192 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 .

inflated¢&..
We recommend that all wo rk on tires and
wheels be perfo rmed by an au thorized A udi
dea ler. They are familiar with recommended
proced ures and have the necessary special
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 technica l requirements for
insta lling or changing tires and r ims.
R eplacing t ire s an d wheel s
Tires s hou ld be rep laced at least in pairs and
not individua lly (for example both front t ires
or both rear tires together).
Be sure to read and heed the information to
the t ire pressure monitor ing system
¢page 199.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your ve hicl e by Audi. Replacement t ires
must always have the same load rating speci­
fication as the original equipment or approved optional tires listed in the table
¢ page 185.
Aud i-approved specifica tion ti res are specially
matched to you r vehicle and its load limits,
and can contribute to the important road ho ld­
ing, driving characteristics, and safety of the
vehicle. The table
( q page 185) lists specifica­
tions of the t ires approved for the Audi mod­
e ls covered by your Owner's Literature .
The tire pressure labe l located on driver's side
B-pillar
( q page 185, fig. 139) lists the speci­
fications of the orig inal equipment tires in­
stalled on your veh icle at the time it was man­
ufactured .
Federal law requires t ire manufacturers to
place standard ized information on the s ide­
wall of all tires
q fig. 142. This information
ident ifies and describes the fundamental
characterist ics, the quality grade of the tire
and a lso provides a tire identificat ion number
for safety standard certificat ion and i n case of
a recall.
Tire s an d wheel s 193
Tire specification s
Knowledge of tire specifications makes it eas­
ier to choose the co rrect tires. Radial tires
have the tire specifications marked on the
sidewa ll, for examp le:
P245 / 45 R 17 95 H
This conta ins the following information:
P Indicates the tire is for passenger cars
2 45 Nominal tire width in mm of the tire
from sidewall edge to sidewall edge. In general, the larger the number, the wider
the tire
45 Height/w idt h ratio in percent (aspect ra-
tio)
R Tire construction: Radial
17 Rim diameter code (in inches)
95 Load rating code
H Speed rat ing letter code
XL (or "xl", "EXTRA LOAD", or "RF") ind icates
that the t ire is a"Re inforced" o r an " Extra
Load " tir e
M+5 (or "M/S") Indicates that the tire has
some mud and snow capabi lity
The t ires could also have the informat ion of
direction of rotat ion
q page 181 .
Tire manuf acturing d ate
The manufacturing date is also indicated on
the tire sidewall (possibly on ly on the
inner
s ide of the wheel) :
"DOT ... 2213 ... "means, for examp le, that
the tire was produced in the 22nd week of
2013.
Sp eed rating (letter code )
The speed rating letter code on the whee ls in­
dicates the maximum permissible road speeds
q .&. in Winter tires on page 197.

Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time
and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- 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 tires that
are properly inflated and not over or un­
deri nflated.
- For technical 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 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 caus­
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them
at the factory . The vehicle must have a
chassis designed for run flat tires and a
factory-installed tire pressure monitor­ 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 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 wheels. Mixing tire types is not
permitted .
Tires and wheels 195
@ Note
-For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 192,
fig. 142 .
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100. •

snow cha ins a re suitab ly covered. Check
the position of the snow chains after driving a few yards and correct if neces ­
sary. Follow the instr uctions from the
snow cha in manufacturer when doing so.
{O) Tips
Where snow cha ins are mandatory oncer­
tain roads, this norma lly also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correc t torque .
The design of whee l bolts is matched to the
factory installed r ims . If different rims are fit ­
ted, the correct wheel bolt s with the r ight
length and correctly shaped bol t heads mus t
be used . This ensures that wheel s are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a d iffe rent vehicle -even if it
i s the same model
Q page 228.
A WARNING
Imprope rly tig htened o r maintained whee l
bolts can be come loose ca using loss of
cont ro l, a co llision and serious person al in­
jury .
- Always keep the w heel bol ts and the
t h reads in t he wheel hubs clean so the
wheel bolts can t urn easily and be p rop ­
er ly t ightened .
- N ever grease or oil the wheel bo lt s an d
the threads in the wheel h ubs. They can
become loose w hile d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l bolts that be long to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
- Always mai ntai n the co rrect tighte ning
torq ue for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor- que of the whee
l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig hte ning torq ue is
too high, the w heel bolts a nd threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for t he whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torque whee l bolts diago­
nally . After changing a whee l, the to rq ue
must be checked as soon as possible with a
torque w rench - prefe rably by an author­
iz ed A udi dealer or quali fied workshop .
Low aspect ratio tires
Your Audi is factory-eq uipped w ith low aspect
ratio tires. These tires have b een tho ro ughly
tested and been se lected specifically for your
model for their supe rb performance, road fee l
and hand ling under a variety of driving condi­
t ions . Ask your author ized Audi dealer for
more de tails .
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire 's s ize
designation . The numera l rep resents the ratio
of the tire 's s idewa ll height in relation to its
t read width exp ressed in percentage. Conven­
tiona l tire s have a he igh t/w idth rat io of 60 or
more.
The p erformance of low-a spect-ratio tire s is
particularly sensitiv e to improper inflation
pre ssure. It i s ther efore important that low
aspect ratio tires are inflated to the specified
pre ssure and that the inflation pre ssure i s
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always before a long trip
Q page 187, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith po tholes, curbs, gul lies ..,.
