200 Tires and wheels
handling when in good condition and properly
inflated
¢ .&. .
We recommend that all work on tires and
wheels be perfo rmed by an authorized A udi
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 technica l requirements for
installing or changing tires and r ims.
Replacing tires and wheels
Tires should be rep laced 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.
A lways buy rep lacement radial tires that have
the same specifications as the tires approved
fo r 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.
Aud i-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 (q page 193) lists specifica­
tions of the tires approved for the Audi mod­
els covered by your Owner's Literature .
The tire pressure labe l located on driver's side
B-pillar (¢ page 193, fig. 150) lists the speci­
f ications of the orig inal equipment tires in­
stalled on your veh icle at the time it was man­
ufactured .
Federal law requires tire manufacturers to
place standardized information on the s ide­
wall of all tires q fig. 152. This information
identifies and describes the fundamental
characterist ics, the quality grade of the tire
and also provides a tire ident ificat ion number
fo r safety standard certificat ion 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
sidewa ll, for examp le:
P235 / 35 R 19 91 Y
This conta ins 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/w idt h ratio in percent (aspect ra-
t io)
R Tire construct ion: Radial
19 Rim diameter code (in inches)
91 Load rating code
Y Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF") indicates
t h at the t ire is a"Reinforced" or an "Extra
Load " tire
M+S (or "M/5") Indicates that the ti re has
some mud and snow capability
The tires could also have the information of
direction of rotat ion q page 189.
Tire manufacturing date
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 examp le, 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
q
.&. 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)
T up to 118 mph (190 km/h)
u up to 124 mph (200 km/h)

to 130 mph (210 km/h)

206 Tires and wheels
and handling under a variety of driving condi­
tions. 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 o f 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 regularly checked and maintained . Tire pres·
sures should be checked at least once a
month and always before a long trip
~ page 195, Checking tire pressure.
What you can do to avoid tire and rim
damage
L ow aspect ratio t ires can be damaged more
ea5i ly by impact with potho le5, curb5, gullie5
or ridges on the road, particularly if the tire is
underinflated .
In order to minimize the occur rence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following precau­
tions :
- Always maintain recommended inflation
pressures. Chec k your tire pressure every
2.000 miles (3.000
km) and add air if neces ­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
t h ro ugh or over such obstacles can damage
yo ur tir es. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
tir es or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ir e as soon as possible.
- Inspect your t ires 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
tire failure. If you believe that a
tire may have been damaged, replace the
tire as soon as possible.
- 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 h igh performance
t ir es or iginally installed on your vehicle are in­
tended for maximum dry and wet road per­
fo rmance and handling . They are not suitable
for cold, snowy or icy weather conditions. If
you drive under those circumstances, you
sho uld equ ip your vehicle with all-season or
winter tires, which offer better traction unde r
those conditions. We suggest you use the rec ­
ommended snow or all-season t ires specified
for your vehicle, or their equivalent .
Refer to~
page 203 for more de tailed infor­
mation regarding winter tires.
Tire pressure
monitoring system
General notes
Each tire, including the spare (if provided),
sho uld be checked monthly when co ld and in­
flated to the inflation pressure recommended
by the veh icle manufact urer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire in ­
flat io n pressure label, you should dete rmine
the proper t ire inflation pressure for those
t i r es.).
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low tire
pressure telltale when one or more of you r
t ir es is significantly under-inflated. According -
ly, when the low tire pressure telltale ..,.
