& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always u se tires , rims and wheel bolts that meet the specifica ­
tions of original factory -installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds . Tires that are more than 6 years old can
only be used in an emergen cy and then with special care and at
lower speed s.
• Never mount used tires on your vehi cle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same type ,
size (rolling circumference ) and the same tread pattern. Driving
with different tires reduces vehi cle handling and can lead to a loss
of control.
• If the spare t ire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the ma ximum speed for wh ich the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s cause heat build -up , sudden tire failure ,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For technical reasons it is not always possible to use wheel s
from other vehicles - in some cases not even wheels from the
same vehicle model.
& WARNING (continued )
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassis designed
for run flat tires and a factory-installed tire pressure monitoring
s ystem that indicate s a loss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or ac cidents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equ ipped with run flat tires . If run flat tires are used , they must
be installed on all four wheels . Mixing tire types is not permitted.
0 Note
• For tec hnical r eas ons, it is no t gene rally possible to use the
whee l rims from other vehicles . ihis can hold true for wheels of the
same ve hicle type.
• I f the spare tire is different from the tires that you have mounted
on y our ve hicle (f or exampl e wi nter t ires or wide p ro fi le tir es), then
use the spa re tire fo r a short per iod of time on ly and d rive with extra
c a re . Rep lace the flat t ire wi th the ti re m atc h ing t he oth ers o n you r
vehic le as soon as possib le .
• If yo u should put diff eren t w heels a nd tires on yo ur vehi cle (e. g.
winter wheels and tires), you must be certa in that the wheels and
t ires a re co mpatibl e w ith the tire press ur e m onit orin g sys te m.
Otherwise the system will regist er a ma lfunction and a fau lt
mes sage wil l be d isp layed . Fo r mo re info rmation, contact yo ur Audi
dea ler .

Tires and wheels 1111
----------------
W For the sake of the environment
Use summer tires when weather conditions permit. They are
quieter, do not wear as quickly and reduce fuel consumption. •
Snow chains
Snow chains may be fitted only to the front wheels, and only to
certain tire sizes. Ask your authorized Audi dealer on which tire
sizes snow chains can be used.
If you are going to use snow chains, then you must install them on
the front wheels at least.
The snow chains must have low-profile links and must not be thicker
than 0.53 inch (13.5 mm), including the lock.
Remove wheel center covers and trim discs before putting snow
chains on your
vehicle => 0. For safety reasons cover caps must
then be fitted over the wheel bolts. These are available from autho­
rized Audi dealers.
& WARNING
Using the wrong snow chains for your vehicle or installing them
incorrectly can increase the risk of loss of control leading to
serious personal injury.
• Snow chains are available in different sizes. Always make sure
to follow the instructions provided by the snow chain manufac­
turer.
• When driving with snow chains never drive faster than the
speed permitted for your specific snow chains.
• Always observe local regulations .
0 Note
• Remove snow chains before driving on roads not covered with
snow to avoid damaging tires and wearing the snow chains down
u n necessarily.
• Snow chains, which come into direct contact with the wheel rim,
can scratch or damage it . Therefore, make sure that the snow chains
are suitably covered.
[ i] Tips
Where snow chains are mandatory on certain roads, this normally
also applies to vehicles with All Wheel Drive. •
Wheel bolts
Wheel bolts must always be tightened to the correct
torque.
The design of wheel bolts is matched to the factory installed rims. If
different rims are fitted, the correct wheel bolts with the right length
and correctly shaped bolt heads must be used. This ensures that
wheels are fitted securely and that the brake system functions
correctly.
In certain circumstances, you may not use wheel bolts from a
different vehicle -even if it is the same
model => page 348.
& WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control, a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque.

Notes on wheel change
P lease read the information => page 305 , "N ew tire s and replacing
t ir es a nd whe els" if you are going to use a spa re tire w hich is
different from the t ires on you r ve h ic le.
Aft er you ch ange a tire:
• Check the tire pressure on the spare immediately after
mounting .
• Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a qualified service station .
• On steel and alloy wheel rims , the wheel bolts are correctly tight­
ened with a torque of 90 ft lb (120 Nm ).
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn while changing a tire , they should be
replaced 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, drive with extra care and at reduced speeds .
& WARNING
• If you are going to equip your vehi cle with tires or rims which
differ from those which were factory installed , then be sure to read
the information
=> page 305 , "New tires and replacing tires and
wheels ".
• Always make sure the damaged wheel or even a flat tire and
the jack and tool kit are properly secured in the luggage compart­
ment and are not loose in the passenger compartment .
• In an accident or sudden maneuver they could fly forward ,
injuring anyone in the vehicle .
• Always store damaged wheel, jack and tools securely in
luggage compartment . Otherwise, in an accident or sudden
