-All four wheels must be fitted with radial
tires of the same type, size (rolling cir
cumference) and the same tread pattern .
Driving with different tires reduces vehi
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time and drive with extra care. Refit the nor
mal road wheel as soon as safely possi
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un
derinflated .
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air
flow to the brakes can them to overheat,
increasing stopping distances and caus
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them at the factory. The vehicle must have a
chassis designed for run flat tires. Incor
rect use of run flat tires can lead to vehi
cle damage or accidents. Check with an
authorized Audi dealer or tire specialist
to see if your vehicle can be equipped
with run flat tires. If run flat tires are
used, they must be installed on all four
wheels . Mixing tire types is not permit
ted.

@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth
er vehicles. This can hold true 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
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
¢ page 284,
fig. 253.
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100. •

snow cha in manufacturer when doing so .
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains because the vehicle will be ex
tremely low. If you do dr ive with snow
chains on while the vehicle is at this lev

age the wheelhouse and other parts of
the veh icle.
(!) Tips
Where snow cha ins are mandatory oncer

veh icles with all-whee l dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If different rims are fit
ted, the correct wheel bolts with the r ight
l ength and correctly shaped bolt heads must
be used. This ensures t hat wheels a re fitted
secure ly and that the brake system f unctions
correctly .
I n ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
<=?page 318.
.&_ WARNING
Improperly tightened o r maintained wheel
bolts can become loose ca using loss of
contro l, a co llision and serious persona l 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 bo lts and
the threads in the wheel hubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specified
torque. -
On ly use wheel bolts that be long to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct tightening
torque for the whee l bolts to reduce the
risk of a whee l loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is mov ing. If the tightening torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be
come loose.
(D Note
The specified torque for the wheel bolts is 120 ft lb ( 160 Nm) with a to le rance of
± 7,4 ft lb( ± 10 Nm) . T orque wheel bolts

Low aspect ratio tires

T he low aspect ratio of these t ires is ind icated
