¢
page 206, Tread Wear Indicator (TWI) for
more informat ion on measuring tire wear.
Uniform Tire Quality Grading
is a tire information system developed by the
United States National Highway Traffic Safety
Admin istration (NHTSA) that is designed to
help buyers make relative comparisons among
tires . Th e U TQG is not a safety rating and not a
g ua ran tee that a tir e will las t for a prescribed
number of mi les or per form in a certain way.
It simply gives tire buyers additional informa­
tion to combine with other considerations,
Tires and wheels 199
such as price, brand loyalty and dealer recom­
mendations . Under UTQG, tires are graded by
the tire manufact urers in three areas: tread­
wear, traction and temperature resistance .
The UTQG informat ion on the tires, molded in­
to 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 federa l 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 manufacture.
For example,
DOT ... 2211 ...
means that the tire was produced in the 22nd
week of 2011. The other numbers are market­
ing 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 luggage load plus
150 lbs . (68 k ilograms) times the vehicle's to­
tal seating capacity as listed on the label lo­

means that load on an individual tire that is
determined by distributing to each axle its
share of the maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual tire that is
determined by distributing to each ax le its
share of the curb weight, accessory weight,
and normal occupant weight (distr ibuted in
accordance with table below¢
page 200)
and dividing by two.

Cold tire inflation pressure
Tire pressure affects the overall handling , p erformance and safe ty of a vehicle.
Fi g. 14 2 T ire p ress ure la b el: loca ted on driver's side B·
p ill ar
Tire pressure genera lly refers to the amount
of air in a t ire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nterna·
tional measur ing unit and in pou nds pe r
squa re inc h (PSI). Tire pressure is based in
par t on the vehicle's desig n and load limit -
the greatest amoun t of weight that the vehi·
cle can carry safe ly and the t ire size . The prop·
er tire pressure is freq uently referred to as the
" recommended cold tire inf lation pressure."
A ir in the tires expands when the tire heats up
because of internal frict ion when it flexes in
use . The t ire p ressu re is higher when the tire
h as wa rmed up tha n when it is "cold ." It is the
in flat io n pressu re i n a "cold" tire that counts.
Th erefore, you shou ld neve r let air ou t of a
warm tire to match " co ld tire inflat ion pres­
sure" recommendations . The t ires wo uld then
be underinflated and could fail su ddenly .
M ain taining p roper t ire pr essu re is one of the
most im po rt an t th ings you ca n d o to he lp
avoid sudden tire failure. Underin fla ted t ires

i n g tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

the vehicle as a previously owned vehicle.
Remembe r, your safety and that of your pas­
sengers also depends on mak ing sure that
l oad limits are not exceeded . Vehicle load in­
cludes everybody and everything in and on the
ve hicle . These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the veh icle 's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rat ing a re listed on the
safety compliance st icker labe l located on the
d river's side B-pi llar. T he tire pressure label on
your Audi lists the maximum combined weight of a ll of the occupants and luggage or
othe r cargo that the vehicle can carry. For the
locat ion of the tire pressure label¢
fig. 142.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
r ious personal injury, and even death.
- Carry ing more weight than your vehicle
was designed to carry will prevent the
vehicle from handling p roperly and in­
c rease the risk of a loss of veh icle con­
tro l.
- T he brakes on a veh icle that has been
overloaded may not be ab le to stop the
vehicle within a sa fe distance.
- Ti res on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
tro l and a crash .
A WARNING
-Incorre ct tire pressures and/or underin­
flation can lead to a serious o r fatal acci ­
dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can affect the handling of the vehicle .
- Incorrect tire pressures and/o r underin­
flation can also lead to sudden tire fai l­
ure, incl uding a blowo ut and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­ lar.
The recommended tire pressures are on the
t ire pressure label and in the table
¢
page 200, Cold tire inflation pressure. This
means tha t the pressu re must be che cked and
adjus ted whe n the t ire has not been dr iven fo r
more than a couple of miles (kilometers) at
l ow speeds d uring the previous t hree ho urs.
Air in the tires expands when the tire heats up
as a result of interna l 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 "co ld" tire that
counts. Therefore, you should never let air out
of a warm tire to match "Cold tire inflat ion
pressure" recommendat ions ¢
page 200 . The
t ires would then be unde rinflated and could
fail suddenly .
The tire pressure label on your Audi lists the
recommended co ld tire inflation pressures fo r
the new, orig inal equ ipment tires that were
on your veh icle at the time it was manufac­
tu red. Fo r the location of the labe l
¢page 200, fig . 142.
Most t ires lose air naturally over t ime . They
can a lso lose some air if you d rive over a pot­
hole or hit a curb while park ing. It is usually
not poss ible to see whethe r the rad ial tires
u sed today are underinfla ted just by loo king
at them .
T he refore, be sure to check t ire p ressu res at
least on ce a mo nth and a lways befo re going
on a long trip. Ma ke s ure to ta ke the n umbe r
of peop le and the amount of luggage into ac ­
count when adjusting tire pressure for a trip -
even one that yo u wo uld not consider to be
"long." See ¢
page 204, Tires and vehicle
load limits
for more important information.
Always use an accurate tire press ure ga uge
when checking and ad justing inflation pres­
s u res. Check all of the tires and be sure not to ..,.

