheat , in creasing stopp ing distances
and causing a collision .
• Run flat tires may only be u sed on vehicle s that were equipped
with them at the fa ctory . The vehicle must have a chassis de signed
for run flat tires and a factory -installed tire pressure monitoring
system* that indicates a loss of tire pressure. In correct use of run
flat tires can lead to vehicle damage or accidents . Check w ith an
autho riz ed 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 wheel s. Mixing tire types is not permitted .
0 Note
• For techn ica l reaso ns, it is not genera lly poss ib le to use t he
whee l rims from other vehicles. This can hold true fo r wheels of the
same vehicle type .
• I f the s pare t ire is d ifferent from the tires that you have mounted
on your vehicle ( fo r example win te r ti res or wide p rofile tires), then
use the spa re tire for a short period of time on ly and drive with extra
care. Replace t he flat tir e w ith the tire matching the others o n your
vehic le as soon as possib le.
• If you s hould put different whee ls a nd tires on your ve hic le (e.g.
winter wheels and tires), you must be certain that the whee ls and
t ires are co mpa tibl e w ith the tire pressure mon itor in g syste m*.
Otherwise the system w ill reg ister a malfunction and a fault
m essage w ill be d isplayed . For more info rma tion, co ntact your Aud i
dea ler.

• When installing new tires, be careful not to damage the va lves or
tire p ressu re m on itoring system senso rs* .
• N ever drive without the valve stem cap. The valves could get
da mage d.
• I f the sensors must be replaced, then the valve must also be
r eplaced at the same time.
