- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al
ways stop as soon as it is safe to do so and check the wheels and tires for dam
age.

Glossary of tire and loading terminology
Acces sory weight
means the comb ined we ight (in excess of
those standard items which may be rep laced)
of au toma tic tra nsmission, power steer ing,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory -installed equip
ment (whether installed or not) .
Aspect ratio
means the ratio of the he ight to the w idth of
the tire in percent . Numbers of 55 or lower in
dicate a low sidewall for improved steering re
sponse and better overall handling on dry pavement .
Bead
means the part of the ti re that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typica
l in those seasons. Audi recommends
using winter tires during the winter
months. Low temperatures signif icant ly
decrease the e lasticity of summer tires,
which affects tract ion and brak ing ability.
If summer tires are used in very cold tem peratures, cracks ca n form on the tread
bars, resulting in permanent tire damage
that can cause loud driving no ise and un
balanced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pre ssure
means the t ire p ressure recommended by the
vehicle manufacturer fo r a tire of a des ignated
s ize that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
the three hour period before the tire pressure
is measured or adjusted.
Curb weight
means the we ight of a motor ve hicle w ith
standard equipment including the max imum
capacity of fuel, oil, and coolant, air condi
tioning and additional weight of optiona l
equipment.
Extra load tire
means a t ire design to operate at higher loads
and at h igher inflation pressures than the cor
responding standard tire . Extra load tires may
be identified as "XL", "x l" , "EXTRA LOAD", or
"RF" on the sidewall.
Gross A xle Weight Rating ("GAWR ")
means the lo ad -carry ing capacity of a s ingle
axle system , measured at the tire-ground in
terfaces.
Gr oss Vehicle Weight Rating ("GVWR ")
means the maximum total loaded we ight of
t h e vehi cle. .,.

258 Tires and wheels
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
wheel alignment checked by an authorized
Audi dealer or qualified workshop .
All-wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see Qpage 202 .
.&_ WARNING
Sudden tire failure can lead to loss of con
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of"hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you a re not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels

sary. Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to
veh icles with all-wheel dr ive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled rims . If different rims are fit
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
¢ page 295.
.&_ WARNING
Improperly tig htened or maintained wheel
bolts can become loose ca using loss of
cont ro l, a co llision and serious p ersona l in
Jury.
- Always keep the wheel bolts and the
threads in t he wheel hubs clea n so the
wheel bolts can tu rn easily and be prop
erly tigh tened.
- N ever grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use wheel bolts that be long to the
rim being installed.
- N ever use different whee ls bolts on your
vehicle.
- Always mai nta in the co rrec t tighte ning
tor que fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bo lts is too low, they
can loosen and come out when the veh i- cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be
come loose.
(D Note
The specified torque for the whee l bolts is
105 ft lb (140 Nm) with a to lerance of
± 7,4 ft lb(± 10 Nm). Torque wheel bolts
diagonally . After changing a wheel, the
torque must be checked as soon as poss i
ble with a to rque wrench -preferab ly by an
a uthorized Aud i dea le r or qualified wor k
shop.
Low aspect ratio tires
Your A udi is factory -eq uipped w it h low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi
t ions . Ask your authorized Audi dealer for
more details .
The low aspect ratio of these tires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
t read width exp ressed in percentage. Conven
tiona l tires have a he ight/w idth rat io of 60 or
more.
Th e performanc e of low-a spect-ratio tire s is
pa rticularly sensi tive to improp er inflation
pre ssure. It i s ther efor e important that low
a spe ct ratio tir es are inflated to the spe cified
pre ssure and that the inflation pre ssure i s
regula rly checked and mainta ined. Tire pre s
sure s should be checked at lea st once a
month and al way s befo re a long trip
¢ page 2 53, Checking tire pressure.
What you can do to a void tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w ith potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.
