Wheels and Tires
General information
1>-(heck your tires regularly for
damage (punctures , cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­ proach the curb at an angle.
1>-Have faulty tires or rims re­
placed immediately.
1>-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.
1>-Lay tires flat when storing and
store them in a cool , dry location
with as little exposure to light as possible.
_&. WARNING -
-Never drive faster than the
maximum permitted speed
for your tires . This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
166
tions. Dr ive carefully and re ­
duce your speed on icy or slip­
pery roads. Even winter tires
can lose traction on black ice .
(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
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting 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 similar
substances.

@ Audi Original Tires
Audi Original equipment tires
with the designation "AO" have
been specially matched to your
Audi. When used correctly, these
tires meet the highest standards
for safety and handling. An au ­
thorized A udi dealer or author­
ized Audi Service Facility will be
able to provide you with more in­
formation .
® Mud and snow capability
"M/5" or "M+S" indicates the tire

to drive in mud or snow.

cates a winter t ire .
@ Compos ition 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
168
tire can carry. Tire manufacturers
must also specify the materials
used in the tire . These include
steel, nylon, polyester and other
materials .
@Maximum permitted load
This number indicates the maxi ­
mum load in kilograms and
pounds that the tire can carry.
@ Uniform tire quality grade

tr action and temper atur e
resistance

ture ranges

@ Running direction
The arrows indicate the running
direction of unidirectional tires.
You must always follow the speci­
fied running direction

@) Maximum permitted
inflation pressure
This number indicates the maxi­
mum pressure to which a tire can
be inflated under normal operat­
ing condit ions .

c::> .,&..
~ If you would like to equip your
vehicle with a tire/rim combina­ tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur­
chase
c::> ,& .
If the spare tire is different from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­ porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all wheel
drive: all four wheels must be
equipped with tires that are the
same brand and have the same
construction and tread pattern so
that the drive system is not dam­
aged by different wheel speeds. For this reason, in case of emer­
gency, only use a spare tire that has the same circumference as
the regular tires.

A 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
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 al­low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage

tor
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.
-Have an authorized Audi dea ler
or authorized Audi Service Facili-
l ) Obey any applicable regulations in your
country.
Wheels
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running d irec­
tion
i:::> fig. 145. The letters "TWI "
or triang les on the tire sidewall
indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l ) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
i:::> .&..
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires, install the tires from the rear axle ..,.

The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switch ing between partial and full load
pressure) or after changing or replacing a tire on
your vehicle
c:::> page 184. The tire pressure moni­
toring system only monitors the tire pressure you have stored . Refer to the tire pressure label for
the recommended tire pressure for your vehicle
c:::> page 176, fig. 147.
Tire tread circumference and vibration character­ istics can change and cause a t ire 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

_& WARNING
- If the tire pressure indicator appea rs in the
display, reduce your speed immediate ly and
avoid any hard steering or braking maneu­
vers. Stop as soon as possib le and check the
t ir es and their pressure.
- The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regularly.

'
-Under certain conditions (such as a sporty
driving style, w inter conditions or unpaved
roads), the tire pressure monitoring system
ind icator may be delayed .
- Do not use run-flat tires on your vehicle. Us­
ing them when not permitted can lead to
veh icle damage or accidents.
(D Tips
- The tire pressure monitor ing system can al­
so stop working when there is an ESC mal­
function.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitor ing system in your
Audi was calibrated with "Audi Or iginal
Tires"
c:::> page 173. Using these tires is rec­
ommended.
