especially at high speeds . Tires that are more than 6 year s old can
only be used in an emergency and then with special care and at low
s peed .
Glossary of tire and loading terminology
Accessory weight
means the combined we ight (in excess of those sta nda rd items which
may be rep lace d) of automatic transmission, power steering, power
bra kes, powe r w indows , power seats, radio, and heater, to the extent
that these items are avai lab le as factory- installed equipment
(w het he r i nsta lled or no t).
Aspect ratio
me ans the ratio of t he he ight to t he w id th of the tir e in percent .
Numbe rs of 55 o r lower indicate a low sidewa ll for improved steer ing

Sidewall

Speed rating (letter code)
means the speed at which a tire is designed to be driven for extended

mph (298 km/h) =>
page 307. You may not find this information on
all tires because it is not required by law.
The speed rating letter code, where applicable, is mo lded on the tire
sidewall and indicates the maximum permissible road speeds=>
& in
"Winter tires" on
page 309.
Tire pressure monitoring system*

Tread separation
means pulling away of the tread from the tire carcass.
Treadwear indicators (TWI)
means the projections within the princ ipal grooves designed to give a
visual ind ication of the degrees of wear of the tread. See=>
page 304,
"Tread Wear Indicator (TWI)" for more information on measuring
tire wear.
Uniform Tire Quality Grading
is a tire informat ion system developed by the United States National
H ighway Traff ic Safety Adm inistration (NHTSA) that is designed to
help buye rs make relative comparisons among tires. The UTQG is not
a safety rating and not a guarantee that a tire will last for a prescribed
number of miles or perform in a certain way. It simply gives tire
buyers additional information to comb ine with other considerations,
such as price, brand loyalty and dealer recommendations. Under
UTQG, tires are graded by the tire manufacturers in three areas: treadwear
, traction and temperature resistance. The UTQG informa­
tion on the tires, molded into the sidewa lls.
U.S. DOT Tire Identification Number (TIN)
This is the tire's "ser ial number" It begins with the letters "DOT" and
indicates that the tire meets all federal standards. The next two
numbers or letters ind icate the plant where it was manufactu red, and
the last four numbers represent the week and year of manufacture.
For examp le,
DOT ... 2209 ...
means that the tire was produced in the 22nd week of 2009. The
o ther numbers are marketing codes that may or may not be used by
the t ire manufacturer. Th is informat ion is used to contact consumers
if a tire defect requires a recall.
Vehicle capacity weight
means the rated cargo and l uggage load plus 150 lbs. (68 kilograms)
times the vehicle 's total seating capacity as listed on the label located
on the driver's side B-pillar.
Vehicle maximum load on the tire
means that load on an individual tire that is determined by dist rib­
uting to each axle its share of the maximum loaded vehicle weight
and divid ing by two.
Vehicle normal load on the tire
means that load on an individua l tire that is determined by distrib­
uting to each axle its share of the curb weight, accessory weight, and
normal occupant weight (distributed in accordance with table below
=>
page 297) and dividing by two. .,_

Tire pressure generally refers to t he amo unt of a ir i n a tire tha t it
needs it to do its job and safe ly carry the comb ined load of t he entire
vehicle and its contents . Tire p ressure is measured in kilopasca ls
(kPa), the inte rnationa l measur ing unit and in poun ds per squar e in ch
(PSI). Tire press ure is based in part on the ve hicle 's design and load
limit -the greatest a mount of weight that the vehi cle can c arry safe ly
and the tire s ize. The proper tire pressure is frequently refer red to as
the "re commen ded cold t ire inflation p ressure. " Air in t he tires
expands when the tire heats up because of internal friction when it
flexes in use. T he tire press ure is hig her w hen the tir e h as warme d up
than whe n it is "cold." It is the inflation pressure in a "cold" tire that
c o unts. The refo re, you sho uld never let air o ut of a warm t ire to
match "cold ti re inflation pressure " recommendations . The t ires
wou ld then be under in flated and could fail s uddenly.

Ma intain ing prope r tire pressure is one o f the most importa nt things
you can do to he lp avoid sudde n tir e fa il u re . Under inflated tires are a
majo r ca use of sudden tire fa ilure . Keeping t ires at the rig ht pressure
is a lso important for safe and responsive vehicl e ha nd ling , traction,
braki ng an d load ca rryi ng.
Tire pressures are particularly impo rtant
when the vehicle is being driven at higher speed s, and then espe·
cially when heav ily loaded even within the permissible load ·
carrying capacities approved for your vehicle .
The recommended tire pressures for your Audi depend on the kind of
t ires on your vehicle and the num be r of passengers and/or amou nt o f
luggage you will be tra nspo rt ing .
The t ire pressure labe l is located on t he dr iver's side B-pilla r. The tire
pressure labe l lists th e recommended cold tire inflat ion p ress ures for

If you wish to improve comfort when operating the vehicle at
normal load (up to 3 o ccupants ), you can adjust tire pre ssures to
those specified for normal vehicle load . Before operating the
vehicle at maximum load, you must inc rease the tire pressures to
those specified for maximum vehicle load

Bear in mind that the tire press ure monitoring system* can on ly

B eca u se technical c hanges may be ma de to vehicle e quipment dur ing
the model year, always compare the tire s ize des ignation on the tire
pressu re la b el on yo ur vehicle with the t ires on your veh icle. Make
sure that the tire size in forma tion on the vehicle labe l is the same as
the s ize of the t ires on the vehicle. This is especially important i f the
vehicle belongs to someone else or you bought the vehicle with
different r ims/tires or you bought the vehicle as a previously owned
vehicle. that the vehicle can carry.

_& WARNING
Overloading a vehicle can cause loss of vehicle control , a cra sh or
other accident, serious personal injury, and even death .
• Carrying more weight than your vehicle wa s de signed to carr y
will prevent the veh icle from handling properly and increase the
risk of a los s of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe di stan ce.
• Tires on a vehicle that has been overloaded can fail suddenly
c ausing lo ss of control and a crash .
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
I
I
Remember, your safety and that of your passengers also depends on
m aki ng sure th at lo ad lim its are no t ex ceeded. Vehicle lo ad includes
everybody and everything in and on the veh icle. These load limits are
t echnically re fer red to as t he ve hicle's G ross Vehicle Weig ht Ra ting
("GVWR") . The Gross Axle Weight Rat ing ("GA WR") is the max imum
load that can be applied at each of the veh icle's two ax les. The Gross
Vehicle Weight Rat ing and the G ross Ax le We ight Ra ting are listed on
the safety comp liance sticke r label located on the driver's side B­
pillar. The tire p re ssur e label on your Audi lists the maxim um
combined weight of a ll of th e occ upants and luggage or other cargo
vehicle 's Gros s Vehicle Weight Rating. ._
