ture. For example, the numbers 2209 mean that the tire was
produced in the 22th week of 2009. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades => page 249.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system*
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans­
mits this information to the tire pressure monitoring system *. If you
are going to replace the wheel rims on your vehicle, make sure the
new rims also have these sensors . The sensors must be compatible
with the tire pressure monitoring system * on your vehicle.
If the sensors are to be installed on different rims , the seal, washer ,
and valve cap for each sensor must be replaced.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system* will not work properly.
In this case, the tire pressure moni­
toring system * would not be able to monitor the tire pressure or
warn you if it is necessary .
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho­
rized Audi dealer to replace lost valve stem caps.
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni­
toring system*, and is not recommended (cord material information
in molded on the tire sidewall) .
Always check your tire pressure monitoring system* indicator after
replacing one or more tires on your vehicle. If the tire pressure
monitoring system* indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring sys tem* , or some component o f the
tire pressure monitoring system* may be damaged.
& 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 use 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 emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle 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. .,_

& 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 spec ific snow chains.
• Always observe local regulations.
0 Note
• Remove s now c hains befo re driv ing on roads no t cove re d w it h
snow to avoid damag ing tires and wearing the snow chains down
un nece ss aril y.
• Snow chains, whic h come into direct contact with the wheel rim,
can scratch or da mag e it. There fo re , m ake sure t hat th e s now ch ai ns

Wheel bolts
W heel bo lts mu st a lways be ti ghte ned to t he corr ect
t o rq ue .
The design of wheel bolts is matched to the facto ry instal led rims . If
diff eren t rim s are fitt ed, t he cor rect w heel bol ts with the r ig ht le ngth
and correctly shaped bolt heads must be used. This ensures that
w hee ls a re fitted securely and t hat t he brake sys te m funct io ns
correctly.
In cer tain ci rc u ms tances, yo u may no t use whee l b olt s fro m a
different vehicle -even if it is the same model~
page 295.
& 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.
• Only use wheel bolts that belong to the rim be ing installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss .
If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving. If the tightening torque is too high, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The specified torq ue for the wheel bolts is 9 0 ft lb (120 Nm) with a
t o lerance of± 7,4 f t lb (± 10 N m). To rque w hee l bo lt s d ia g ona lly .
After chang ing a wheel, the torque must be checked as soon as

After 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 .
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 90 ft lb (120 Nm l.
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn , then 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 .
