Tyres and rims  
General information  
Machined, polished or chrome-plated rims  
must not be used in winter conditions. The  
process used to manufacture these types of  
wheel rim does not provide adequate sur-  
face protection against corrosion, and the  
rims can be permanently damaged by road  
salt or similar. This does not apply to rims  
which are supplied from the factory as com-  
plete winter wheels.  
In this Owner’s Manual, the term “wheel” refers  
to the combination of rim and tyre. If only one of  
the above components is meant, the term tyre or  
rim is used.  
Inspect the tyres regularly for damage (cuts,  
cracks or blisters, etc.). Remove any foreign  
bodies embedded in the treads.  
Tyre designations  
If you have to drive over a kerb or similar obsta-  
cle, drive very slowly and as near as possible at  
a right angle to the kerb.  
Damaged rims or tyres must be replaced imme-

Keep grease, oil and fuel off the tyres.  
Mark the wheels before taking them off so that  
they rotate in the same direction when refitted.

WARNING  
Manufacturing date  
Never exceed the maximum approved speed  
for your tyres. This causes the tyres to over-  
heat and can even result in a blow-out – risk  
of accident!  
The manufacturing date may possibly only be in-  
dicated on the inner side of the wheel:

Always adapt your driving style to the pre-  
vailing road and traffic conditions. Drive  
carefully and reduce your speed on icy or  
slippery roads. Even winter tyres lose their  
grip on black ice.  
means, for example, that the tyre was produced  
in the 22nd week of 2025.  
AO or R0  
Tyres with the marking “AO” or “R0” which are  
specially matched to your Audi are supplied with  
your vehicle. Provided that they are used proper-  
ly, these tyres fulfil very high standards in safety  
and handling. Your specialist retailer will be glad  
to provide more information.  
CAUTION  
Please note that summer and winter tyres  
are optimised for the prevailing road condi-  
tions at different times of year. Audi recom-  
mends that you use winter tyres during the  
winter months. At low temperatures, sum-  
mer tyres lose their elasticity and grip, and  
braking performance also suffers as a re-  
sult. Cracks can form in the tread block on  
summer tyres if they are used at very cold  
temperatures, and this can cause perma-  
nent damage to the tyres. An increase in  
New wheels or tyres  
Audi recommends having all servicing of wheels  
and tyres performed by a qualified workshop,  
since they have the necessary special tools and  
replacement parts in addition to trained person-  
nel.  
336  
Wheels  
New tyres do not yet give maximum grip. When  
driving with new tyres, drive at moderate  
speeds and be especially careful during the first  
500 km.  
WARNING  
Do not use steel wheels which are 17 inches  
or larger. Otherwise damage to the vehicle  
and an accident could result.  
All four wheels must be fitted with tyres of the  
same type, size (rolling circumference) and  
preferably the same tread pattern.  
Applies to RS model: All four wheels must be  
fitted with tyres of the same type, size (rolling  
circumference) and tread pattern.  
Tyres should be replaced in pairs and not indi-  
vidually (i.e. both front tyres or both rear tyres  
together).  
Audi recommends the use of Audi Genuine  
Tyres. If you wish to use other tyres, please  
note that the actual size can differ from the  
Use only tyre/rim combinations and match-  
ing wheel bolts approved by Audi. Otherwise  
damage to the vehicle and an accident could  
result.  
For technical reasons, it is not possible to  
use wheels from other vehicles. In certain  
cases, it is not even possible to use wheels  
from another vehicle of the same model.  
It is very important to ensure that the tyres  
you have chosen have adequate clearance.  
When selecting replacement tyres, do not  
rely entirely on the nominal tyre size marked  
on the tyre; with some makes of tyre the ef-  
fective tyre size can differ significantly from  
the nominal dimensions, even though the  
tyres have the same size designation. Inade-  
quate tyre clearance can result in damage to  
the tyres or the vehicle, causing a serious  
safety risk.  
nominal size marked on the tyre ð  
.
If you wish to purchase a different combination  
of rims and tyres than the ones fitted on the ve-  
hicle during production, it is advisable to con-  
sult a qualified workshop beforehand ð  
.
The specifications for the rim/tyre combinations  
approved for your vehicle are listed in the vehi-  
cle's documents (e.g. EC Certificate of Conformity  
or COC document ). The vehicle documents vary  
depending on the country in which the vehicle is  
registered.  
Avoid running the car on tyres that are more  
than 6 years old. If you have no alternative,  
you should drive slowly and with extra care  
at all times.  
1)  
The use of run-flat tyres on your vehicle is  
NOT authorised! Unauthorised use can cause  
an accident or damage your vehicle.  
If wheel trims are fitted after the car is pur-  
chased, ensure that there is an adequate  
flow of air for cooling the brakes – risk of ac-  
cident!  
If the spare wheel* is not the same type as the  
tyres fitted on the car (for example if the car has  
winter tyres or wide-section tyres) you should on-  
ly use the spare wheel* if a puncture occurs, and  
then only for a short period of time. In this case,  
please drive with extra care. Refit a normal road  
wheel as soon as possible.  
If any of the tyres are incorrectly mounted  
on the rims, the tyres may be damaged or a  
blow-out may occur. The tyres must be  
mounted on the rims by trained personnel –  
risk of accident!  
All four wheels must always be fitted with tyres  
of the same type, make and tread pattern, as the  
driveline could otherwise be damaged by the dif-  
ferences in the wheel speeds. For the same rea-  
son, only use a spare wheel* which has the same  
rolling circumference as the normal road wheels.

