252 Tire s and wheel s
Where snow chains are mandatory oncer
tain roads, this normally also applies to ve
hicles with all-wheel drive.
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 rims . If different rims are fit
ted, the correct wheel bolts with the r ight
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r=> page 280.
A WARNING
Imprope rly tightened o r maintained wheel
bolts can becom e loose ca using loss of
c ont ro l, a co llision and serious persona l in
Jury .
- Always keep the w heel bolts an d the
threads in the wheel hubs clean so the
w heel bolts can turn easily and be p rop
er ly tigh tened .
- N ever grease or oil the wheel bo lt s an d
the threads in the w heel hubs. They can
become loose while d riving if greased or
oi led, even if tightened to the specified
torq ue.
- Only use wheel bolts that belong to the
rim being installed.
- N ever use different whee ls bolts on your
vehicle.
- Alw ays maintain the co rrec t tighten ing
torq ue fo r th e wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor
que of the wheel bo lts is too low, they
can loosen and come out w hen the veh i
cle is moving. If the tighteni ng torque is
too high, the whee l bolts and threads can be damaged and the whee
l can be
come loose.
@ 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) . Torque whee l bolts diago
nally. After changing a whee l, the torque
must be checked as soon as possible with a
torque w rench -preferably by an author
i zed Audi dealer or qualified workshop .
Low aspect ratio tires
Your A udi is facto ry-eq uipped w it h low aspect
ra tio tires. These tires have been tho roughly
tested and been se lected specific ally fo r your
model fo r their superb perfo rmance, road fee l
and hand ling under a variety of d riving condi
t ions . Ask your author ized A udi dealer for
more details.
T he low aspect ratio of these tires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The n umera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage. Conven
t iona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-aspect -ratio tires is
particularly sens iti ve to imp roper inflation
pressure. It is therefore important that low
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure i s
regularly ch ecked and maintain ed. Tire pre s·
sure s should be checked at lea st once a
month and always before a long trip
r=> page 241, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ra tio tires can be d amage d more
easily by impact w it h potholes, curbs, g ull ies
or ridges on t he road, particularly if the tire is
u nd eri nflated.
