Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over c urbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
.,.Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(D Note
-Please note that summer and winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­
crease the elasticity of summ ­
er tires, which affects traction
Wheels
and braking ab ility. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, result ing in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be
used in winter driving condi­
tions. The surface of the rims does not have sufficient corro­
sion protection for this and
could be permanently dam­
aged by road salt or sim ilar
substances.

@Composition of the tire cord
and materials
The number of plies indicates the
number of rubberized fabric lay­
ers in the tire. In general: the
more layers, the more weight a
tire can carry . Tire manufacturers
must also specify the materials
used in the tire. These inc lude
steel, nylon, polyester and other
materials.

Glossary of tire and loading
terminology
Accessory weight
means the comb ined weigh t (in
excess of those standard items
which may be replaced) of auto­
matic transm ission, power steer­
ing , power brakes, power win­
dows, power seats, radio, and
heater, to the extent that these
items are available as facto ry-in­
stalled equipment (whether in ­
stalled or not) .
Aspect ratio
means the ratio of the heigh t to
the width of the tire in percent .
Numbers of 55 or lowe r indicate a
low sidewa ll for improved steer­
ing response and better overall
handling on dry pavement. .,.

use a spare tire* that is the same
circumference as the regular
tires.
&_ WARNING -
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident .
-Only use tires that are more
than six years old when abso-
Wheels
lutely necessary and drive
carefully when doing so .
-Do not use run-flat tires on
your vehicle . Using them when
not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves, rapid acceleration and heavy
braking increase tire wear.

Tire tread circumference and vibration character­
istics can change and cause a tire pressure warn­
ing if:
- the tire pressure in one or more tires is too low.
- the tire has structural damage .
- the tire was replaced or the tire pressure was
changed and it was not stored¢

the indicator light does turn off or turns on again
after a short period of time, drive to an author­
ized Audi dealer or authorized Audi Service Facili­
ty immediately to have the malfunction correct­
ed .
A WARNING
- If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steer ing or braking maneu­
vers . Stop as soon as possible and check the
t ir es and their pressure .
- The driver is responsible for maintaining the
correct tire pressure. You must check the
t ire pressure regularly.
- Under certain conditions (such as a sporty
dr iv ing style, winter cond itions or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.
- Do not use run-flat tires on your vehicle. Us­
ing them when not permitted can lead to
vehicle damage or accidents .

Tire Pressure Monitoring System (S8 plus)
(l) General notes
App lies to : 58 plus
Each tire, including the spare (if provided),
sho uld be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determ ine the proper t ire infla-
tion pressure for those tires). .,.

Emerg ency assis ta nce
There are some restrictions on the use of the
spare tire. The spare tire has been designed spe­
cifically for your type of vehicle. Do not replace it
with the spare tire from another type of vehicle.
There are different types of spare tires availab le
depending on the equipment
c::> page 320.
Remo ving t he spare tire
• Lift the cargo floor by the plast ic handle
~fig. 283.
• Hook the hand le into the luggage compartment
seal.
• Turn the handwhee l counter-clockwise and re-
move it.
• Remove the spare tire.
Sn ow c hain s
For technica l reasons, the use of snow chains on
the compact spare tire is not permitted.
If you have to drive with snow chains and a front
tire fa ils, mount the spare wheel in place of a
rear tire. Insta ll the snow cha ins on the rear tire
that you removed, and install that in p lace of the
front tire that failed.
A WARNING
-After installing a spare t ire, the tire pres­
sure must be checked as quickly as poss ible.
- Do not drive faster than 50 mph (80 km/h)
with a compact spare tire. Driving faster
than that increases the risk of an accident.
- To reduce the risk of an accident, avo id fu ll­
throttle acceleration, heavy braking, and
fast cornering with the compact spare t ire.
- To reduce the risk of an accident, never drive with more than one compact spare tire.
- Norma l summer or winter tires must not be
mounted on the compact spare wheel rim.
A WARNING
- Never use the spare tire if it is damaged or if
it is worn down to the tread wear indicators.
- If the spare tire is more than 6 years o ld,
use it only in an emergency and with ex­
treme caution and careful dr iving.
- The spare tire is intended on ly for tempora­
ry and short-term use. It should be replaced
320
as soon as possible with the normal whee l
and tire.
- For technical reasons, the use of tire chains
on the spare tire is not permitted. If it is
necessary to drive w ith tire chains, the spare
wheel must be mounted on the front axle in
the event of a flat in a rear t ire. The newly
ava ilable front wheel must then be installed
in place of the rear wheel w ith the flat tire.
Installing the tire chain befo re mounting
the wheel and tire is recommended.
- Loose items in the passenger compa rtment
can cause se rious personal injury during
ha rd braking or in an accident. Never store
the inflatable spare tire or jack and tools in
the passenger compartment .