Changing wheels round  
Tyre wear / damage  
Wheels should be changed round regularly to en-  
sure that the wear is equal on all tyres. Fit the  
wheels from the rear axle on the front axle and  
vice-versa. All the tyres will then last for about  
the same time.  
On tyres with a directional tread pattern, note  
the direction of rotation indicated on the sidewall  
ðpage 358.  
Concealed damage  
Fig. 207 Tyre tread: Tread wear indicators  
Damage to tyres and rims is often not readily visi-  
ble. If you notice unusual vibrations or the car  
pulling to one side, this may indicate that one of  
the tyres is damaged. Reduce your speed imme-  
diately. Inspect the tyres for damage. If no exter-  
nal damage is visible, drive slowly and carefully  
to the nearest qualified workshop and have the  
car inspected.  
Tyre wear  
Inspect the tyres regularly for damage.  
The wear on under-inflated or over-inflated  
tyres is significantly higher.  
Fast cornering, heavy acceleration and hard  
braking all increase tyre wear. If the vehicle is  
driven in this way, check the tread depth every  
5,000 km – 10,000 km.  
WARNING  
If you notice excessive tyre wear, have the  
wheel alignment checked by a qualified work-  
shop.  
Insufficient tread depth or different tread  
depths on different wheels reduce safety. This  
is particularly evident in vehicle handling,  
when there is a risk of aquaplaning in deep  
puddles of water and when driving through  
corners. Braking is also adversely affected –  
risk of accident!  
Have your tyres rebalanced if steering wheel vi-  
brations indicate an imbalance. Otherwise, the  
tyres and other parts of the vehicle may wear  
faster.  
Tread wear indicators  
Tyre pressure  
The original tyres on your vehicle have 1.6 mm  
high tread wear indicators ðFig. 207 running  
across the tread at regular intervals. The letters  
“TWI” or triangles on the sidewall indicate the  
positions of the tread wear indicators.  
When checking the tread depth, you must check  
the tread wear indicators across the entire width  
of all four tyres.  
1)  
The minimum tread depth is reached at the lat-  
est when the tread is worn down to the tread  
wear indicators. Replace the tyres with new ones

WARNING  
the spare tyre inflated to the highest pressure  
approved for the tyre.  
If the wheel bolts have not been tightened or  
serviced correctly, they can come loose, and  
you could lose control of the vehicle – risk of  
accident! For the correct tightening torque,  
refer to ðpage 359, After changing a wheel.  
Make sure that the wheel bolts and threads  
in the wheel hubs are always clean and free  
from grease.  
WARNING  
Always adjust the tyre pressures to match  
your driving style and the load the vehicle is  
carrying.  
Excessive loads can cause you to lose control  
of the vehicle – risk of accident!  
Only use wheel bolts that are designed to  
match the rims on your car.  
Under-inflation, high speeds and heavy  
loads require the tyres to flex more, which  
causes them to overheat. This could cause a

