aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the

Glossary of tire and loading terminology
Accessory weight means the comb ined weight (in excess of
those sta ndard items which may be rep laced)
of au toma tic transmission, power steer ing ,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip
ment (whether installed or not) .
Aspect ratio
means the rat io o f the height to the w idth of
the tire in percent . Numbers of 55 or lower in
dicate a low sidewall for improved steering re
sponse and better overa ll handling on dry
pavement .
Bead
means the part of the t ire t hat is made o f
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead .
Cord means the strands forming the plies in the
tire.

typica l in those seasons . Aud i recommends
using winter tires during the winter
months . Low temperatures signif icant ly
dec rease the e lasticity of summer t ires,
which affects tract ion and brak ing ability.
If summer t ires are used i n very co ld tem
peratures, cracks ca n form o n the tread
bars , res ulting in perma nen t tire damage
that can cause loud driving noise and un
bala nced ti re s. Audi i s not respon sible for
th is type of damage .
Cold tire inflation pressure
means the t ire p ress ure recommended by t he
vehicle manufacture r fo r a tire o f a des ignated
s ize t hat has not bee n driven for more than a
coup le o f miles (k ilometers) at low speeds in
the three hour period before the tire press ure
is m easured or adjusted.
Curb weight
me ans the we ight of a motor ve hicle with
st andard equipmen t incl ud ing the max imum
capacity of fuel, oi l, and coolant, air condi
tioning and additional weig ht of optiona l
equipment.
Extra load tire
means a t ire design to oper ate a t higher load s
and at higher inflation pressures than the cor
responding standa rd tire . Extra load tires may
be identified as "XL", "x l", "EXTRA LOAD", o r
"RF" on the sidewal l.
Gross Axle Weight Rating ("GAWR")
me ans the load-ca rry ing capac ity of a single
axle system , measured at the tire -ground in
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
mea ns the maximum total loaded we ight of
the ve hicl e. .,..

unbalanced, resulting in vib rations you can
usually feel through the steering wheel.
Unba lanced wheels mus t be rebalanced to
avoid excessive wea r on s teer ing, suspens ion
and tires. A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Inco rrect whee l alignment can cause exces
sive tire wea r, impair ing t he safety of the veh i
cle. If t ires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All-wheel d rive
Ve hicles w it h quattro must always have tires
of the s ame s ize, construction and tread type.

A WARNING
Sudden tire failure can lead to loss of con
trol, a crash and serious persona l injury!
- Never drive a veh icle when the tread on
any t ire is worn down to the wear indica
tors.
- Worn tires are a safety hazard , they do
not grip well on wet roads and increase
your risk of"hydrop lan ing" and loss of
co ntrol.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
sp eeds.
- Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo
ry." Old used ti res may have been dam
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss o f vehicle control.
