2018 AUDI A7 wheel size

Wheels
- Traction AA A B C
- T emperature ABC
Quality grades can be found where appl icable on
the tire side wall between tread shoulder and
maximum section width
~ page 206, fig. 187.
For example: Tread wear 200, Traction AA, Tem ­
perature
A .
All passenger car tires must conform to Federal
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 contro lled conditions on a specified gov ­
ernment test course.
F or examp le, a tire graded
150 would wear one
and one half (1 1/2) times as well on the govern­
ment course as a tire graded
100.
The relative performance of tires depends upon
the actua l conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
d ifferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. T hose grades represent the tire's
abi lity to stop on wet pavement as measured un ­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
~ .&..
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to d iss ipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and reduce tire life,
and excess ive temperature can lead to sudden
tire
fa ilure ~.&. .
The grade C corresponds to a level of perform ­
ance which a ll passenger car tires must meet un-
222
der the Federal Motor Vehicle Safety Standard
No.
109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING -
The tract ion grade assigned to this t ire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics .
A WARNING
The temperature grade for this tire is estab­
lished for a tire tha t is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
-
-
Temperature grades apply to tires that are
proper ly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
ill General notes
Each tire, including the spare (if prov ided),
shou ld be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your veh icle has
t ir es of a diffe rent size t han the size ind icated on
the vehicl e placard or tire infl ation press ure la ­
bel, you sho uld determine the proper tire infla­
tion pressure for those tires).
As an added safety featu re, you r vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell ­
ta le when one or more of your tires is significant­
l y under-inflated. According ly, w hen the low tire
pressure telltale illuminates, you should stop and
check your t ires as soon as possible, and inflate
them to the proper pressure. Dr iving on a

pressure: System malfunction!.
If[m]J appears
after switching the ignition on or while driving
and the
RI] indicator light in the instrument clus­
ter blinks for approximately one minute and then
stays on, there is system malfunction. Try to
store the correct tire
pressures¢ page 224 . If
the indicator light does turn off or turns on again
after a short period of time, drive to an author­
ized Audi dealer or authorized Audi Service Facili­
ty immediately to have the malfunction correct­
ed.
A WARNING
- If the tire pressure indicator appears in the
display, reduce your speed immediately and
avoid any hard steering or braking maneu­
vers. Stop as soon as possible and check the
tires and their pressure .
- The driver is responsible for maintaining the
correct tire pressure. You must check the
tire pressure regularly.
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the tire pressure monitoring system
indicator may be delayed.
(D Tips
- The tire pressure monitoring system can al­
so stop working when there is an ESC mal­
function.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system in your
Audi was calibrated with "Audi Original
Tires"
¢ page 212. Using these tires is rec­
ommended .

Storing tire pressures
Applies to: vehicles with Tire P ressure Monitoring System in­
dicator
If the tire pressure changes or a tire is replaced,
it must be confirmed in the Infotainment sys­
tem.
.,. Make sure before storing that the tire pressures
of all four tires meet the specified values and
are adapted to the load

store now.
(D Tips
Do not store the tire pressures if snow chains
are installed.
Tire pressure monitoring
system
ill General notes
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