Wheels  
Always have damaged rims repaired by a  
qualified workshop. Never attempt to repair  
or dismantle rims yourself – risk of accident!  
If a driver message is displayed, slow down  
immediately and avoid any severe braking or  
steering manoeuvres. As soon as you can do  
so safely, stop and check the wheel bolts.  
Check your wheels for damage and have any  
damaged wheels inspected and/or replaced  
by a qualified workshop as soon as possible.  
Under certain conditions (e.g. driving at high  
speeds, on ice and snow or on poor road sur-  
faces) the driver message may not appear  
immediately.  
Loose wheel warning  
Applies to: vehicles with loose wheel warning  
Within the limits of the system, the loose wheel  
warning in the instrument cluster warns you if  
one or more of the wheels is no longer properly  
secured.  
It is the driver's responsibility to ensure that  
the wheel bolts are properly secured.  
The loose wheel warning makes use of the ABS  
sensors to compare the vibration of the individual  
wheels. If the system detects one or more loose  
wheels, the driver is alerted by a warning lamp  
and a message in the instrument cluster dis-  
play. If only one wheel is affected, the display will  
indicate its position.  
Note  
If a malfunction occurs in the ESC system,  
the loose wheel warning may also be out of  
action.  
When driving with snow chains, a system  
malfunction may occur.  
Driver messages  
Wheel bolts loose. Please stop vehicle safely  
and check all wheel bolts.  
Winter tyres  
Loose wheel warning for at least one of the  
wheels ð . Use the box spanner from the vehi-  
cle toolkit to check the wheel bolts of all the  
wheels right away. Have the tightening torques  
checked as soon as possible with a torque  
wrench. Until then, drive with caution. For the  
correct tightening torque, refer to ðpage 359,  
After changing a wheel.  
In winter road conditions, winter tyres will con-  
siderably improve the car's handling. Due to their  
type of construction (width, rubber compound,  
tread pattern), summer tyres give less grip on ice  
and snow.  
Winter tyres must be fitted on all four wheels.  
Only use winter tyres of the correct type ap-  
proved for your vehicle.  
Please note that the maximum permissible  
Wheel check active. Please drive on carefully  
After a driver message has been displayed and  
you have checked the wheel bolts, the system  
will check the wheels as you drive. This may take  
a few minutes.  
speed for winter tyres may be lower than for  
summer tyres ð  
in General information on  
page 336. Your specialist retailer can advise  
you of the maximum speed for your tyres.  
After fitting the wheels you must always check  
the tyre pressures ðpage 338.  
Loose wheel warning: fault. See owner's  
manual  
Winter tyres lose their effectiveness when the  
tread is worn down to a depth of 4 mm. The per-  
formance of winter tyres is also severely impaired  
by ageing, even if the tread is still much deeper  
than 4 mm.  
A system fault has occurred. Drive to a qualified  
workshop soon and have the fault rectified.  
WARNING  
If the wheel bolts have not been tightened  
correctly, they can come loose, and you could  
lose control of the vehicle – risk of accident!  
For the sake of the environment  
Summer tyres should be fitted again as soon  
as possible; they give better handling on  
340  
Wheels  
roads which are free of snow and ice. They are  
quieter, do not wear so quickly and reduce  
fuel consumption.  
CAUTION  
Snow chains can damage the rim/hubcap* if  
they make direct contact with it. Remove  
the hubcaps* beforehand. Use snow chains  
which have a protective coating.  
Note  
All-weather tyres can also be used instead of  
winter tyres. Please note that winter tyres  
with the symbol are required by law during  
the winter season in some countries.  
If the air suspension* is defective you must  
NOT drive with snow chains as the vehicle is  
extremely low on the road. Driving with  
snow chains could cause severe damage to  
the wheel housings and other parts of the  
vehicle.  
Snow chains  
Snow chains will improve braking ability as well  
as traction in winter conditions (snow and ice).  
Note  
When driving with snow chains, it may help to  
restrict the ESC ðpage 137.  
Snow chains can be used on the rear wheels on-  
ly.  
Check that the snow chains are correctly seated  
Low-profile tyres  
Applies to: vehicles with low-profile tyres  
after driving for a few yards; follow the instruc-  
tions given by the manufacturer.  
Keep your speed below 50 km/h. Please ob-  
serve the applicable local regulations.  
Low-profile tyres have a lower sidewall and pro-  
vide a wider tread surface and rim diameter than  
other wheel and tyre combinations. This makes  
the car's handling more agile. However, the ride  
may be less comfortable on poor-quality roads  
and tracks, and rolling noise may be louder.  
For technical reasons, snow chains may only be  
used on tyres with certain wheel rim/tyre combi-  
nations (depending on model version):

8.5Jx20  
Rim offset  
20 mm  
Tyre size

Low-profile tyres can be damaged more quickly  
than standard tyres, for example by heavy jolts,  
potholes, manhole covers and kerbs. It is there-  
fore particularly important to ensure that they  
are inflated to the correct pressure ðpage 338.

