U.S. DOT Tire Identification Number (TIN ) and tire
manufacture date
T his is the tire's "seria l number". It begins with the letters "DOT"
and indicates that the tire meets all federal standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac ­
ture. For example, the numbers 2209 mean that the tire was
produced in the 22nd week of 2009. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer. This information is used to contact consumers if a tire defect
requires a recall.
Audi Original tire
Tires with the identification "AO" or "RO" have been specially
matched with your Audi. We recommend using only these tires
because they meet the highest standards regarding safety and
driving characteristics when used correctly. Your authorized Audi
dealer will gladly prov ide you with more information.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support . Tire manufacturers also must indi­
cate the materia ls in the tire, which include steel, nylon, polyester,
and others.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire qual ity grading for treadwear , traction, and
temperature resistance
Tread wear, traction and temperature grades=> page 303.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system*
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans ­
mits this information to the tire pressure monitoring system*. If you
are going to replace the wheel rims on your vehic le, make sure the
new rims also have these sensors. The sensors must be compatible
with the tire pressure monitoring system* on your vehic le.
If you instal l rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring
system* wil l not work properly. In this case, the tire pressure moni ­
toring system* would not be able to monitor the tire pressure or
warn you if it is necessary .
• The battery inside of the tire pressure sensor has a limited
service life .
• Always drive with the valve stem caps secure ly mounted. We
recommend using factory instal led valve stem caps. Ask your autho ­
rized Audi dea ler to replace lost valve stem caps.
The installation of replacement tires with steel cord body p lies in
the tire sidewall may cause malfunction of the tire pressure moni­
toring system*, and is not recommended (cord material information
in molded on the tire sidewall).
Always check your tire pressure monitoring system* indicator after
replacing one or more tires on your vehic le. If the tire pressure
monitoring system* indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring system*, or some component of the
t ire pressure monitoring system* may be damaged. .._
