Tires
General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least appreciated and most abused pa rts of a motor
vehicle . Tires are, however, one of the most important parts of a
vehicle , pa rticul arly conside ring the comparat ive ly small patch of
rubber on eac h tire that assures that all-important contact between
you, your veh icle and the road.
Maintai ning t he cor rect tire pressu re, mak ing su re that your veh icle
and i ts tires do not have to carry more weight t han they can safely
hand le, avoid ing damage from road ha za rds and regularly inspecting
tires for damage includ ing cuts, s lashes irregular wea r and ove rall
condi tion a re the mos t important th ings that you can do to help avoid
sudden t ire failure including tread separation and blowouts.
Avoiding damage
If you have to d rive ove r a cur b or sim ilar obstacle, d rive very slowly
and as close as possible at a rig ht angle to the curb .
Always keep chemicals incl ud ing grease, oil, gaso line and brake f luid
o ff t he t ires .
Ins pect the ti res regularly for damage (cu ts, cracks o r blisters, e tc.) .
Remove any foreign bodies embe dded in the treads.
Storing tires
M ark tires w hen yo u remove t hem to indica te t he d ire ct io n of rota
tion . This ensures you to be ab le to mount them correctly when you
re insta ll them.
Whe n removed, t he wheels or tires should be sto red in a cool, dry and
preferably da rk p lace.
Safety first
Store tires in a v ertica l pos it io n if they a re not mount ed on rims, in a
hor izonta l posit ion if they are mounted on r ims.
New tires

Hidden damage
Damage to tires and rims is often not readi ly visible. If yo u notice
unu sual vib ra ti on o r the ve hicle pulls to one side, t his may in dica te
that one of the t ires has been damaged. The tires must be checked
im media tely by an auth oriz ed A ud i d eale r or qual ifie d wor ks hop.
Unidirectional tires
A un id irectional tire can be identified by arrows o n th e sidewall , th at
point in the direct ion the t ire is designed to rotate. You must fo llow

& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control, a collision and serious personal injuries, dri ve with special care for the first 350 miles (560 km).
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately. _..

Cord
means the st rands forming the plies in the tire.
& W ARNING (continued )
• Never mount used tire s on your vehicle if you are not sure of
their "previous hi story ." Old used tires may have been damaged
eventhoughthedamagecannotbeseenthatcanleadtosudden
tire failure and lo ss of vehicle control.
• If you notice unu sual vibration or if the vehicle pull s to one side
when driving, alway s stop as soon as it is safe to do so and check
the wheels and tires for damage. •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle ma nufa cturer
for a tire of a des ignated size t hat has not been driven for more than
a couple of m iles ( kilomete rs) a t low speeds in the t hree ho ur period
before the tire pressure is measured or ad justed.

Incorrect wheel alignment
In correct whee l al ignme nt can ca use excessive tir e wea r, impairing
th e sa fety o f the vehicl e. If t ires show excessive w ear, hav e the w heel
alignment checked by a n authorized A udi dea ler or qualifie d work
shop.
All Wheel Drive
Vehicles wi th quattro® must always have tires of the same size ,
con st ruct ion an d tread type . For details see~
page 194.
& WARNING
Sudden tire failure can lead to los s of control, a cra sh and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• 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 t ire 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
even though the damage cannot be seen that can lead to sudden
tire failu re and loss of vehicle control. •

• Snow chain s are available in different sizes. Always make sure
to follow the instructions provi ded by the snow chain manufac
turer.
• Wh en driving with snow cha in s never drive fa ster than the
speed permitted for your specific snow chains .
• Always observe local regulations.
0 Note
• Remove snow chains before d riving on roads not cove red w it h
snow to avoid damaging t ires and wearing t he snow chains down
unnecessar ily .
• Snow chains, which come into direct contact wi th the wheel rim,
can scratch or damage it . The refore, make s ure that the snow chai ns
are sui tably covered. Chec k the pos it ion o f the snow cha ins afte r
driving a few yards and correct if necessary . Follow the instructions
from t he snow chain man ufacturer when doing so .
[ i] Tips
• Where snow chains are mandatory on certa in roads, this normally
also app lies to ve hicles wi th A ll W hee l Dr ive.
• If snow chains are installed, the tire p ress ures s houl d not be
sto red in the tire pressure moni to ring system (TPMS) . Otherwise the
system could malfunction ~

Wheel bolts
Wheel bolts must al ways be tight ened to the c orrect
torqu e.
The desig n of whee l bolts is matc he d to the fa ct ory in stalled rims. If
different r ims are fitted, the cor rect wheel bo lts wi th t he r igh t length
and correctly s haped bolt hea ds must be used . Thi s ensures that
Safety first
wheels are fitted securely and that the brake system funct ions
cor rectly .
I n certa in circumstances, yo u may not use wheel bo lts from a
different vehicle -even if it is the same mo del.
& WARNING
Improperly tightened or maintained wheel bolts can be come
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 bolt s can turn easily and be properly tightened .
• Never grease or oil the wheel bolts and the th reads in the wheel
hub s. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolt s 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 loo sen and come out when the
vehicle is moving . If the tightening torque is too high , the wheel
bolt s and thread s can be damaged and the wheel can become
loose.
0 Note
T he specified torq ue for the wheel bo lts is 90 ft lb (120 Nm) with a
t o le rance of ± 7,4 ft lb( ± 10 N m). Tor qu e wheel bo lts diagonally.
After cha nging a wheel, the torque must be checked as soon as
pos sible wi th a t orque w rench -prefer ably by an auth oriz e d Aud i
dealer or qualified workshop .•

Lifting the vehicle
Important safety precautions
Be aware of the following hazards before lifting the vehicle with a
workshop hoist or floor jack:
• The vehicle should never be lifted or jacked up from underneath
the engine oil pan, the transmission housing, the front or rear axle
or the body side members. This could lead to serious damage.
• Use lifting equipment with padded contact surfaces to avoid
damage to the underbody or chassis frame.
• Alternatively, cover the contact surfaces on workshop hoist or
floor jack with rubber pads before lifting.
• Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist.
• Before driving over a workshop hoist, ensure that there is suffi
cient clearance between the hoist and low parts of the vehicle.
& WARNING
To reduce the risk of serious injury and vehicle damage:
• Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated
~ fig. 203 and=> fig. 204.
• Failure to lift the vehicle at these points could cause the vehicle
to tilt or fall from a lift if there is a change in vehicle weight distri
bution and balance. This might happen, for example, when heavy
components such as the engine block or transmission are removed.
• When removing such heavy components, anchor vehicle to
hoist or add corresponding weights to maintain the center of
gravity. Otherwise, the vehicle might tilt or slip off the hoist,
causing serious personal injury. •
Lifting with workshop hoist and with floor
jack
The vehicle may only be lifted at the lifting points illus
