198 Tires and wheels
Groove
means the space between two adjacent tread
ribs .
Load rating (code)
means the maximum load that a tire is rated
to carry for a given inflation pressure. You
may not find this informat ion on all tires be
cause it is not req uired by law.
Maximum load rating
means the load rating for a t ire at the max i
mum permissible inflation pressure for that
tire.
Maximum loaded vehicle weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity we ight, and
(d) Production options weight
Maximum (permissible) inflation pressure
means the maximum cold inflation pressure
to which a tire may be inflated. Also called
"maximum inflation pressure ."
Normal occupant weight
means 150 lbs. (68 kilograms) times the
number of occupants seated in the vehicle up
to the total seating capacity of your vehicle .
Occupant distribution
means distribution of occupants in a vehicle.
Outer diameter
means the overa ll diameter of an inflated new
tire.
Overall width
means the linear distance between the exteri
ors of the sidewalls of an inflated tire, includ
ing elevations due to labeling, decorations, or
protective bands o r ribs .
Ply
means a layer of rubber-coated parallel cords.
Production options weight
means the combined weight of those insta lled
regular production options weighing over 5
lb s. (2 .3 kg) in excess of those standard items
which they replace, not previously considered
in curb weight or accessory we ight, including
heavy duty brakes, ride levelers, roof rack,
heavy duty battery, and special tr im .
Radial ply tire
means a pneumat ic tire in which the ply cords
that extend to the beads are laid at substan
t ia lly 90 degrees to the center line of the
tread .
Recommended inflation pressure
see <=> page 19 7, Cold tire inflation pressure.
Reinforced tire
means a t ire designed to operate at higher
loads and at higher inflation pressures than
the cor responding standard tire. Reinf orced
ti res may be identified as "XL" , "xl", "E XTRA
LOAD", or "RF" on the sidewall.
Rim
means a metal support for a tire or a tire and
tube assembly upon which the tire beads are
seated.
Rim diameter

you change your wheel s ize, you will have to
purchase new tires to match the new rim di
ameter.
Rim size designation

Rim width
means nominal distance between rim flanges.
Sidewall
means that portion of a tire between the
tread and bead.

The effectiveness of the tire pressu re monitor
ing system w ill be impaired if you store nor

Because technical changes may be made to
ve hicle equipment during the model year, a l
ways compare the tire size designation on the tire press
ure label on your vehicle with the
tires on your vehicle. Make sure that the tire

same as the size of the tires on the veh icle .
This is especially important if the vehicle be-

quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists.
When the malfunct ion indicator is ill uminat
ed, the system may not be able to detect or
signa l low tire pressure as intended. TPMS
malfunct ions may occur for a variety of rea
sons, including the installat ion of replace
ment or alternate tires or wheels on the veh i
cle that prevent the TPMS from funct io ni ng
properly. Always check the TPMS malfunct ion
tellta le afte r replacing one or more t ires or
wheels on your veh icle to ensure that the re
p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig. 1 47 Disp lay : under infla tion warn ing
Using the ABS sensors, the tire pressure moni
toring system compares the t ire tread circum
fe rence and vibration characteristics of the in
d iv idual tires . If the pressure decreases in one
or mo re tires, th is is indicated in the instru
ment clus ter with a warning symbol
RE and a
message
'* fig. 147. The dr iver message in the
d isp lay goes out after 5 seconds. The driver
message can be d isplayed again by pressing
the
! CHECK I button @¢ page 10, fig . 3 . If on
ly one tire is affected, the display will indicate
its pos ition.
The ti re pressure monito ring m ust be reset in
the menu display each time the pressures are
ad justed (e.g. when switching between parti-
Tire s an d wheel s 215
al and fu ll load pressure) or after changing o r
replacing a tire on your vehicle '*
page 216.
The TPMS indicator on ly mon itors the t ire
pressure that you have previously stored . You
can f ind the recommended tire pressures for
your vehicle on the label on the driver's door
pillar ¢
page 200.
Tire tread circumference and vibration charac
teristics can change and cause a tire pressure
warning if:
- the t ire press ure in one or more tires is too
low,
- the tire has structural damage,
- the t ire press ure was changed, wheels rotat -

- If the tire pressure ind ic a tor ap pears in

218 Tires and wheels
When it is not possible to continue
driving , even with run-flat tires?
-If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the
Tire Pr essure Monitoring System does
not work .
- If the tire has been severely damaged, in a
crash , for example. The tread can separate
from a damaged tire as the wheel turns, and
hit parts of the vehicle, such as the fuel tank
filler neck , fuel lines or brake lines.
- Do not continue driving if severe vibration occurs or if the tire starts to smoke because
the tire is running hot.
- Do not continue driving if damage to the
tire, such as cracks in the sidewall, appears.
A WARNING
Improper use of run-flat tires can cause
vehicle damage that can lead to loss of ve
hicle control, a crash and serious personal
lnJUry.
- Run-flat tires can only be used with spe
cial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire Pre
ssu re Monit oring Sys tem.
- Always inspect a tire that has lost air to
make sure it is safe to drive with the tir e
in the run-flat mode.
- Never drive with run-flat tires that have
been damaged in a collision.
- Never drive with run-flat tires if heat
build-up causes the tire to give off
smoke.
- Never drive with run-flat tires if the vehi
cle shakes or vibrates severely.
- Never drive with a run-flat tire that de
velops sidewall cracks or other damage
wh ile in use .
-If you switch between standard and run
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module.
(D Note
Run-flat tires have specia l characteristics
and requirements, that are very different
from conventional tires. Run-flat tires re
quire special rims for run-flat use and can
not be used on conventional wheel rims.
(D Tips
- If you are not able to cont inue driv ing
w ith run-flat tires, please seek professio
nal assistance.
- Please contact your authorized Audi
dealer or Audi of America, Inc. if you
have questions about tires and rims .
Driving with run-flat tires
Applies to vehicles: wit h Run -flat tires
Handling characteristics change when tire
pressure is low .
Driving on tires with low tire pressure changes
the way a veh icle handles, particularly when
cornering and braking. The handling charac
teristics of run-flat tires do not seem to
change a lot even when driving on low pres
sure or in the run-flat mode . Nevertheless you
must still take spec ia l precautions when oper
at ing a vehicle on run-flat tires when tire pres
sure is low o r the tire(s) is flat:
.,. Th e Electronic Stabilization Control (ESC)
must be switched on.
.,. Never drive faster than SO mph (80 km/h)
q &_ .
.,. Plan ahead when driving and anticipate
what you will have to do considering traffic
and road conditions up ahead .
.,. Accelerate carefully.
.,. Avo id unnecessary and sudden steering and
brak ing maneuvers .
.,. Reduce your speed in plenty of time before
intersections, curves and other places where
you may have to react qu ickly.

ble to continue driving, even with run-flat
