200 Tires and wheels
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 special
tools and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary
information about technical requirements for
installing or changing tires and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and
not individually (for example both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system
¢page 201.
Always buy replacement radial tires that have
the same specifications as the tires approved
for your vehicle 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 193.
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
vehicle. The table(¢
page 193) lists specifica­
tions of the tires approved for the Audi mod­
els covered by your Owner's Literature .
The tire pressure label located on driver's side
B-pillar (
¢ page 193, fig. 151) lists the speci­
f ications of the original equipment tires in­
stalled on your vehicle at the time it was man­
ufactured.
Federal law requires tire manufacturers to
place standardized information on the side­
wall of all tires¢
fig. 153. This information
identifies and describes the fundamental
characteristics, the quality grade of the tire
and also provides a tire identification number for
safety standard certification and in case of
a recall.
Tire specifications
Knowledge of tire specifications makes it eas­
ier to choose the correct tires. Radial tires
have the tire specifications marked on the
sidewall, for example:
P235 / 35 R 18 91 Y
This contains the following information:
P Indicates the tire is for passenger cars
235 Nominal tire width in mm of the tire
from sidewall edge to sidewall edge. In general, the larger the number, the wider
the tire
35 Height/width ratio in percent (aspect ra-
tio)
R Tire construction: Radial
18 Rim diameter code (in inches)
91 Load rating code
Y Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF") indicates
that the tire is a"Reinforced" or an "Extra
Load" tire
M+S (or "M/S") Indicates that the tire has
some mud and snow capability
The tires could also have the information of
direction of rotation¢
page 189.
Tire manufacturing date
The manufacturing date is also indicated on
the tire sidewall (possibly only on the
inner
side of the wheel):
"DOT ... 2210 ... " means, for example, that
the tire was produced in the 22nd week of 2010.
Speed rating (letter code)
The speed rating letter code on the wheels in­
dicates the maximum permissible road speeds
¢ .&. in Winter tires on page 204.
P up to 93 mph (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)

conditions. Ask your authorized Audi dea ler
for more details.
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's size
designation. The numeral represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
tional tires have a height/width ratio of 60 or
more.
The performance of low-aspect -ratio tires is
particularly sensitive to improper inflation
pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the inflation pressure is reg ­
ularly checked and mainta ined. Tire pressures
should be checked at least once a month and
a lways before a long t rip
~ page 195, Check­
ing tire pressure.
What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
eas ily by impact with potholes, curbs, gullies
or ridge5 on the road, particu larly if the tire i5
underinflated.
I n order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2.000 miles (3.000 km) and add air if neces­
sary.
- Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authori zed Audi dealer. Rep lace a damaged
tire as soon as possible.
- Inspect your tires every 2.000 miles (3.000 km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ich could eventu ­
ally cause t ire failure . If you believe that a tire
may have been damaged, replace the
tire as soon as possib le.
- These tires may wear more quickly than oth­
ers.
- Please also remember that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices .
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
t ir es originally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling . They are not suitable
for cold, snowy or icy weather conditions . If
you drive under those c ircumstances, you
should equ ip your vehicle w ith winter t ires,
which offer better traction under those condi­
tions . We suggest yo u use the recommended
snow tires specified for your vehicle, or their
equivalent.
Refer to~
poge 203 for more detailed infor­
mation regarding winter tires.
Ti re pressure
monitoring system
General notes
E ach tire, including the spare (if provided),
shou ld be checked monthly when cold and in­
flated to the inflat ion pressure recommended
by the vehic le manufacturer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different si ze than the
size indicated on the vehicle placard or tire in­
flat ion pressure label, you should determine
the proper t ire in flation pressure for those
t ir es .) .
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi­
nates, you shou ld stop and check you r tires as

Tightening wheel bolts
.,. Fit the wh eel b olt wrench ove r the wheel
bolt and push it down as far as it will go
1l.
.,. Close your grip around the
end of the
wrenc h handle fo r maximum torque and
turn each wheel bolt
clockwi se u nti l it sits
t ight.
H ave the
tightening torque of the whee l bolts
checked as soon as possible with a torque
wrench . It shou ld be 120 Nm.
Chec k the
tire pre ssure as soon as possible.
Return the vehicle tool kit to its proper place.
A WARNING
Loose ning t he wheel bo lts is prohib ited;
da nger of an accident!
@ Tips
- Never try and use the hexagona l socke t
i n the handle of the screwdr iver to loos­
en or tighten the w heel bolts.
- If yo u have dete rm ined t hat wheel bolts
a re cor roded and difficult to t urn, the
bo lts must be rep laced befo re checking
the to rque.
- Unti l the tig hte ning torque is checked,
d rive at redu ced speeds as a pre caution.
Notes on wheel change
Pl ease read the information¢ page 199, New
tires and replacing tires and wheels,
if you are
going to use a spare tire which is different
from the tires on your veh icle.
Afte r you change a tire:
- Check the tire pressure on the spare imme­
dia tely after mounting.
- Have the whee l bolt t ightening torque
chec ked w ith a torq ue wrench as soon as
poss ible by your author ized A udi dealer or a
qu alified service sta tion.
1 ) You need th e appropr iate adapter to tighte n the a nti­
t h eft wheel bolts
c:, page 216.
What do I do now? 219
- With stee l and alloy whee l rims, the whee l
bolts are correctly tightened at a torque of
90 ft lb (120 Nm) .
- If you notice while changing a tire that the
wheel bo lts are corroded and difficu lt to
turn, then they should be rep laced before
you check the tightening torque.
- Replace the flat tire with a new one and
have it installed on your vehicle as soon as
possible. Remount the wheel cover.
Until then , d riv e with e xtra care and at re­
duced speeds.
A WARNING
- If you are going to equ ip your vehicle
with tires or rims which differ from those
which were facto ry installed, then be
sure to read the information ¢

New tires and replacing tir es and
wheels.
- Always sto re the tools secu rely in lug­
