Uniform tire quality grading
- Tread wear
- Traction AA A B C
- T emperature ABC
Quality grades can be found where applicable
on the ti re side wa ll between tread shoulde r
and maximum section wid th ¢ page 193,
fig. 151 .
For example : Tread wear 200, Tract ion AA ,
Temperatu re A .
All passenger car tires must conform to Feder
al Safety Requi rements in addition to these
grad es.
Tread we ar
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a spec ified
government test course .
For example, a t ire graded 150 would wear
one and one half (1 1/2) t imes as well on the
government course as a tire graded 100 .
The relat ive perform a nee of ti res depends
upon the actua l conditions of their use, how
ever, and may depart sign ificantly from the
norm due to var iat ions in dr iv ing habits, serv
i ce practices and differences in road character
i stics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B and
C. Those grades represent the
tire's abil ity to stop on wet pavement as
measured unde r controlled cond it ions on
spec ified gove rnment test su rfaces of asphalt
and concrete . A tire ma rked C may h ave po or
t ra ction perfo rm ance¢ &..
Temp erature
The temperature grades are A (the h ighest),
B, and C, repr ese nting the t ire's resistance to
the gene rat io n of heat and its ab ility to dissi-
Tire s an d wheel s 197
pate heat when tested under controlled condi
tions on a specified indoor laboratory test
whee l.
Sustaine d high temperature can cause the
mater ia l of the tire to degenerate and red uce
tire life, and excessive tempe rat ure ca n lead
to s udden tire failure ¢ &. .
T he gr ade C correspon ds to a level of pe rform
ance which all passenger car tires must meet u nder the Federal Motor Vehicle Safety Stand
ard No . 109 . Grades Band A represent higher
l evels of performance on the laboratory test
whee l than the minimum requ ired by law.
A WARNING
The traction grade assigned to th is tire is
based on straight-ahead braking traction
tests, and does not include accele rat ion,
cor neri ng, hy droplaning or peak t ra ction
ch aracte rist ics.
A WARNING
T he temperature grade for this tire is es
tablishe d for a tire that is properly inf lated
and not overloaded . Excess ive speed, un
derinflation, or excessive loading, e it h er
separately or in combinat ion, can ca use
heat bui ldup and possible tire failure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F (7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true w inter or "snow" tires, those
with very deeply cut tread. T hese tires should
o nl y be used in pairs and be installed o n all
fou r wheels . Make sure you purchase snow
ti res that a re the same si ze and construction
type as the othe r ti res on you r vehicle.
If your vehicle is equipped w ith all-whee l
drive*, th is w ill improve traction during winter
driv ing, even with the s tanda rd tires . Howev-
er, we stro ngly recommend that you always ..,.

198 Tire s and wheel s
equip a ll four wheels on your vehicle with cor
rectly fitted winter tires or all-season tires,
when winter road conditions are expected .
This a lso improves the vehicle's braking per
formance and reduces stopping distances.
Summer tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must always be fitted
on all four whee ls .
Compat ible tire pressure mo nitor ing sensors
must be installed on all fo ur winter tires for
the tire pressure monitoring system to func
tion proper ly
i=;, poge 195 .
Ask your autho rized Aud i dea ler o r qualified
wo rkshop fo r permitted
winter tir e size s . Use
on ly radia l w inte r tires .
W inter t ires lose the ir effectiveness when the
tread is worn down to a depth of 0.157 inch
(4 mm) .
Only drive with wi nter tires under winter con
d itions . Summer tires hand le better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
Please always remembe r that w inte r tires may
have a lower speed rating than the t ires origi
na lly installed on your veh icle at the t ime i t
was manufactured. Please see
r=;, page 194 ,
Speed roting (letter code) for a list ing of the
speed rating letter codes and the maximum
speed at which the tires can be driven.
The speed ra ting lette r code
(i=;, poge 185) is
on the s ide wall of the tire
i=;, poge 193.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max
im um speed . Always know the maxim um
speed before driving off. Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
tires leading to an accident and serious
personal in ju ry to you and yo ur passen
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your veh icle
were designed can cause t ire failure in
cluding a blowout and sudden deflation,
l oss of cont ro l, crashes and ser ious per
sonal injuries. Have wo rn o r damaged ti res
r eplaced immedia tely.
- W inte r ti res have maxim um speed rating
tha t may be lower than your vehicle 's
maximum speed.
- Never drive fas ter than the speed for
which the win ter or othe r ti res installed
on yo ur vehicle are rated.
A WARNING ~
A lways ad just your driving to the road and
traffic condit ions. Never let the good ac
celeration o f the winter tires and a ll-wheel
drive tempt yo u into taking extra risks. Al
ways remember:
- When braking, an all-wheel drive veh icle
handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
~ For the sake of the environment
Use summer tires when weather condi
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
Snow cha ins may be fitted only to the rea r
whee ls, and o nly to certa in tire sizes . Ask your
autho rized Aud i dea le r o n whi ch t ire si zes
snow c hains ca n be used.
T he snow chains must have low-p rofile links
and must not be t hicker than 0 .53 inch
(13 .5 mm), in cl ud ing the lo ck.
Remove wheel center covers before putt ing
snow c ha ins on your vehicle
r=;, @ . For safety
reasons cover caps must then be f itted over

