&, 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 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

• 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

• 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
