Production options weight
means the comb ined weight of those installed
regular production options weighing over 5

Recommended inflation pressure
see ~ page 190, Cold tire inflation pressure.
Reinforced tire
means a t ire designed to operate at higher
loads and at higher inflat ion pressures than
the corresponding standard tire. Re inforced
ti res my be ident ified 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
means nom inal d iameter of the bead seat. If
you change your wheel s ize, you w ill have to
purchase new tires to match the new r im di­
ameter.
Rim size designation
means r im diameter and width.
Rim width
means nom inal distance between rim fla nges.
Sidewall
means that portion of a tire between the
tread and bead.
Speed rating (letter code)
means the speed at which a tire is designed to
be driven for extended periods of time. The
ratings range from 93 mph (150 km/h) to
186 mph (298 km/h)
~ page 200 . You may
not find this information on all tires because
it is not requ ired by law.
T he speed rating letter code, where applica­
ble, is molded on the tire sidewall and indi­
cates the maximum pe rm issib le road speeds
~ .&. in Winter tires on page 204.
Tire pressure monitoring system
means a system that detects when one or
more of a veh icle's tires are underinflated and
illuminates a low tire pressure warning tell­
tale.

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 150 Tire pressure label: located on driver's side B·
pillar
Tire pressure generally refers to the amount
of air in a tire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals (kPa), the interna­
tional measuring unit and in pounds per
square inch (PSI). Tire pressure is based in
part on the vehicle's design and load limit­
the greatest amount of weight that the vehi­
cle can carry safely and the tire size. The prop­
er tire pressure is frequently referred to as the
"recommended cold tire inflation pressure."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "cold." It is the
inflation pressure in a "cold" tire that counts.
Therefore, you should never let air out of a
warm tire to match "cold tire inflation pres­
sure" recommendations. The tires would then be underinflated and could fail suddenly.
Maintaining proper tire pressure is one of the
most important things you can do to help
avoid sudden tire failure. Underinflated tires
are a major cause of sudden tire failure. Keep­
ing tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,
traction, braking and load carrying .
Tire pres­
sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci­
ties approved for your vehicle.

INFOl n
u
The recommended tire pressures for your Audi
depend on the kind of tires on your vehicle
and the number of passe ngers and/or amount
of luggage you will be transporting.
The tire pressure label located on driver's side
B-pillar on your Audi lists the recommended
cold tire inflation pressures for the vehicle at
its maximum capacity weight and tires that
were on your vehicle at the time it was manu­
factured.
If you wish to improve comfort when operat­
ing the vehicle at normal load (up to 2 occu­
pants), you can adjust tire pressures to those
specified for normal vehicle load. Before oper­
ating the vehicle at maximum load, you must
increase the tire pressures to those specified
for maximum vehicle load
9 .&.
Bear in mind that the tire pressure monitoring
system can only monitor the tire pressures
that are stored. The system does not recog­
nize the load condition of your vehicle.
See the illustration,:;,
fig. 150 for the location
of the label on driver's side B-pillar (color of
the actual label and exact location on the ve­
hicle will vary slightly).
Note that the following table is accurate at
the time of going to press and is subject to
change. In the event of discrepancies, the tire
pressure label on driver's side B-pillar always
ta kes precedence. ..,.

208 Tir es and whee ls
- The tire pressure monitoring system
helps the driver to keep an eye on tire
pressures. But the driver st ill has the re­
sponsibility for maintaining the correct
tire pressure.
- Tire pressure must only be adjusted
when the temperature of the tires is
about the same as ambient air tempera­
ture.
- When tires are replaced, the sensors and
valves should not be exchanged . The
valve core, nut, valve sealing and seal
washer (rep lacement kit) needs to be re­
placed. If necessary, the valve and the
whee l electronics have to be rep laced.
- The tire pressure monitoring system on
your Audi was calibrated us ing tires w ith
"RO" identification. We recommend us­
i ng these tires.
- If you should put different whee ls and
ti res on yo ur vehicle (e.g. w inter wheels
and tires), yo u m ust be certain that the
whee ls and tires are compatible with the
tire pressure monitoring system . Other­
wise the system w ill reg ister a ma lfunc­
tion and a fault message will be d is­
played . For more information, contact
your authorized Audi dealer .
