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.

&, WARNING (continued )
• Only u se wheel bolts that belong to the rim being installed.
• Never use different wheels bolt s on your vehi cle .
• Alway s maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel los s.
If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehi cle 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 torque for the wheel bolts is 90 ft lb (12 0 Nm) with a
tolerance of± 7,4 ft lb(± 10 Nm). Torque whee l bolts diagonally.
After changing a wheel, the torque must be c hecked as soon as
possible with a torque wrench -preferably by an authorized Audi
d ea ler or qua lifi ed works hop.•
Low aspect ratio tires
Your Aud i is factory -equipped with low aspect ratio tires . T hese tires
have been thorough ly tested and been selected specifical ly for your
mod el for t he ir superb perf or mance, r oad feel and ha ndling u nder
a variety of driving conditions . Ask your authorized Audi dealer for
mo re deta ils.
The low aspect ratio of these tires is indicated by a numeral of
55 or
less
i n the ti re's size designatio n. The numeral rep resents the ra tio
of the t ire's sidewa ll height in relation to its tread width expressed
in percentage . Conventiona l tires have a height/width ratio of 60 or
m ore.
The performan ce of low -aspe ct-ratio tires is part icularly sensitive to
improper inflation pressure . It is therefore important that low
aspe ct ratio tires are inflated to the specified pressure and that the
inflation pressure i s regularly checked and maintained. Tire pres- sures should be checked at least once a month and always before a
long
trip => page 299, "C heck ing tire pre ssure" .
What you can do to avoid tire and rim damage
Low as pect r ati o ti res can be da maged more easi ly by impact w ith
potho les, curbs, gullies or ridges on the road, particularly if the tire
i s u nde rinfl ated.
I n order to min imize the occurrence of impact damage to the t ires
of your vehic le, we recommend that you observe the fo llowing
precautions :
• Always maintain recommended inflation pressures . Check your
t ire pr essu re every 2,000 miles (3,000 k m) a nd add air if necessary .
• Drive careful ly on roads with potholes, deep gu llies or ridges.
T he im pac t from driving t hroug h or ov er suc h ob stacl es ca n
damage your tires. Impact with a curb may also cause damage to
yo ur tir es .
• After any impact, immediately inspect your tires or have them
inspec te d by the neares t au thori ze d Aud i dealer. Replac e a
damaged tire as soon as possible.
• I nspect you r ti res eve ry 2,0 00 m iles (3,000 km) for damage and
wear. Damage is not always easy to see. Damage can lead to loss of
a ir a nd und eri nfl ation, whic h cou ld eve ntual ly ca use tire fa ilur e. If
you be lieve that a tire may have been damaged, rep lace the tire as
s o on as p ossi ble.
• T hese tires may wear more quickly than others .
• P lease a lso remember that, whi le these tires de liver respons iv e
handling, they may ride less comfortably and make more noise t han
other choices.
