Tread wear
The tread wear grade is a compa ra tive ra ting based on the wear rate
of the tire when tested unde r co ntrolled conditions on a specified
government test co urse.
For examp le, a tire g rade d 150 would wea r o ne and one half (1 1/2)
times as well on the government course as a tire graded 100.
Th e relat ive performance o f tires depends upon t he ac tual con ditions
o f their use, however , and may de pa rt s ig ni ficantly from the norm
due to variations in driv ing ha bits, service prac tices an d differences in
roa d characterist ics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, Band C. Those
grades represent the tire's ab ility to s to p on wet pavemen t as
meas ured under controlled condit ions o n spec ified governme nt test
s u rfaces of asphalt and conc rete. A tire mar ked C may have poo r trac­
ti on perfo rma nce => & .
Temperature
The temperature grades are A (t he h ighest), B, a nd C, rep resenting
the t ire's resistance to the gene rat ion of heat and its ab ility to dissi­
pate hea t when test ed unde r co ntro lled condi tions o n a spe cifi ed
indoor laboratory test wheel.
S ust ain ed high te m peratu re can cause t he mate rial of the tire to
degenerate and reduce tire life, and excessive temperatu re ca n lead
t o sudden tire fail ur e=> & .
Th e g rade C cor responds to a leve l of performance which all
passenger car tires m ust meet under the Fede ral Motor Vehicle
Safety Standa rd No. 109. G rades Band A rep resent higher levels of
per formance on the labo ratory test whee l than the minimum
req uired by law .
Safety first
& WARNING
The traction grade assigned to this tire is based on straight -ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinfla­
tion, or e xcessive loading, either separately or in combination, can
c ause heat buildup and po ssible tire failure .•
Winter tires
W inter tires can improve vehicl e handling on snow and
ic e. A t temper atures belo w 45 °F (7 °C) we recommen d
ch angin g to win ter tires .
In some heavy snow areas , loca l gover nments may requ ire true
wi nte r o r "snow" t ires, those with very deep ly c ut trea d. These tires
should only be use d in pairs and be i nstalled on all fo ur w heels . Mak e
sure you purchase snow tires that are the same size a nd constr uction
t ype as the ot her tir es o n your ve hicle.
If your veh icle is eq uipped with all-wheel drive*, th is will improve
t raction during w inte r drivin g, eve n with t he standard tires . However,
we st rongly recomme nd that you a lways equi p all four w hee ls on your
vehicle with correctly fitte d winter t ires or a ll-season ti res, w hen
wi nter road conditions a re expe cte d. Thi s also improves the vehicle 's
bra king pe rformance and re duces stop ping distances.
S u mme r tir es pro vide less g rip on ice and snow .
Winter tires (snow tires) must always be fi tted on all fo ur whee ls .
Ask yo ur autho rized Audi deale r or qu alified wor kshop for permitted
winter tire sizes . Use only ra dial w inte r tir es. ..

Winter tires lose their effectiveness when the tread is worn down to
a dep th o f 0. 15 7 inch (4 m m).
Only drive w it h w inte r tir es under w inte r co nd it io ns. S u mmer t ires
hand le better w hen there is no s now or ice on t he roads a nd the
t em pe ra ture i s above 4 5
°F (7 ° ( ).
If you have a flat tire, see notes on spare wheel~ page 257.
Please always remember that winter tires may have a lower speed
rating than t he t ires originally installed on yo ur ve hicle at the time it
was ma nufact ured . Please see~
page 259, "Speed rat ing ( letter
c ode)" fo r a listing of the speed rating le tte r codes a nd t he maximu m
speed at which the tires can be dr ive n.
Th e spee d rat ing le tt er code( ~
page 259 ) is on the side w all of the
t ire~
page 257 .
& WARNING
Winter tires have ma ximum speed limits that may be lower than
your vehicle's maximum speed. Always know the maximum speed
before driving off. Never drive faster than the speed perm itted fo r
your specific winter tires . This will cause damage to the tire s
leading to an accident and serious personal injury to you and your
passengers.
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were des igned can cause ti re failure includ ing a
blowout and sudden deflation, lo ss of control, crashes and serious
personal injuries . Have worn or damaged tires replaced immedi­
ately.
• Winter t ires have maximum speed rat ing that may be lower
than your vehicle's maximum speed .
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated.
& WARNING
Always adjust your driving to the road and traffic conditions.
Never let the good acceleration of the winter tires and all-wheel
drive tempt you into taking extra risks. Always remember :
• When braking , an all-wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions.
Use s ummer tires when weather co ndit io ns permit. They are qu ieter,
do not wear as quickly and reduce fuel consum ption .•
Snow chains
Snow chains may be fit te d on ly to the fr ont w heels, and only to
certain t ire sizes . Ask yo ur aut horized Audi dealer on which tire sizes
snow chains can be used .
If you are go ing to use snow c ha ins, then you must insta ll th em on t he
front wheels at least .
Th e sn ow chain s mus t have low-pr ofile li nks and m ust no t be th icker
than 0 .53 inc h (13.5 mm), including the lock.
R emove wheel cente r covers an d trim discs before putti ng snow
chains on your vehicle~
0. For safety reaso ns cove r caps m ust the n
be fitted over the whee l bo lts. These are availab le from a utho rized
Audi dealers.
& WARNING
Using the wrong snow chains for your veh icle or installing them
incorrectly can incre ase the risk of loss of control leading to
serious personal injury .

& WARNING (co ntinued )
• 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 .•