Only use snow chains with fine-pitch links. The  
links must not protrude more than 10.5 mm  
from the tyres (including tensioner).  
Make sure to check your wheels regularly (every  
3,000 km) for damage such as blisters/tears on  
the tyre sidewalls or deformations/cracks on the  
rims.  
You must remove the snow chains on roads which  
are free of snow; otherwise the vehicle’s handling  
may be impaired and the tyres may be damaged.  
After a heavy jolt, or if any damage occurs, you  
should have the rims and tyres checked and if  
necessary replaced by a qualified workshop.  
WARNING  
Unsuitable or incorrectly mounted snow  
chains can cause you to lose control of the ve-  
hicle – risk of accident!

Applies to: vehicles with tyre pressure loss indicator  
If  appears and the indicator lamp in the  
instrument cluster display flashes for approx.  
one minute and then remains lit after you have  
switched on the ignition or while you are driving,  
there is a fault in the system. Try to store the cor-  
rect tyre pressures ðpage 343. In some cases  
the indicator lamp may not go out until you have  
driven the vehicle for a few minutes after storing  
the pressures. If the indicator lamp does not go  
out or if it comes on again after a short time,  
drive to a qualified workshop without delay and  
have the fault rectified.  
The tyre pressure loss indicator in the instrument  
cluster informs the driver if the tyre pressure is  
too low or a system malfunction has occurred.  
The tyre pressure loss indicator makes use of the  
ABS sensors to compare the rolling circumfer-  
ence and the vibration of the tyres. If changes in  
the inflation pressure are detected on one or  
more tyres, the driver is alerted by an indicator  
lamp and a message in the instrument cluster  
display. If only one tyre is affected, the display  
will indicate its position.  
WARNING  
Each time you change a tyre, change the wheels  
round or change the tyre pressures on your vehi-  
cle (e.g. when switching from partial load to full  
load and vice-versa), you must store the new tyre  
pressures ðpage 343. Monitoring of the tyre  
pressures is based on the tyre pressures you have  
stored. The inflation pressures recommended for  
your vehicle are given on the tyre pressure sticker  
ðpage 338, Fig. 208.  
If the tyre pressure loss indicator appears on  
the display, slow down immediately and  
avoid any severe braking or steering ma-  
noeuvres. As soon as you can do so safely,  
stop and check the tyres and the tyre pres-  
sures.  
It is the driver's responsibility to ensure that  
the tyre pressures are correct. For this rea-  
son you must check the tyre pressures regu-  
larly.  
The rolling circumference and vibration can  
change and cause a tyre pressure warning if:  
Under certain conditions (e.g. driving at high  
speeds, on ice and snow or on poor road sur-  
faces) the tyre pressure loss indicator may  
not appear immediately.  
The inflation pressure in one or more tyres is  
too low.  
The tyres have suffered structural damage.  
The wheels were changed or the tyre pressures  
were changed and the new tyre pressures were  
not stored ðpage 343.  
Note  
If a malfunction occurs in the ESC system,  
the tyre pressure loss indicator may also be  
out of action.  
Only some of the worn tyres have been re-  
placed.  
When driving with snow chains, a system  
malfunction may occur.  
Indicator lamps  
If the indicator lamp lights up, there is a loss  
of pressure on one or more tyres ð . Check the  
tyre(s) and change them if necessary. Check and  
adjust the inflation pressures of all four tyres  
again and store the new tyre pressures  
ðpage 343.  
The tyre pressure loss indicator on your Audi

WARNING  
The tyre pressure monitoring system helps  
the driver to monitor the tyre pressures.  
However, it is always the driver's responsi-  
bility to ensure that the tyres are at the cor-  
rect pressure.  
When you change a tyre or the tyre pressure on  
your vehicle, you must confirm the change on the  
MMI.  
Before storing the new tyre pressures, check  
Never re-adjust the tyre pressure when the  
tyre is hot. This can cause serious damage to

that the current pressures on all four wheels  
correspond to the specified values and adapt  
the pressures to the current load ðpage 338.  
Switch on the ignition.  
Under-inflated tyres flex more than they  
should. This causes them to overheat. This  
can cause tread separation and tyre blow-  
out, which could result in an accident.  
The tyre pressure monitoring system cannot  
warn you of tyre damage or defects that  
could lead, for example, to a tyre blow-out.  
Perform a regular visual check of your tyres.