the wheel bolts. These are available from au
thorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi
cle or installing them incorrectly can in
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in
structions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer
tain roads, this normally also applies to ve
hicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
Tires and wheels 199
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 221.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor
que of the wheel bolts is too low, they
can loosen and come out when the vehi
cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be
come loose.
(D Note
The specified torque for the wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb( ± 10 Nm). Torque wheel bolts diago
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author
ized Audi dealer or qualified workshop.

soon as possible, and inflate them to the
proper pressure . Driving on a significant ly un
der-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation a l
so reduces fuel efficiency and tire tread l ife,
and may affect the veh icle 's handling and
stopping ab ility.
Please note that the TPMS is not a substitute
for proper t ire maintenance, and it is the dr iv
er's responsib ility to ma inta in correct t ire
p ress ure , even if under- inflation has not
reached the leve l to t rigger illumination of the
TPMS low tire pressure telltale .
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indicate when
the system is not ope rating properly. The
TPMS malfunc tion indica to r i s combined wi th
the low t ire pr essu re tellta le. When the sys
tem detec ts a ma lf u nct ion, the te lltale will
flash for approximately one minute and then remain continuo usly ill uminated . This se
q uence will continue upon subsequent vehicle
start-ups as long as the malfunction ex ists.
When the malfunction indicator is ill uminat
ed, the system may not be able to detect or
signa l low t ire pressure as intended . TPMS
malfunct ions may occ ur for a variety of rea
sons, including the ins talla tio n of replace

the TPMS to continue to function properly .
Introduction
The tire pressure monitoring system monitors
air pressure in all four road wheels while the
vehicle is moving .
As soon as the tire pressu re mo nitor ing sys
tem senses a s ignificant loss of a ir pressure in
one or severa l ti res, text messages and yellow
symbo ls appear in the instr ument cluster dis
p lay to alert the driver. The
[ti warning light
Tire s an d wheel s 201
in the instrument cluster comes on when the
ti re is significant ly underinflated .
T he wa rni ng lig ht
[ti also illu minates i n the
case of a system mal funct io n.
Be aware that t ire pressure is a lso dependent
o n the tempe ratu re of the t ire. For eve ry 18 ° F
(10 °C) incre ase in tir e te mper ature, tire pres
s u re inc reases by about 1.5 psi (0 .1 bar). The
ti re warms up while the ve hicle is moving and
tire p ress ure rises . So you sho uld ad just tire
pressure only when they a re
cold, when the
temperature of the tires is ro ughly the same
as the ambient a ir temperature.
In order to keep the tire press ure monito ring
system p roperly ca librated, t ire press ure on
all four tires sho uld be checked at regu lar in
terva ls.
The tire pressure is shown on the label located
on the dr iver's side B-pillar (v is ib le when the
door is open) .
A WARNING
When the tire pressure mo nitoring system
war ning light is lit , one o r m ore of your
tires is s ignificantly under-infla ted . You
shou ld stop and check your tires as soon as
pos sib le, and in flate t hem to the proper
p ress ure a s in dic ate d on the ve hicle's ti re
p ress ure lab el
¢page 187. Driving on a
significantly under -inflated ti re causes t he
tire to over heat and can lead to tire failure .
Under-inflat ion also is like ly to impair the
vehicle's handling and stopping ab ility.
@ For the sake of the environment
D riving wit h un der -inflated tires red uces
fuel efficiency an d tire t read life.
(D Tips
- E ach tire should be chec ked monthly
w hen the tem perature of the tires is
about the same as amb ient a ir tempera

(D Tips
After a tire repair, have the sealant bottle
replaced at a dealership. This restores full
functionality to the Tire Mobility System .
What should I be
aware of when
changing a tire?
Tires with unidirectional tread design
-
Tires with unidirectional tread design must be
mounted with their tread pattern pointed the
right direction.
A unidirectional tire can be identified by ar
rows on the sidewall, which point in the direc
tion of the rotation. You must follow the
specified direction of rotation. This is necessa
ry in order for these tires to develop their op
timum characteristics regarding grip, road
noise, wear, and hydroplaning .
