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
New tires and wheels have to be broken in .

The tires and rims are essential parts of the
vehicle's design . The tires and rims approved
by Audi are specially matched to the charac­
teristics of the vehicle and can make a major .,..

contribution to good road holding and safe
handling when in good condition and properly
inflated
¢ .&. .
We recommend that all work on tires and
wheels be performed by an authorized Audi
dealer. They are familiar with recommended
procedures and have the necessary spec ial
too ls and spare parts as well 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 rims.
R eplacing t ires and w heels
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 265.
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 251.
Audi-approved specification tires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold­
ing, driving characteristics, and safety of the
veh icle. The table
(¢page 251) lists spec ifica­
tions of the t ires approved for the Audi mod­
els covered by your Owner's Literature .

Federal law requires t ire manufacturers to
p lace standard ized information on the s ide­
wall of all tires¢

Tire specifications
Knowledge of tire specifications makes it eas­
ier to choose the co rrec t tires . Radial ti res
have the tire specifications marked on the
sidewa ll, for examp le:
P235 / 60 R 18 103 H
This co nta ins the following information:
P Indicates the tire is for passenger cars
(where app licab le)
235 Nom inal tire width i n mm of the tire
from sidewall edge to sidewall edge. In
general, the larger the number, the wider
the tire
60 Height/w idth ratio in percent (aspect ra -
t io)
R Tire construct ion: Radial
18 Rim diameter code (i n inches)
103 Load ra ting code
H Speed ra ting letter code
XL (or "xl", "EXTRA LOAD", or "RF" Indicates
t h at the t ire is a "Reinfo rced" or an " Ext ra
Load " tir e
M+S (or "M/S") Indicates that the tire has
some mud and snow capab ility
The tires could also have the informat ion of
direction of rotat ion
¢ page 247 .
Tire manufacturing d ate
The manufact uring date is also indicated on
the tire sidewall (possibly only on the
inner
s ide of the wheel):
"DOT ... 2213 .. . " means, for example, that the
tire was produced in the 22nd week of 2013.
Speed rating (letter code )
The speed rating letter code on the whee ls in­
dicates the maximum permissible road speeds
¢ .&. in Winter tires on page 263.
P up to 93 mp h (150 km/h)
Q up to 99 mph (158 km/h)
R up to 106 mph (170 km/h)
S up to 110 mph (180 km/h)

264 Tire s and wheel s
driving a few yards and correct if neces­
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 . ..,.