General information  
Applies to: vehicles with tyre pressure monitoring system  
The tyre pressure monitoring system keeps a  
check on the tyre pressures on the four wheels  
while you are driving.  
After using the tyre repair kit*, the tyre  
pressure monitoring system may malfunc-  
tion. Have the sensors replaced by a quali-  
fied workshop.  
The system uses sensors to measure tempera-  
tures and pressures in the tyres. The sensors  
transmit the data to the control unit by radio.  
The tyre pressure monitoring system displays the  
current pressures and temperatures of the tyres  
on the MMI while the vehicle is moving  
Displaying tyre pressures and temperatures  
Applies to: vehicles with tyre pressure monitoring system  
ðpage 343. In addition, it compares the current  
tyre pressures with the stored tyre pressures and  
warns you via the driver information system if it  
detects a discrepancy ðpage 344.  
Important: The vehicle must be moving.  
Applies to MMI: On the home screen, select  
CAR > Settings & service > Tyre pressure > Dis-

To enable the tyre pressure monitoring system to  
work reliably, it is important to store the correct  
pressure settings.  
Bear in mind that the tyre inflation pressure is al-  
so influenced by the temperature of the tyre. The  
tyre heats up while the vehicle is being driven  
and the tyre pressure will rise accordingly.  
You should always store the tyre pressures if new  
sensors have been fitted or after changing the  
pressures, such as when carrying a different load.  
Before storing the new tyre pressures, check  
WARNING  
that the current pressures on all four wheels  
correspond to the specified values and adapt  
the pressures to the current load ðpage 338,  
Fig. 208. Only adjust and store the pressure of  
the tyres when they are at approximately ambi-  
ent temperature. If the tyre temperatures are  
higher than the ambient temperature, the pres-  
sures should be increased by approx. 0.2 bar  
above the pressures specified on the tyre pres-  
sure sticker.  
Please observe the important safety informa-  
tion and notes ðpage 343.  
Note  
The tyre pressures and temperatures are not  
shown in the display when the vehicle is sta-  
tionary or during the initialisation phase. Hor-  
izontal dashes --.-- will appear instead of the

If the new tyre pressures do not appear on the  
MMI, you will need to drive for about 10 mi-  
nutes so that the sensor signal from the wheels  
can be received again.  
Applies to: vehicles with tyre pressure monitoring system  
If the indicator lamp lights up, the tyre pres-  
sure is too low compared with the reference val-  
ue. Adjust the pressure of the relevant tyre(s) at  
the next opportunity and store the pressures  
ðpage 344.  
During this initialisation phase, --.-- will be

Avoid unnecessary braking and steering manoeu-  
vres. Adapt your driving style to the prevailing  
conditions. As soon as you can do so safely, stop  
and check the tyre(s). If it is possible to continue  
driving, you should take the vehicle to a qualified  
workshop and have the defective tyre(s) replaced  
immediately.

If the indicator lamp  appears after you have  
switched on the ignition or while you are driving  
and the indicator lamp flashes for approxi-  
mately one minute and then remains lit, there is  
a fault in the system. This fault can have the fol-  
lowing causes:  
If the display appears at the end of the initiali-  
sation process, this means that the system can-  
not detect the wheel sensors required to moni-  
tor the pressures. This can happen if one or  
more of the tyres fitted does not have a sensor  
or the sensors are incompatible.  
One of the wheel sensors or another compo-  
nent may not be working.  
Snow chains interfere with the signals trans-  
mitted by the sensors and can prevent the sys-  
tem from functioning properly.  
The tyre pressure monitoring system may be in-  
operative due to radio interference.  
Radio systems operating on the same frequen-  
cy, such as radio headphones or two-way radios  
inside the vehicle, produce strong electromag-  
netic fields which cause temporary interfer-  
ence.  
The indicator lamp  and the message will  
disappear as soon as the tyre pressure monitor-  
ing system is available again. If the fault persists  
and the indicator lamp  stays on, you should  
drive to a qualified workshop and have the fault  
rectified.
