Uniform Tire Qu ality Gr ading
is a tire information system devel
oped by the United States Nation
al Highway Traffic Safety Admin
istration (NHTSA) that is designed
to help buyers make relative com parisons among tires. The UTQG
is not a safety rating and not a
guarantee that a tire will last for
a prescr ibed number of miles
(kilometers) or perform in acer
tain way. It simply gives tire buy
ers additional information to
combine with other considera
tions, such as price, brand loya lty
and dealer recommendations. Un
der UTQG, t ires are graded by the
tire manufacturers in three areas:
treadwear, traction, and tempera
ture resistance . The UTQG infor
mation on the tires, molded into
the sidewalls.
U.S. DOT Tire Identification
Number (TIN)
This is the tire's "serial 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 manufac
tured, and the last four numbers represent the
week and year of
manufacture . For example,
210
DOT ... 2215 ...
means that the tire was produced
in the 22nd week of 2015. The
other numbers are marketing co
des that may or may not be used by the tire manufacturer . This in
formation is used to contact con sumers if a tire defect requires a
recall.
Veh icle capacity weight
means the rated cargo and lug
gage load plus 150 lbs . (68 k ilo
grams) times the vehicle's desig
nated seating capacity .
Vehicle maximum load on the
tire
means that load on an ind ividual
tire that is determined by distrib
uting to each axle its sha re of the
maximum loaded veh ic le weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual
tire that is determined by distrib
uting to each axle its sha re of the
curb weight, accessory weight,
and normal occupan t weight (dis

,&. WARNING -
-Only use tire/rim combina
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident could result.
-For technical reasons, it is not possible to use tires from oth
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif
ferent construction can differ
greatly
even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged and this can reduce driving
safety and increase the risk of an accident.

-Only use tires that are more
than six years old when abso lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on your vehicle. Using them when not permitted can Lead to ve
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al

A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of
vehicle control and increase the risk of an accident. Read
and follow the important safe
ty precautions in¢
page 216,
Tires and vehicle load limits.
-The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the risk of an accident because it
can cause the tire to burst and result in loss of vehicle con
trol.
-Incorrect tire pressure in creases tire wear and has a
