steering wheel AUDI TT 2013 Owner´s Manual

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
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
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

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.
Tire s an d wheel s 197
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 tire 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 designed to operate a t higher
loads and at higher inflat ion p ress ures than
the corresponding standar d tire. Extra load
ti res may be ident ified as "XL", "xl", "EXTRA
LOAD", or "RF" on the sidewall.
Gross Axle Weight Rating ("GAWR")
me ans the lo ad-ca rry ing capa city of a si ngle
axle system, measured a t the tire -ground in­
te rfaces.
Gross Vehicle Weight Rating ("GVWR ")
mea ns the maximum total loaded we ight of

206 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.
Fig. 144 Tire tread: tre ad wea r ind icators (TWI)
l --------- ---
Fig. 145 Rotating t ires for more ev en wea r
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 144 running across the tread. Depend­
i ng on the make, there will be six to eight of
them evenly p laced around the tire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different figures may apply in other countries
c::> & .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 202 .
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service interva ls outlined in your
Warranty
& Maintenance Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 145.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 22 7 .
Wheel balancing
The wheels on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A whee l must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle. If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop.
all-wheel drive
Vehicles with quattro ® mus t always have tires
of the same size, construction and tread type .

218 Tires and wheels
When it is not possible to continue
driving , even with run-flat tires?
-If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the
Tire Pr essure Monitoring System does
not work .
- If the tire has been severely damaged, in a
crash , for example. The tread can separate
from a damaged tire as the wheel turns, and
hit parts of the vehicle, such as the fuel tank
filler neck , fuel lines or brake lines.
- Do not continue driving if severe vibration occurs or if the tire starts to smoke because
the tire is running hot.
- Do not continue driving if damage to the
tire, such as cracks in the sidewall, appears.
A WARNING
Improper use of run-flat tires can cause
vehicle damage that can lead to loss of ve­
hicle control, a crash and serious personal
lnJUry.
- Run-flat tires can only be used with spe­
cial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire Pre­
ssu re Monit oring Sys tem.
- Always inspect a tire that has lost air to
make sure it is safe to drive with the tir e
in the run-flat mode.
- Never drive with run-flat tires that have
been damaged in a collision.
- Never drive with run-flat tires if heat
build-up causes the tire to give off
smoke.
- Never drive with run-flat tires if the vehi­
cle shakes or vibrates severely.
- Never drive with a run-flat tire that de­
velops sidewall cracks or other damage
wh ile in use .
-If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module.
(D Note
Run-flat tires have specia l characteristics
and requirements, that are very different
from conventional tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional wheel rims.
(D Tips
- If you are not able to cont inue driv ing
w ith run-flat tires, please seek professio­
nal assistance.
- Please contact your authorized Audi
dealer or Audi of America, Inc. if you
have questions about tires and rims .
Driving with run-flat tires
Applies to vehicles: wit h Run -flat tires
Handling characteristics change when tire
pressure is low .
Driving on tires with low tire pressure changes
the way a veh icle handles, particularly when
cornering and braking. The handling charac­
teristics of run-flat tires do not seem to
change a lot even when driving on low pres­
sure or in the run-flat mode . Nevertheless you
must still take spec ia l precautions when oper­
at ing a vehicle on run-flat tires when tire pres­
sure is low o r the tire(s) is flat:
.,. Th e Electronic Stabilization Control (ESC)
must be switched on.
.,. Never drive faster than SO mph (80 km/h)
q &_ .
.,. Plan ahead when driving and anticipate
what you will have to do considering traffic
and road conditions up ahead .
.,. Accelerate carefully.
.,. Avo id unnecessary and sudden steering and
brak ing maneuvers .
.,. Reduce your speed in plenty of time before
intersections, curves and other places where
you may have to react qu ickly.
Please see:

ble to continue driving, even with run-flat
tires?
