Wheel balancing
The w heels on new ve hicl es a re bala nced. However, v ario us sit uatio ns
dur ing everyday driving can cause them to become unba lanced,
re su lt ing in vibra tions yo u can usually fee l throug h the stee rin g
w hee l.
Unbalanced whee ls mus t be rebalanced to avoid excessive wear on
s t eer ing, suspension and t ir e s. A wheel must also b e rebalanced
w hen a new tire is installed.
Safety first
Incorrect wheel alignment
Incorrec t wheel a lignment can c ause excessive t ire wear, im pair ing
t he sa fety o f the ve hicle . If t ires s how exc essive wear, hav e the wheel
alignment checked by an author ized A udi dealer o r qualifie d wo rk ­
shop.
All Wheel Drive
Vehicles with quattro ® must a lways have tires of the same s ize,
constr uctio n an d trea d type . For details see ;:::,
page 258 .
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear ind icators .
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil , gasoline and brake fluid away from tires.
• 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

tire failure and loss of vehicle control. •

Wheel bolts
Wheel bolts must al ways be tightened to the correct
torque .
The design of wheel bolts is matched to the factory installed rims. If
different r ims a re fitted, the cor rect wheel bolts with the r ig ht leng th
and correctly shaped bolt heads must be used. Th is ensures that
w heels are fitted secure ly and that t he br ake system func tion s
correctly .
In certain circ umstances, you may not use whee l bolts from a
different veh icle -even if it is the same model~
page 368.
&_ WARNING
Improperly tightened or maintained wheel bolts can become
loose causing lo ss of control , a c ollision and seriou s personal
injury .
• Always keep the wheel bol ts and the thread s in the wheel hub s
clean so the wheel bolts can turn easily and be properly t ighten ed .
• Never gr ease or oil the wheel bolt s and the threads in the wh eel
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 .
• Alway s maintain the correct tightening torque for the wheel
bolt s to reduce the risk of a whee l los s. 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 i s too h igh, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The spe cifie d torq ue for the whee l bolts is 120 ft lb (160 Nm) wi th a
tolerance of ± 7,4 ft lb( ± 10 Nm). Torque whee l bolts diagona lly. After changing a wheel, the torq
ue m ust be checked as soo n as
possible wi th a t orqu e w rench -prefer ably by an auth o riz ed Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
h ave bee n thorou ghly teste d and been se lec ted spe cifically fo r yo ur
model for their superb performance, road feel and hand ling u nder a
var iety of dr iving con ditions . Ask your authorized A udi dea le r for
more deta ils.
The low aspect ratio of these t ires is ind icated by a n umera l of
55 or
le ss
in t he tire 's s ize designation . T he numera l rep resents the ratio o f
the tire's sidewall he ight in relat ion to its tread width exp ressed in
pe rcen tage . Co nven tional ti res have a heig ht/w idth r atio o f 60 o r
more.
The performance of low-aspect-ratio tires i s particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pre ssure is regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always before a
long trip~
page 320, "Che cking t ire press ure".
What you can do to avoid tire and rim damage
Low aspe ct ratio tires ca n be damaged more eas ily by imp act wi th
potholes, curbs, gul lies or ridges on the road, part icu lar ly if the tire is
unde rinfl ated.
I n order to minimize the occu rrence of impact damage to the tires of
your vehicle, we recommend that yo u observe the follow ing p recau ­
tions:
• Always ma inta in recommen ded inflation p ressures. Check your
t ire press ure every 2,000 m iles (3,00 0 km) a nd a dd air i f ne cess ary.
• Drive ca ref ully on roads with potho les, dee p gullies or ridges. The
i m pact from d riving t hrough or over such obsta cles can damage you r
tires. Impact w it h a c urb may also cause damage to your tires . .,_
