Snow chains
Snow chains may be fitted on ly to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on whic h tire sizes
snow chains can be used.
I f you are going to use snow chains , then you
must install them on the front wheels at
l east.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch (10 ,5 mm), including the lock .
Remove wheel center covers and tr im discs
before putting snow cha ins on your vehicle
c:;, Q) _ For safety reasons cover caps must the n
be fitted over the whee l bolts. These are ava il­
ab le from authorized Audi dea lers.
A WARNING
Using the wrong snow chains for yo ur vehi ­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
ser ious personal inj ury.
- Snow chains are ava ilable in different
sizes. Always make sure to follow the in­
struct ions provided by the snow chain
manufacturer .
- When driving w ith snow chains never
dr ive faster than the speed permitted for
your specific snow cha ins.
- Always observe local regulat ions .
([) Note
-Remove snow cha ins before driving on
roads not covered with snow to avoid
damaging t ires and wear ing the snow
chains down unnecessar ily.
- Snow chains, wh ich come into d irect con­
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitab ly covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sa ry. Follow the i nstructions from the
snow cha in manufacture r when doing so.
- If the Adaptive Air Suspension* should
malfunction, do no t mo unt or use snow chains because the vehicle will be ex
­
treme ly low. If you do drive with snow
chains on while the vehicle is at this lev ­
el, the snow cha ins might severely dam­
age the whee lhouse and other parts of
the vehicle .
(D Tips
Where snow chains are mandatory on cer­
tain roads, th is normally a lso applies to
vehicles with all-wheel drive.
Wheel bolts
Wheel bol ts mus t alway s be tightened to the
correc t torque.
The design of wheel bolts is matched to the
factory installed rims . If different r ims are fit­
ted, the correct wheel bol ts with the righ t
length and correct ly shaped bolt heads must
be used . T his ensures that wheels are fitted
securely and that the b rake system functions
co rrect ly.
In certa in circumstances, you may not use
wheel bolts from a different veh icle -even if it
is the same model
c:;, page 275 .
A WARNING
Imp rope rly t ightened or ma inta ined wheel
bo lts can become loose c ausing loss of
control, a col lision and serio us pe rsonal i n­
jury .
- Always keep the wheel bo lts and the
threads in the wheel hubs clean so the
wheel bo lts can turn easily and be prop­
erly tightened.
- Never g rease or oil the wheel bolts and
the threads in t he wheel hubs . They can
become loose while driv ing if greased or
oiled, even if t ightened to the specified
torque.
- On ly use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the whee l bolts to reduce the

risk of a wheel loss . If the tightening tor­
que 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 whee l bolts and threads
can be damaged and the wheel can be­
c ome loose.
(D Note
The spec ified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of ± 7,4
ft lb(± 10 Nm) . Torque wheel bo lts d iago­
na lly . After chang ing a wheel, the torque
m ust be che cked as soon as possib le w it h a
t orque wrenc h -preferab ly by an a utho r­
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipp ed with low aspect
ratio t ires. These t ires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
and handling unde r a va riety of driving condi­
tions. Ask your a uthorized Aud i dea le r fo r
mo re deta ils.
T he low aspect ratio of these tires is indicated
by a nume ral of
55 or less in the tire's size
des ignation . T he numeral represents the rat io
of the ti re's sidewall height in relat io n t o its
tread wid th expressed in per cen tage . C o nven­
tional t ires have a height/width ra tio of 60 or
mo re.
Th e performan ce of low -aspe ct-ratio tir es is
parti cularl y se nsitive to improper inflation
pressure . It is therefore impor tant that low
a s pect ratio tire s are inflated to the specified
pressure and that the inflation pre ssure is
regularly checked and maintained. Ti re pres­
sures should be checked at least once a
month and always before a long trip
c::> page 234, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
eas ily by impact with potho les, curbs, gu llies
Tire s an d wheel s 245
or r idges on the road, partic ularly if the tire is
u nderinflated.
In orde r to minimize t he occ urren ce of impact
dam age to the tires o f your vehi cle, we recom ­
mend that you observe the following p reca u­
tions:
- Always ma int ain re commended inflation
pressu res . Check your tire pressu re eve ry
2,000 miles ( 3,000 km) and add air if neces ­
sary.
- Dr ive ca re fu lly on roads with potholes, deep
gullies o r ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires .
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest
au thor ized Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires every 2,000 m iles (3,000
km) for damage and wear. Damage is no t al­
ways easy to see . Damage can lead to loss of
air a nd under inflat ion, which could eventu­
ally cause tire failure .
If you believe that a
t ire may have been damaged, rep lace the
t ire as soon as possib le.
- These tires may wear more quickly tha n oth­
ers.
- Please also remember that, while these tires
de live r respon sive handling, they may ride
less comfo rtably and m ake more noise tha n
other choi ces .
Reduced performance in winter /cold
season conditions
A ll ti res are designed for cer ta in p urposes.
T he low aspect ratio, ult ra h igh performance
tires originally installed on your vehicle are i n­
tended for maxim um dry and wet road per­
f ormance and handling. They are not suitable
for cold , snowy or icy weather condi tions. If
you drive under those circumstances, you
shou ld equ ip your vehicle w it h all -season or
winter tires, which offer bette r traction under
those conditions. We suggest you use the rec­
ommended snow o r all-season t ires specified
f o r yo ur vehicle , or t hei r equivalent . .,..

(D Note
When remov ing or installing the wheel,
the rim cou ld hit the brake rotor and dam­
age the rotor. Work carefu lly and have a
second person help you.
(D Tips
Never use the hexagonal socket in the han­
d le of the screwdriver to loosen or tighten
the wheel bolts.
- Pull the reversible blade from the screw­
driver before you use the hexagonal
socket in the handle to turn the wheel
bolts.
- When mounting tires w ith
unidirectional
tread design
make sure the tread pat­
tern is pointed the right way
c:>page25 9.
-The wheel bolts should be clean and easy
to turn . Check for dirt and corrosion on
the mating surfaces of both the wheel
and the hub. Remove all dirt from these
surfaces before remounting the wheel.

Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a replacement tire with a tre ad
patte rn intend ed for us e in a specific
directi on
When us ing a replacement t ire with a tread
pattern intended for use in a specific direc­
tion, please note the fo llowing :
- T he direction of rotation is marked by an ar­
row on the side of the tire .
-If the replacement tire has to be installed in
t h e incorrect d irection, use the rep lacement
t ire only temporarily since the t ire will not
be able to achieve i ts optimum performance
characteristics with regard to aquap laning,
noise and wear .
- We recommend that you pay particular at­
tention to this fact during wet weather and
that you adjust your speed to match road conditions .
- Replace the flat tire with a new one and
have it installed on you r veh icle as soon as
poss ible to restore the handling advantages
of a unid irect ional tire.
