your veh icle and in this manua l and the kind
of driving you p lan to do .
Neve r e xcee d the m ax imum inflati on pres­
s u re list e d on th e tir e s ide wall f or a ny r ea­
s on.
Remember that the vehicle manufacturer, not
the tire manufacturer , determ ines the co rrect
tire pressure for the t ires on your veh icle .
It is important to check the tire pressure when
the tires a re cold .
- Read the required t ire pres sure from the tire
pressure label. The ti re pressure label is lo­
cated on the driver's side 8-p illar . The t ire
pressure label lists the recommended cold
t ire inflat ion p ressu res for the veh icle at its
maximum capacity we ight and the tires that
were on you r vehicle at the time it was man­
ufactured . For recommended tire pressures
for normal load condit ions, please see chap­
ter
9 page 199.
-Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the a ir pressure gauge on the valve.
- T he tire pressures should on ly be checked
and adjusted when the tires are cold. The
s li ghtly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying .
- Reinsta ll the va lve stem cap on the valve.
When should I check the tire pressur e?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always befo re starting a journey. Do not
forget to check the tire pressure for the spare wheel.
When should I ad ju st th e tire p re ss ures?
Adj ust the tire p ressure to the load you are
carry ing . After chang ing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then in iti­
alize the new tire pressures in th e tire pres­
sure monito ring system*
c> page 213.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the
Rt] warning symbol appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the hand ling of the vehicle and
stopping abi lity.
- I nco rrect tire pressures and/or underin­
f lation can also lead to sudden t ire fail­
ure, including a blowout and sudden de­
flation, ca using loss of vehicle contro l.
- The driver is responsible for the co rrect
tire pressures for all tires on the veh icle.
The applicable pressure values are locat ­
ed on a sticker on the driver's side B -pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the tire pres­
sure monitoring system * can work cor­
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re pressure monitor­
ing system*.
- Always inflate t ires to the recommended
and correct t ire p ressure before dr iving
off.
- Driving with underinf lated tires bend
mo re, letting them get too hot resulting
in tread sepa ration, s udden tire failure
and loss of cont ro l.
- E xcessive speed and/overloadi ng can
cause heat b uild- up, sudden tire failure
and loss of cont ro l.
- I f the tire pressure is too low or too high,
the t ires will wear prema turely and the
vehicle wi ll not handle well. ..,

-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 th at load limits are
no t 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 203
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 . Yo ur Audi has 5 seating
positions, 2 in the front and 3 in the rear fo r
total seating capacity of 5. Eac h seating posi ­
tion has a seat be lt
c::> page 104, Safety bel ts.
T he fac t that there is an upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car ­
ried in the vehicle ( includ ing the weight of a
trai ler hitch and the tongue weight of the
l oaded tra ile r) is lim ited . The more passen ­
gers in the vehicle or passe ngers w ho are
heavi er than the standard we ights assumed
mea n that less we ight can be ca rried as lug­
gage.

A WARNING
-=
Overloading a vehicle can cause loss of ve -
h icle cont ro l, a c rash or other accide nt, se ­
rious pe rsonal injury, and even death.
- Ca rrying more we ight than your vehicle
was des igned to carry wi ll prevent the
veh icle from handling pr oper ly 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
ve hicle w it hi n a safe distance.
- Tires o n a vehicle that has been over load­
ed can fail s uddenly, incl uding a blowout
a nd sudden defla tion, causing loss of
con trol an d 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 vehi­
cle's placard (tire inflation pressure label)
¢ page 199,
fig. 152.
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
r:=> page 199, fig. 152.
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 50
(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
to determine how this re­ duces the available cargo
and luggage load capacity of
your vehicle.
... Check the tire sidewall
(¢ page 206, fig. 156) to de­
termine the designated load rating for a specific tire.

206 Tires and whe els
& WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious persona l 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
yo ur risk of "hydroplan ing" and loss of
control.
- Always keep chemicals that can cause tire damage, such as grease, oil, gasoline and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly , especially at high
speeds . T ir es that are more t han 6 years
o ld can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used ti res on yo ur vehicle if
yo u 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.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .

We recommend that all work on t ires and
wheels be performed by an authorized A udi
dealer. They are familiar with recommended
procedures and have the necessary spec ial
too ls and spare parts as we ll as the proper fa ­
cilities for dispos ing of the old tires .
Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
R eplacing t ires and wheel s
Tires shou ld be rep laced at least in pairs and
not individua lly (for example both front tires
or both rear tires together).
Be s ure to read and heed the information to
the tire pressure monitoring system*
¢ page 213.
Always buy rep lacement radial tires that have
the same specifications as the t ires approved
for your ve hicle by Audi. Replacement tires
must always have the same load rating speci ­
fication as the original equipment or approved
optional tires listed in the table
¢ page 199.
Audi-approved specification tires are specially
matched to your vehicle and its load limits ,
and can contribute to the important road hold­
ing, driving character istics, and safety of the
veh icle. The table

