288 Tire s and whee ls
- All four wheels must be fitted with radia l
t ires of the same type, size (rolling c ir
cumference) and the same tread pattern.
Driv ing with different tires reduces veh i
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
t ires that are mounted on the veh icle -
for example with winter tires - on ly use
the spare tire for a short period of time
and dr ive with extra care. Refit the no r
ma l road whee l as soon as safely possi
ble.
- Never drive faster than the maxim um
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
sudden ly.
- Overloading ti res cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are properly inflated and not over or un
derinflated.
- For technical reasons it is not a lways
poss ible to use wheels from other vehi
cles -in some cases not even whee ls
from the same vehicle model.
- If you install wheel tr im discs on the ve
hicle whee ls, make sure that the air flow
to the brakes is not blocked . Reduced air
flow to the brakes can them to overheat,
increasing stopping d istances and caus
ing a collision.
- Run flat t ires may on ly be used on vehi
cles that were equipped with them a t the
facto ry. The vehicle mus t have a chassis
desig ned for run flat tires. Incorrect use
of run flat tires can lead to vehicle dam
age or accidents. Check with an a uthor
ized Audi dea ler or tire specialist to see if
your vehicle can be equ ipped w ith run
flat tires. If run f lat tires are used, they
must be installed on all four wheels. M ix
ing t ire types is not permitted. (D Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth
er veh icles. T his can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is different from the tires that you have mounted on your ve
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire w it h the
tire mat ching the othe rs on your vehicle
as soon as possib le.
- Never d rive without the valve stem cap.
The va lves cou ld get damaged.
@ For the sake of the environment
D ispose of o ld tires in accordance w ith the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B (
- Temperature ABC
Quality grades can be found where applicable
on the t ire s ide wall between tread shoulder
and maximum section width
¢ page 285,
fig. 241 .
For e xample: Tread wear 2 00 , Traction AA ,
Temperature A .
All passenger car tires must conform to Feder
al Safety Requirements in addition to these
grades .
Tread w ear
The tread wear g rade is a comparative rating
based on the wear rate of the tire when tested
u nder contro lled conditions on a specified
government test course.
For example, a tire graded 1S0 wo uld wear
one and one ha lf (11/2) times as well on the
government course as a tire graded 100.

driving a few yards and correct if neces
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains beca use the vehicle will be ex
tremely low. If you do drive with snow
chains on while the vehicle is at this lev el, the snow chains might severe ly dam
age the wheelhouse and other parts of
the veh icle.
(0 Tips
W here snow cha ins 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 installed r ims. If different rims are fit
ted, the cor rect wheel bolts wit h the right
lengt h and correctly s haped bolt heads must
be used. This ens ures t hat w heels a re fitted
secure ly an d that the brake system f unctions
correctly.
I n ce rtain circumstances, you may not use
wheel bo lts from a d ifferent vehicle -even if it
is the s ame mode l~
page 3 21.
& WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
cont ro l, a co llision and serious persona l in
jury.
- Always keep the w heel 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 driving if greased or
o iled, even if tig hte ned to the specified
torq ue.
Tire s an d wheel s 2 91
-On ly use whee l bolts that be long 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 t he
risk o f a wheel loss. If the tightening tor
que of t he wheel bolts is too low, they
can loosen and come out when t he vehi
cle is mov ing.
If the tig hte ning torque 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
120
ft l b ( 160 Nm) with a to le rance of
± 7, 4
ft lb( ± 10 Nm). Torque w heel bo lts
d iagon ally . After changi ng a w heel, the
torque m ust be chec ke d as soon as poss i
b le with a to rque wrench -preferab ly by an
a uthorized Audi dea ler or q ua lified work
shop .
Low aspect ratio tires
Your Audi is factory-equ ipped with tow aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb perfo rmance, road feel
and handli ng under a var iety of drivi ng condi
tions. As k your au thori zed A udi dealer for
more de tails.
The low asp ect ratio of these tires is ind icated
by a nu mera l of
55 or l ess in the tire's s ize
designation. The n ume ra l rep resen ts the ra tio
of the tire's sidew all height in rel ation to its
tread width exp ressed in percentage . Conven
tiona l tires have a he ight/width ratio of 60 or
more.
The performance of low-aspect-ratio tire s is
particularly sensitive to improper inflation
pre ssure. It is therefore important th at low
aspect ratio tires are inflated to the specified pressure and that the inflation pressure is
regularly checked and mainta ined. Tire pres-
sures should be checked at least once a .,..