204 Tire s and wheel s
-If the tire pressure is too low or too high,
the tires w ill wear prematurely and the
vehicle will not handle well.
- If the tire is not flat and you do not have
to change a wheel immed iately, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Dr iving without valve stem caps can cause
damage to the t ire va lves. To prevent this,
always make sure that facto ry installed
valve stem caps on all wheels a re securely
mounted on the valve.
@ For the sake of the environment
Underinf lated tires will a lso increase the
fue l cons umption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can c arry.
A vehicle that is overloaded w ill not h andle
well and is more difficult to stop. Over load ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the veh icle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and eve ryth ing in and on the vehicle . These
l oad limits a re tech nica lly refe rred to as the
ve hicl e's
Gros s Vehicl e W eight Rat ing
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory installed accesso ries , a fu ll
tank of f uel , oi l, coo lant and othe r fluids plus
maximum load. The maxim um load includes
the number o f passengers that the vehi cle is
intended to carry ("seating capacity") with an
assumed weig ht of 150 lbs (68 kg) for each
passenger at a designated seating position and the total weight of any luggage
in the ve ­
hicle .
T he
Gro ss Axle Weight Rating (" GAWR") is
the max imum load th at can be applied at e ach
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weight Ra ting are listed on the
sa fety comp liance s ticke r label lo cated on the
driver's side B-pillar. Your Audi has 4 seat ing
positions, 2 in the front and 2 in the rear fo r
total seat ing capac ity of 4. Each seating posi­
t ion has a safety be lt c>
page 100 , Safety
bel ts.
The fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage.
The tire pressure label on your Aud i also lists
the max imum combi ned weig ht of all of the
occupants and luggage or other cargo t hat
t h e vehi cle can carry . Fo r th e lo cat ion of the
la bel c>page200,
fig.1 42.
_& WARNING ~
Overloading a vehicle can c ause loss o f ve-
h icle cont ro l, a c rash or other accident, se ­
rious pe rsonal injury, and even death.
- Ca rrying more we igh t tha n your veh icle
was des igned to carry wi ll prevent the
veh icle from handling proper ly and in­
crease the risk of the loss of ve hicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance .
- Tires on a vehicle that has been over load­
ed can fail s uddenly , incl uding a blowout
a nd sudden deflation, causing loss of
control and a crash .

Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi­
cle's placard (tire inflation pressure label)
¢ page 200,
fig . 142 .
2. Determine the combined
weight of the driver and pas­ sengers that will be riding in
your vehicle .
3 . Subtract the combined
weight of the driver and pas­ sengers from
"XXX" kilo ­
grams or
"XXX" pounds
shown on the sticker
¢ page 200 , fig. 142.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
Tires and wheels
and there will be five 150 lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­ pacity is 650 lbs. (1400-7 50
(5
X 150) = 650 lbs.)
5 . Determine the combined
weight of luggage and cargo
being loaded on the vehicle .
That weight may not safely exceed the available cargo
and luggage load capacity
calculated in Step
4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­duces the available cargo
and luggage load capacity of
your vehicle.