¢ &. .
U.S. DOT Tire Identification Number (TIN)
and tire manufacture date
This is the tire's "serial number". It begins
with the letters "DOT" and indicates that the
tire meets all federal standards. The next two
numbers or letters indicate the plant where it
was manufactured, and the last four numbers
represent the week and year of manufacture.
For example, the numbers 2214 mean that
the tire was produced in the 22nd wee k of
2014. The other numbers are mar keting co­
des that may or may not be used by the tire
manufacturer . This information is used to con­
tact consumers if a tire defect requires a re­
call.
Audi Original tire
Tires with the identification "AO" or "RO" have
been specia lly matched with your Audi . We
recommend using only these tires because
they meet the highest standards regard ing
safety and driving character istics when used
correctly. Your authorized Audi dealer will
gladly provide you with more information.
Tire ply composit ion and materials used
The number of plies indicates the number of
l ayers of rubber-coated fabric in the tire. In

genera l, the greater the number of plies, the
more weight a tire can support. Tire manufac­
turers also must indicate the materials in the
t ir e, which include steel, nylon, po lyester, and
others.
Maximum Load Rating
This number ind icates the maximum load in
kilograms and pounds that can be carried by
the tire.

Maximum Permissible Inflation Pressure
Th is number is the greatest amount of air
pressure that should ever be put in the tire
u nder normal driving conditions.
.&, WARNING ~ -
-Using incorrect or unmatched tires and/
or wheels or improper tire and wheel
comb inat ions can lead to loss of control,
coll is ion and serious personal injury.
-Always use t ires, rims and whee l bolts
that meet the specifications of original
factory- installed tires or other combina­
tions that have been specifically ap­
proved by the vehicle manufacturer.
- 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 emergen cy
and then with special care and at lower
speeds.
- Never mount used tires on your 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 fa ilure
and loss of vehicle control.

-All four wheels must be fitted with radia l
t ires of the same type, size (roll ing cir­
cumference) and the same tread pattern .
Driv ing with different tires reduces veh i­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
t ir es that are mounted on the veh icle -
for example with winte r tires -o nl y use
the spare tire for a short period of time and dr ive wi th extra care. Refit the nor­
ma l road whee l as soon as safely possi ­
ble.
- Never drive faster than the maxim um
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
sudden ly.
- Overloading tires cause heat build- up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are properly inflated and not over or un­
der inflated .
- For technical reasons it is not a lways
poss ible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel tr im 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 ca us­
ing a collision.
- Run flat t ires may on ly be used on
vehicles that we re equ ipped w ith them
at the facto ry. The vehicle must have a
chassis des igned for run flat t ires and a
facto ry-installed tire p ress ure monito r­
ing system* that indicates a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dea ler or
t ire spec ia list to see if your vehicle can be
equipped with run flat tires .
If run flat
t ir es a re used, they must be insta lled on
all four wheels. M ixing tire types is not
permitted.

@ Note
-For technical reasons, it is not generally
possible to use the wheel rims from oth­
er veh icles. Th is can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is d ifferent from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short per iod of time only and drive w ith
extra care. Replace the flat tire w ith the

210 Tire s and wheel s
The relat ive performance of tires depends
upon the actua l conditions of their use, how ­
ever, and may depart sign ificantly from the
norm due to va riat ions in dr iving habits, serv­
ice practices and differences in road character­
istics and climate.
Tr action
The traction grades , from highest to lowest,
are AA, A, Band
C. Those g rades represent the
tire's ability to stop on wet pavement as measured under controlled cond itions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢.&, .
Temperature
The tempera ture grades are A (the h ighest),
B, and
C, represen ting the tire's resistance to
the generat ion of heat and its abi lity to dissi ­
pate heat when tested under controlled cond i­
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden ti re fa il ur e~ .&, .
The grade
C corresponds to a level of perform ­
ance which all passenger ca r tires must meet
u nder the Federa l Motor Veh icle Safety Stand­
a rd No.
1 09. Grades Band A represent higher
l eve ls of performance on the laboratory test
wheel than the minimum required by law .
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering , hydroplan ing or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es­
tablished for a t ire that is properly inflated
and not overloaded . Excessive speed, un­
derinflation, or excessive loading, eithe r
-
separately or in combination, can ca use
heat bui ldup and possib le tire failure .
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F ( 7 °C) we recommend changing to winter
tires.
In some heavy snow areas , local governments
may require true winter or "snow" tires, those
with very deeply cut tread . These tires should
only be used in pairs and be installed on all
four wheels . Make sure you purchase snow
tires that are the same s ize and construction
type as the othe r tires on your vehicle .
Your vehicle is equipped with all wheel drive,
th is will improve traction during winter driv ­
i ng, even with the standa rd t ires. However, we
strong ly recommend that you always equip all
four wheels on you r vehicle wi th cor rectly fit­
ted win ter tires o r all -season tires, when win­
te r road cond itions are expected . This also im­
proves the vehicle's braking performance and
reduces stopping distances.
Summe r tires provide less grip on i ce and
snow.
Winter tires (snow tires) must always be fitted on all four whee ls .
Ask your author ized Audi dealer or qualified
workshop for permitted
winter tir e siz es. Use
on ly rad ial winter t ires .
Winter tires lose their effectiveness when the
tread is worn down to a depth of
O .15 7 inch
(4 mm).
Only drive w ith w inter t ires under winter con ­
ditions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat ti re, see notes on spare
whee l¢
page 206 .
Please always remember that winter tires may
have a lower speed rating than the tires origi-
nally installed on your vehicle at the time it .,.
