A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inter t ires. This will cause damage to the
tires leading to an accident and serious
pe rsonal inj ury to you and your passen­
gers .
A WARNING
= ~
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fai lure in­
cluding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
rep laced immed iate ly .
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
w hich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your d riving to the road and
traffic conditions. Neve r let the good ac­
celeration of the wi nte r t ir es and all-whee l
dr ive temp t you in to taking extr a ris ks . A l­
ways remember :
- Whe n bra king , a n a ll-wheel d rive vehicle
hand les in the same way as a front drive
vehicle.
- Drive caref ully and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
{® For the sa ke of the env ironment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be f itted only to the front
whee ls, and only to certain tire sizes . Ask your
autho rized Aud i dealer on which tire sizes
snow c hains ca n be used.
If you are go ing to use snow chains, then you
must install them on the front whee ls at
least.
The snow chains must have low-prof ile links
and must not be t hicker than 0.53 inch
(13.5 mm), includ ing the lock .
Remove whee l center covers and trim discs
before putt ing snow cha ins on your vehicle
c::> Q) . For safety reasons cover caps must then
be fitted over the wheel bolts . These are ava il ­
able from autho rized Aud i dealers .
A WARNING
Using the wrong snow chai ns for your veh i­
cle o r ins ta ll ing them in correct ly can in­
crease the risk o f loss of cont ro l leading to
se rious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the i n­
structions provided by the snow chain manufacturer .
- When driving with snow cha ins never
d rive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations .
(D Note
-Remove snow chain s before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessa rily.
- Snow chains, which come in to direc t con­
tact with the whee l rim, can scratch or
damage it . Therefore , make sure that the
1J1-

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 245.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile d riving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 213
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 202, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
