Maximum loaded vehicle weight
means the sum of:
(a) Curb weight
(b) Accessory weight
(c) Vehicle capacity weight, and
(d) Production options weight
Maximum (permissible) inflation pressure
means the maximum cold inflation pressu re
to which a tire may be inflated. Also called
"maximum inflation p ressure."
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 inf lated new
tire.
Overall width
means the linear distance between the exteri­
ors of the sidewalls of an inflated tire, includ­
ing e levations due to labeling, decorations, or
protective bands or ribs.
Ply
means a layer of rubber-coated parallel cords.
Production options weight
means the comb ined weight of those installed
regular production options weighing over 5
lbs . (2 .3 kg) in excess of those standard items
which they replace, not previously considered
in curb weight or accessory weight, including
heavy duty brakes, r ide leve lers, roof rack,
heavy duty battery, and specia l trim .
Radial ply tire
means a pneumatic tir e in which the p ly cords
that extend to the beads are laid at substan­
tially 90 degrees to the centerline of the
tread . Recommended inflation pressure
see
~
page 213, Cold tire inflation pressure.
Reinforced tire
means a t ire designed to operate at higher
loads and at higher inflation pressures than
the corresponding standard tire . Re inforced
t ir es my be identified as "XL", "xl", "EX TRA
LOAD", or "RF" on the sidewall.
Rim

be driven for extended periods of time. The
ratings range from 93 mph (150 km/h) to
186 mph (298 km/h)
~ page 224 . You may
not find this information on all tires because
it is not requ ired by law.
The speed rating letter code, where applica­
ble, is molded on the tire sidewall and indi­
cates the max imum pe rmissibl e road speeds

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.

unbalanced, resulting in vib rations you can
usually feel through the steering wheel.
Unba lanced wheels mus t be rebalanced to
avoid excessive wea r on s teer ing, suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Inco rrect whee l alignment can cause exces­
sive tire wea r, impair ing t he safety of the veh i­
cle. If t ires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Ve hicles w it h quattro ® must always have t ires
of the same s ize, construction and tread type.

A WARNING
Sudden tire failure can lead to loss of con­
tro l, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard , they do
not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency and then with special care and at lower
speeds .
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss o f vehicle con trol.

T he tires and rims are essential parts of the
vehicle's des ign . The tires and rims approved
by Audi are specia lly matched to the charac ­
teristics of the ve hicle and can make a major
contribution to good road holding and safe ..,.

226 Tires and wheels
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 vehi­
cles -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 vehi­ cles that were equipped with them at the
factory. The vehicle must have a chassis designed for run flat tires and a factory­
installed tire pressure monitoring sys­
tem* that indicates a loss of tire pres­
sure . Incorrect use of run flat tires can
lead to vehicle 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
permitted .
(D 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 ti re 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.
- If you put different wheels and tires on
your vehicle (e .g. winter wheels and
tires), you must be certain that the
wheels and tires are compatible with the
tire pressure monitoring system* . Other ­
wise the system will register a malfunc­
tion and a fault message will be dis­
played. For more information, contact
your authorized Audi dealer.
- 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 223,
fig. 171 .
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 150 would wear
one and one half (11/2) 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
ll-

@ Tips
-Where snow chains are mandatory on
certain roads, this normally also applies
to vehicles with All Wheel Drive .
- If snow chains are insta lled, the tire
pressures shou ld not be stored in the tire
pressure monitoring system (TPMS).
Otherwise the system could malfunction
¢page 232.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts wit h the right
length and correctly s haped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the bra ke system f unctions
cor rectly .
In certain circumstances, you may not use
wh eel bolts from a differ ent vehicle -even if it
i s the same mode l.
.&, WARNING
Improperly tig hte ned o r maint ained wheel
bol ts can become loose ca using loss of
cont ro l, a co llision and ser ious persona l in ­
jury.
- Always keep the wheel bolts an d the
threads in the wheel hubs clean so the
whee l bolts can tu rn easily and be pro p­
er ly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the w heel hubs. They can
become loose w hile driving if greased or
o iled, even if tightened to the specified
torq ue.
- Only use wheel bolts t hat belong to the
r im being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tighten ing
torq ue for the wheel bo lts t o reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 229
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as so on as possible with a
torq ue w rench -prefe rably by an au thor ­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng u nder a var iety of driving condi­
tions . Ask your au thorized Aud i dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numera l represen ts the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in perce ntage. Conven­
tiona l tires have a he ight/w idth ratio of 60 o r
more.
The performance of low-a spect-ratio tires i s
particularly sensitive to improper inflation
pre ssure.
It is therefore important that low
aspect ratio tires are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 218, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.
