Wheel bolts
Wheel bolts mus t alwa ys be tighte ned to t he correct
to rq ue .
The design of wheel bo lts is matched to the factory installed rims. If
di fferent r ims are fitted , th e cor rect whe el bo lts wi th the rig ht l ength
and c orrec tly shaped bolt heads must be used . This ens ures that
w he els a re fitted se cur ely and th at the bra ke syste m functi ons
correctl y.
In cer ta in c ircums tances, yo u ma y not use w hee l bolts fr om a
differ ent vehicle - even if it is the same model~
page 384 .
& 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 being 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 s pecified torque for the wheel bolts is 90 ft lb ( 120 N m) with a
to lerance o f± 7,4 ft lb(± 1 0 Nm). Torque whee l bolt s diago nally.
After chang ing a whee l, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi

Low aspect ratio tires
You r A ud i is fac tory-eq uippe d w ith low aspect ra tio tire s. T hese tire s
have been thorough ly t ested and b een se lected specifica lly for your
mod el for thei r su p erb pe rf or manc e, r oad f eel an d ha nd ling under
a variety of driving con ditions . As k your authorized Audi d ealer for
m ore de ta ils.
The low aspect rat io o f th ese t ires is indicated by a numer al of 55 or
less in the t ire's size designation. The numeral rep resents the ratio
o f t he t ire's s idewa ll he ig ht in rel ati on to it s tread w idt h ex pressed
in percentage . Conventiona l tires have a height/width ratio of 60 or
mo re.
The performan ce of low -aspe ct-ratio tires is particularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflat ion pressure is regularly checked and ma intained. Tire pres­
sures should be checked at least once a month and always before a
long trip~
page 333, "Checking tire pressure" .
What you can do to avoid tire and rim damage L ow aspect ratio tires can be damaged mo re easily by impact with
po tho les, cu rbs, gull ies o r rid ges o n th e road, particular ly if the t ire
is underinf lated .
I n or der to mini mize th e occurrence of i mpac t da mag e to t he tires
of your vehicle, we recommend that you observe the fol lowing
pr ecaut ions :
• Always ma intain recom mended inflatio n pr essu res . C heck you r
ti re p ressu re eve ry 2,000 mi les (3,000 k m) and add a ir if neces sary .
• D rive carefully on roads with potho les, deep gullies or ridges.
T he impact from d riving th rough or ove r such obstac les can
da mage y our tires. I mpact with a cu rb m ay a lso cause damage to

flat tire/wheel in its storage area properly and tighten the knurled
retaining screw securely.
[ i J Tips
Before changing the wheel, you must activate the jacking mode, so
that the automatic controls for the Adaptive Air Suspension do not
make it more difficult to lift the vehicle with the jack =>
page 791. •

A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
- Check the
tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible , have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct tightening torque is 90 ft lb (120 Nm) .
- Have the flat tire
replaced as soon as possible.
[ i J Tips
• 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. .,_
