The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are specially matched to the char­ acteristics of the vehicle and can make a major contribution to good
road holding and safe handling when in good condition and prop­
erly inflated =>& .
We recommend that all work on tires and wheels be performed by
an authorized Audi dealer. They are familiar with recommended
procedures and have the necessary special tools and spare parts as
well as the proper facilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about tech ­
nical requirements for installing or changing tires and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together).
Be sure to read and heed the information to the tire pressure moni ­
toring system =>
page 327.
Always buy replacement radial tires that have the same specifica ­
tions as the tires approved for your vehicle by Audi. Replacement
tires must always have the same load rating specification as the original equipment or approved optional tires listed in the table
=> page 317.
Audi -approved specification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road-.,_

& WARN ING (continued )
• All four wheels mu st be fitted with radial tires of the same type,
si ze (rolling cir cumference ) and the same tread pattern. Driving
with different tires redu ces vehicle handling and can le ad to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehi cle -for e xample with winter tires -only use the spare
t ire for a short period of time and drive w ith extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum speed for whi ch the tires
on your vehicle are rated becau se t ires that are driven faster than
their rated speed c an fail suddenly .
• Overload ing tires cause heat build-up , sudden tire failure,
including a blowout and sudden deflation and loss of control .
• Tempe rature grades apply to t ires that are properly inflated and
not over or underinflated.
• Fo r techni cal reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model .
• If you install wheel trim discs on the vehicle wheels , make sure
that the air flow to the brakes is not blo cked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be u sed on vehicles that were equipped
with them at the factory . The vehicle must have a chas sis designed
for run flat tires and a factory -installed tire pressure monitoring
system that indi cates a loss of tire pressure . In corre ct u se of run
flat tires can lead to vehicle damage or accidents . Check with an
authori zed Audi dealer or tire specialist to see if your vehicle can
be equipped w ith run flat tires . If run flat tires are used , they must
be installed on all four wheels . Mi xing tire types is not permitted.
0 Note
• For technical reasons, it is not ge nerally poss ible to use the
whee l rims from other vehicles. This can ho ld t rue for whee ls of the
same ve hic le type.
• I f the s pa re tire is diffe rent from the tires that you have mo unted
o n your veh icle ( for e xample w inter t ires or w ide pro file t ires), the n
use the spare tire for a short period of time on ly and drive with extra
ca re. R ep lace the flat t ire w ith th e ti re m atc hin g the o thers o n your
vehic le as soon as possib le.
• I f you should put different w hee ls and t ires o n you r ve hicle (e.g.
winter wheels and tires), you must be certain that the wheels and
t ires are co mpat ible w ith the tire pressure monit oring syst em.
Otherwise the system will register a ma lfunction and a fau lt
m essage w ill be d isplayed . For more info rmatio n, con tact your Aud i

hub. Remove all dirt from these surfaces before remounting the
wheel. •
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed in the right direction.
Using a spare tire with a tread pattern intended for use
in a specific direction
When using a spare tire with a tread pattern intended for use in a
specific direction, please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire .
• If the spare tire has to be installed in the incorrect direction, use
the spare tire only temporarily since the tire will not be able to
achieve its optimum performance characteristics with regard to
aquaplaning, noise and wear.
• We recommend that you pay particular attention to this fact
during wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible to restore the handling advantages of a
unidirectional tire. •
Notes on wheel changing
Please read the information~ page 325, "New tires and replacing
tires and wheels " if you are going to use a spare tire which is
different from the tires on your vehicle.
After you change a tire:
• Check the tire pressure on the spare immediately after installa­
tion . •
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 Nml.
• If you notice 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 vehicle with tires or rims which
differ from those which were factory installed, then be sure to read
the information
