run flat AUDI A8 2011 Owners Manual

252 Tir es and whe els
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 veh icle -
for example with winter tires - only use
the spare tire for a short period of time
and dr ive with extra care . Refit the nor­
ma l road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your veh icle
are rated because ti res that a re driven
faster than their rated speed can fail
sudden ly .
- Overloading t ires cause heat build- up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- T emperature grades app ly to tires that
are properly inflated and not over o r un ­
derinflated .
- For technical reasons it is not a lways
possible to use wheels from other vehi­
cles -in some cases not even whee ls
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle whee ls, make sure that the air f low
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 t ires may only be used on vehi­
cles that were equipped with them at the
factory . The vehicle must have a chassis
designed for run flat tires . Incorrect use
of run flat tires can lead to vehicle dam­
age or acc idents. Check with an a uthor­
ized Audi dea le r or tire specialist to see if
yo ur vehicle can be equipped with run
flat tires. If run f lat tires are used, they
must be insta lled on all four wheels. Mix­
ing t ire types is not permitted .
- Fo r technical reasons , it is not genera lly
possib le to use the whee l rims from oth­
er vehicles. This can ho ld true for wheels
of the same veh icle type. - If the spare tire is different from the
tires that yo u 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 w ith
extra care. Replace the flat tire w ith the
tire matching the others on your vehicle
as soon as possib le .
- Never drive without the valve stern cap .
The valves cou ld get damaged .
@) For the sake of the environment
Dispose of o ld tires in accordance with the
local requirements .
Uniform tire quality grading
-Tread wear
- Traction AA AB C
- Tempe ra tu re ABC
Quality grades can be found whe re applicab le
on the tire sid e wall betw een tr ead shou ld er
a nd maximum section width
c> page 249,
fig. 188 .
For ex ample: Tread wear 200 , Tract ion AA ,
Temperatur e A.
All passenger car t ires must conform to Feder­
al Safety Requirements in add ition to these
grades.
Tread wear
T he tread wear grade is a comparative rating
based on the wear rate of the t ire when tes ted
u nder contro lled cond itions on a specified
government test course .
For example, a tire graded 150 would wear
one and one ha lf (11/2) times as well on the
government course as a tire graded 100.
T he relative performance of tires depends
upon the actual conditions of thei r use, how­
ever, and may depa rt s ignificantly from the
norm due to va riations in driving hab its, se rv­
ice practices and differences in road character -
istics and cl imat e. ..,.

258 Tires and wheels
pressure label~ page 242 . Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, winter condit ions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your vehicle or accidents
cou ld also result.
(D Tips
- The tire pressure monitoring system
stops working when there is an ESP/ABS
malfunction.
- Using snow chains may result in a system
malfunction.
- To ensure a proper TPMS function use
AUDI Original Tires which are marked
with "AO" or "RO" on the tire sidewall.
~p age 249.
- The tire pressure monitoring system on
your Audi was syntonized using tires with
the "AO" or "RO" identification. We rec­
ommend using these tires.
Reset tire pressure monitoring system
App lies to vehicles: with tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI .
.. Switch on the ignition .
.. Se lect in the MMI: !CAR !function button>
Car systems contro l button > Servicing &
checks > Tire pressure monitoring > Store
tire pressures > Yes, store now.
(D Tips
Before resetting the TPMS, the current
pressures of all four tires must correspond
to the specif ied values. Adjust the tire
pressure and reset the pressure in the tire
pressure monitoring system according to
the load you are carrying~ page 242.
- Do not store the tire pressures if you are
dr iving with snow chains. Otherwise, a
system malfunction may occur.
