254 Tires and wheels
-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 histo­
ry." Old used tires may have
been damaged even though
the damage cannot be seen
that can lead to sudden tire
fa ilure and loss of vehicle
control. New tires and replacing
tires and wheels
New tires and wheels have to
be broken in.

256 Tires and wheels
the Audi models covered by
your Owner's Literature.
The tire pressure label located
on driver's side B-pillar
(¢ page 240, fig . 169) lists the
specifications of the original
equipment tires installed on
your vehicle at the time it was
manufactured .
Federal law requires tire manu­
facturers to place standardized
information on the sidewall of
all tires
¢ fig. 172. This infor­
mation identifies and describes
the fundamental characteris­
tics, the quality grade of the
tire and also provides a tire identification number for safety
standard certification and in
case of a recall.
Tire specifications
Knowledge of tire specifications
makes it easier to choose the
correct tires . Radial tires have
the tire specifications marked
on the sidewall, for example:
255/40 R 19 100 H XL
This contains the following in­
formation :
P Indicates the tire is for pas­
senger cars (where applica­
ble)
255 Nominal tire width in mm
of the tire from sidewall
edge to sidewall edge. In
general, the larger the num­
ber, the wider the tire
40 Height/width ratio in per­
cent (aspect ratio)
R Tire construction: Radial
19 Rim diameter code (in in-
ches)
100 Load rating code
H Speed rating letter code
XL (or "xl", "EXTRA LOAD" or
"RF") Indicates that the tire
is a "Reinforced" or an "Extra
Load" tire
M+S (or "M/5 ") Indicates that
the tire has some mud and
snow capability
The tires could also have the in­
formation of direction of rota­
tion
¢ page 234.
Tire manufacturing date
The manufacturing date is also
indicated on the tire sidewall
(possibly only on the
inner side
of the wheel) : .,..

In certain circumstances, you may not use
wheel bo lts from a different vehicle -
even if it
i s the same mode l
Q page 291.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
control, a collision and ser ious personal in­
jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose w hile d riving if greased or
o iled,
even if tightened to the spec ified
torq ue.
- Only use wheel bo lts that belong to the
rim being ins talled.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the correct tightening
torque fo r the wheel bolts to reduce the
risk of a wheel loss. If the tigh teni ng 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 ca n be­
come loose .
(D Note
The specified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of
± 7,4 ft lb(± 10 Nm). Torque whee l bolts
diagonally. After changing a wheel, the
torque must be checked as soon as possi­
b le with a torque wrench -prefe rably by an
author ized Audi dealer or qualified wo rk­
shop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires . These tires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
Tire s an d wheel s 263
and handling under a variety o f driving condi ­
tions. Ask your authorized A udi dealer for
more details .
T he low aspec t ratio of these tires is ind icate d
by a numera l of
55 or le ss in the tire's size
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage.
Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-a spect-ratio tire s is
particularl y sens it iv e to improper inflation
pressure. It is therefore important that low
a spect ratio tir es are inflated to the specified
pre ssure and that the inflation pr essure i s
regularly checked and ma intain ed . Tire pr es­
s ure s should be checked at lea st on ce a
month and alway s bef ore a long trip
~ page 245 , Checking tire pressure .
A Word about Low Aspect Ratio and High
Performance Ti res
Hig h pe rformance tires are des igned for bet­
ter performance and handling in warm cli­
mates. When driving in cold, snowy or icy
weather, you sho uld equ ip your vehicle w it h
four all-season or winter tires, which
offer
better traction under those condit ions. We
suggest you use the Audi recommended win­
te r or a ll-season tires specified for you r Audi.
High performance tires a lso have a lower as ­
pect ratio that aids performance and han­
dling . Driving over rough or damaged road
surfaces, as well as debr is, cu rbs and other
obstacles can cause serious damage to
whee ls, tires, vehicle body, and suspens ion
parts . B e carefu l to avo id road hazards and re­
du ce your speed , espec ia lly if your vehicle is
equipped wi th low prof ile tires .
Please a lso remember when making your se­
lection that, wh ile these tires deliver respon­
s ive handling, t hey m ay ride less comfo rtably
and make more noise than o thers . Finally,
these tires may wear more quickly than other
c h oices.

lifting point on the sill for the vehicle jack.
.. Vehicles with a sill : Note the position of the
sill when positioning the vehicle jack
r::!) fig. 183.
.. Place the vehicle jack (vehicle tool kit) on a
firm surface. Use a flat , stable support if
necessary . On a slippery surface such as tile,
you should use a non-slip pad (such as a rub ­
ber mat)

.. Align the jack so that its arm @ Q
fig. 183
engages in the designated lifting point in the door sill and
the movable base @ lies
flat on the ground. The base @ must be
ver­
tical
under the lifting point@ .
.. Wind the jack up further until the flat tire
comes off the ground Q

Position the vehicle jack only under the desig­
nated lifting points on the sill
Qfig . 182.
There is exactly one location for each wheel.
The jack must not be positioned at any other location Q
,&q(j) _
An unstable surface under the jack can cause
the vehicle to slip off the jack. Always provide a firm base for the jack on the ground . If nec­
essary place a sturdy board or similar support
under the jack . On
hard, slippery surfaces
(such as tiles) use a rubber mat or similar to
prevent the jack from slipping Q
,&.
_& WARNING
- You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- Position the vehicle jack only at the
designated lifting points and align the
jack. Otherwise, the vehicle jack could
slip and cause an injury if it does not
have sufficient hold on the vehicle .
- A soft or unstable surface under the
jack may cause the vehicle to slip off
the jack . Always provide a firm base for
the jack on the ground. If necessary,
use a sturdy board under the jack.
- On hard, slippery surface (such as tiles)
use a rubber mat or similar to prevent
the jack from slipping.
- Only raise your vehicle with the vehicle
jack provided by the factory. If you use
a vehicle jack for another vehicle, your
vehicle can slide and cause injury.
- Changes in temperature or load can af­
fect the height of the vehicle .
- Never start the engine when the vehi­
cle is raised, which could cause an acci-
dent.
