-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 t ire 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.

Please note that summer and winter tires
are designed for the cond itions that are
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard 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 th ese
items are availab le as factory -installed equip­
ment (whether installed or not) .
Aspect ratio
means t he 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 separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire . typ
ica 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 co ld tem­
peratures, cracks ca n form on the tread
bars, res ulting in permanent tire damage
that can cause loud driving no ise and un­
balan ced t ires. Audi is not responsible for
th is type of damage .
Cold tire inflation pressure
means the tire p ressu re recommended by t he
vehicle manufacturer fo r a tire of a des igna ted
s iz e that has not bee n driven for more than a
coup le of miles (k ilometers) at low speeds in
t h e three hour period before the tire pressure
is measured or adjusted.
Curb weight
mea ns the we ight of a motor ve hicl e 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
me ans 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 -c a rry ing c apac ity of a s ingle
axle system , measured a t the tire-ground in­
terfaces.
Gross Vehicle Weight Rating ("GVWR ")
mea ns the maximum total loaded we ight of
t h e ve hicl e. .,.

-If the ti re is not flat and y ou do not have
to change a wheel immed iate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Dr iving without va lve stem caps can cause
damage to the t ire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secu re ly
mounted on the va lve.
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption.
Tires and vehicle load limits
There are limits to the amount of load or
weight t hat any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the ve hicle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle. These
load limits a re tech nica lly referred to as the
ve hicle's
Gross Veh icle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
ve hicle, all factory installed accessories, a full
tank of f uel, oil, coo lant and othe r fluids plus
max imum load. The maximum load includes
the number o f passenger s that the ve hicl e is
intended to carry ("se ating capacity") w it h an
assumed weig ht o f 150 lbs (68 kg) for each
passenger at a designated seating position
and the tota l weight of any luggage in the ve­
h icle. If you tow a trailer, the weight of the
trailer hitch and the tong ue weight of the
Tire s an d wheel s 281
loaded tra ile r must be included as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating (" GAWR") is
the max imum load th at can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are l iste d on the
s af ety comp liance s tic ke r la bel lo cated on the
driver's side 8 -pillar . Your Audi has 5 seating
positions, 2 in the front and 3 in the rear fo r
total seating capacity of 5. On vehicles with
s ix seats*, your vehicle has two front seats,
two seats in the second row seat ing and two
seats in the th ird row seati ng. On veh icles
with seven seats*, your vehicle has two front
seats, t hree seats in the second row s eating
and two seats in t he third row seating. Ea ch
seat ing pos itio n has a se at belt
~page 174,
Safety be lts .
The fact that ther e is a n upper limit to you r
vehicle's G ross Vehicle Weigh t Rati ng means
that the to tal weig ht of whatever is bei ng car­
ried in the vehicle ( in cl ud ing the weight of a
trailer hitch and the tongue weight of the l oa ded trai le r) is limite d. The more passen­
gers in the vehicle or passengers who are heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage.
The tire pressure label on your Audi also lists
the max imum combined weight of all of the
occupants and luggage or other cargo that
t h e ve hicle can carry. Fo r the locat ion of the
label

A WARNING
Overloading a veh icl e can cause loss of ve­
h icl e cont ro l, a crash or o ther accide nt, se­
rio us pe rson al inj ury, a nd eve n death .
- Ca rrying more we ight tha n your ve hicle
was des igned to carry w ill prevent the
veh icle from h andling proper ly and in ­
crease the risk of the loss o f vehicle con ­
trol.

driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so .
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex­
tremely low. If you do dr ive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severely dam­
age the wheelhouse and other parts of
the veh icle.
(!) Tips
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-whee l dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If different rims are fit ­
ted, the correct wheel bolts with the r ight
l ength and correctly shaped bolt heads must
be used. This ensures t hat wheels a re fitted
secure ly and that the brake system f unctions
correctly .
I n ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
<=?page 318.
.&_ WARNING
Improperly tightened o r maintained wheel
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specified
torque. -
On ly use wheel bolts that be long to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct tightening
torque for the whee l bolts to reduce the
risk of a whee l loss. If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tightening torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the wheel bolts is 120 ft lb ( 160 Nm) with a to le rance of
± 7,4 ft lb( ± 10 Nm) . T orque wheel bolts
diagonally. After changi ng a wheel, the
torque m ust be che cked as soon as possi­
ble with a to rque wrenc h - preferab ly by an
a uthorized Audi dea le r or q ualified work­
shop.
Low aspect ratio tires
Your Audi is factory-equipped w ith low aspect
ratio tires. These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and hand ling under a variety of d riving condi­
tions . As k your au thor ized A udi dealer for
more de tails .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or l ess in the tire's s ize
designation. The n umeral rep resen ts the ratio
of the tire's s idewa ll height in relation to its
tread width exp ressed in percentage . Conven ­
t iona l tires have a he ight/width ratio of 60 or
more.
The performan ce of l ow-a spect-r atio tire s is
particularl y sen sitive to imp roper inflation
pre ssure. It is therefo re important that low
a spect ratio tires are inflated to the specified
pressure and th at the inflation pressure is
regularly checked and mainta ined. Tire pres -
s u res should be checked at least onc e a ..,.
