Tread separation
means pulling away of the

Uniform Tire Quality Grading
is a tire information sys tem de­
veloped by the United States
National Highway Traffic Safety
Administration (NHTSA) that is
designed to help buyers make
relative comparisons among
tires. The UTQG is not a safety
rat ing and not a guarantee that
a tire will last for a prescribed
number of miles (kilometers) or
perform in a certain way. It
simply gives tire buyers addi­
tional information to comb ine
with other considerations, such as price, brand loyalty and deal­
er recommendations. Under
UTQG, tires are graded by the
tire manufacturers in three areas: treadwear, traction, and
temperature resistance . The UTQG information on the t

U.S. DOT Tire Identification
Numbe r (TIN )
,
This is the tire's "serial num­
ber" . It begins with the letters
"DOT" and indicates that the
tire meets all federal stand­
ards . The next two numbers or
letters indicate the plant where
it was manufactured, and the
last four numbers represent the
week and year of manufacture. F or example,
DO T ... 2214 ...
means that the tire was pro­
duced in the 22nd week of
2014. The other numbers are
marketing codes that may or
may not be used by the tire
manufacturer. This information
is used to contact consumers if
a tire defect requires a recall.
Vehicle capacity weight
means the rated cargo and lug­
gage load plus 150 lbs. (68 kilograms) times the vehi­

If you wish to improve comfort
when operating the vehicle at
normal load (up to 2 occu­

pressures to those specified
for normal vehicle load. Before
operating the vehicle at maxi­ mum load, you must increase

236 Tires and wheels
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa­
tion on the tire pressure label
on your vehicle with the tires on
your vehicle . Make sure that the
tire size information on the ve­ hicle label is the same as the
size of the tires on the vehicle .
This is especially important if
the vehicle belongs to someone else or you bought the vehicle
with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and
that of your passengers also de­ pends on making sure that load
limits are not exceeded . Vehicle
load includes everybody and ev­
erything in and on the vehicle .
These load limits are technical­ ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"). The Gross Axle
Weight Rating ("GAWR") is the
maximum load that can be ap­
plied at each of the vehicle's
two axles . The Gross Vehicle
Weight Rating and the Gross
Axle Weight Rating are listed on the safety compliance stick- er label located on the driver's
side B-pillar. The tire pressure
label on your Audi lists the
maximum combined weight of
all of the occupants and lug­
gage or other cargo that the ve­
hicle can carry. For the location
of the tire pressure label

&_ WARNING
-
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death .
- Carrying more weight than
your vehicle was designed to carry will prevent the ve­
hicle from handling properly
and increase the risk of a
loss of vehicle control.
-The brakes on a vehicle that has been overloaded may
not be able to stop the vehi­
cle within a safe distance.
- Tires on a vehicle that has
been overloaded can fail
suddenly causing loss of
control and a crash.
-Always make sure that the total load being transported
does not make the vehicle .,.

heavier than the vehicle's
Gross Vehicle Weight Rat­
ing.
& WARNING
-Incorrect tire pressures and/or underinflation can lead to a serious or fatal ac­
cident.
-Incorrect tire pressures and/or underinflation cause increased tire wear and can
affect the handling of the
vehicle.
-Incorrect tire pressures and/or underinflation can
also lead to sudden tire fail­
ure, including a blowout
and sudden deflation, caus­ ing loss of vehicle control.
Checking tire pressure
The correct tire pressure for the
tires originally installed on
your vehicle is listed on the tire
pressure label located on driv­er's side 8-pillar.
The recommended tire pres­sures are on the tire pressure
label and in the table
¢ page 233, Cold tire inflation
pressure .
This means that the
pressure must be checked and
Tires and wheels 237
adjusted when the tire has not been driven for more than a
couple of miles (kilometers) at low speeds during the previous
three hours. Air in the tires ex­ pands when the tire heats up as
a result of internal friction as 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. There­
fore, you should never let air out of a warm tire to match
"Cold tire inflation pressure"
recommendations ¢
page 233.
The tires would then be under­
inflated and could fail sudden­
ly.
The tire pressure label on your
Audi lists the recommended cold tire inflation pressures at maximum capacity for the new,
original equipment tires that
were on your vehicle at the time
it was manufactured . For the
location of the label

the driver observe the speci­
fied tire pressure values for
the tires and the correct pressures for the function of
the tire pressure monitoring
system.
-Always inflate tires to the
recommended and correct
tire pressure before driving
off.
-Driving with underinflated tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­
loading can cause heat
build-up, sudden tire failure
and loss of control.
-If the tire pressure is too low or too high, the tires
will wear prematurely and
the vehicle will not handle
well.
-If the tire is not flat and you do not have to change a
wheel immediately, drive at reduced speed to the near­
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem
caps on all wheels are secure­ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi­
cle and any tire can carry. Ave­ hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can
not only lead to loss of vehicle
control, but can also damage
important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your passengers also depends on
making sure that load limits are~
