254 Tires and wheels
-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.
- 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
~fig. 195.
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.
Fo r example, a tire graded 150 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use, how
ever, and may depart significantly from the
norm due to variations in driving habits, serv
ice practices and differences in road character
istics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as ..,.

@ Tips
Check carefully to make sure the hook-up
is secure before moving the car up the flat
bed truck ramp.
Vehicle transport
Whenever you have your vehicle transported,
be sure to note the following:
(D Note
Mount the tie-down chains/cables over the
running surface (circumference) of the
tires. Never secure the vehicle by the axle,
the suspension struts or the front or rear
towline eye. For technical reasons, the
pressure in the suspension struts may
change during the transport and this will
adversely affect vehicle handling.
Lifting vehicle
Lifting with workshop hoist and with
floor jack
The vehicle may only be lifted at the lifting
points illustrated.

"' Insert a rubber pad between the floor jack/
workshop hoist and the lifting points .
The vehicle jack mode* must be activated so
that the automat ic adjustment of the Adap

difficult to raise the vehicle with the floor
jack .
If you must lift your vehicle with a floor jack
to work underneath, be sure the vehicle is
safely supported on stands intended for this
purpose.
Front lifting point
The lifting point is located on the floor pan re
inforcement about at the same level as the
jack mounting point
¢fig. 221. Do not lift
the vehicle at the vertical sill reinforcement .
Rear lifting point
The lifting point is located on the vert ical rein
forcement of the lower sill for the on-board
jack ¢

A WARNING
-To reduce the risk of ser ious injury and
veh icle damage.
- Always lift the vehicle only at the spe
cial workshop hoist and floor jack lift
points illustrated
¢fig. 221 and
¢ fig. 222.
-Failure to lift the veh icle at these
points could cause the vehicle to tilt or
fall from a lift if there is a change in ve
hicle weight distribution and balance.
