wheel AUDI A5 COUPE 2014 Workshop Manual

Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi­
cle. If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop .
All wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see
~page 185 .
.8_ WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire 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 "hydroplaning" and toss of
control.
- 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
speeds .
- Never mount used tires on your vehicle if
you 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.

inflated
¢ ,& .
We recommend that all work on tires and
wheels be perfo rmed by an authorized Audi
dea ler. They are familiar with recommended
proced ures and have the necessary spec ial
too ls and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
Re placing t ires and whe els
Tires sho uld be rep laced at least in pairs and
not individua lly (for examp le both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system*
¢page 240.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement t ires
must always have the same load rating speci­
fication as the original equipment or approved
optional tires listed in the table
c:> page 226.
Aud i-approved specification ti res are specially
matched to your vehicle and its load limits,
and can contribute to the important road ho ld­
ing, driving characteristics, and safety of the
vehicle. The table
(c:>page 226) lists spec ifica­
tions of the tires approved for the Audi mod­
els covered by your Owner's Literature .

This is the t ire's "serial number". It begins
with the letters "DOT" and indicates that the
tire meets all federal 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 .
F or example, the numbers 2213 mean that
the t ire was produced in the 22nd wee k of
20 13. The othe r numbe rs a re mar ke ting co­
des that may or may not be used by the tire
manufacturer . This information is used to con­
tact consumers if a tire defect requires a re ­
call.
Audi Original tir e
Tires with the identi fication "AO" or "RO" have
been specia lly matched with your Audi . We
recommend using only t hese tires because
they meet the highest standards regard ing
safety and driving character istics when used
correctly . You r authorized Audi dealer will
g lad ly provide you with more information .
Tire ply composition and materi als used
The number of plies indicates the n umber of

A WARNING ~
- Using incorrect or unmatched tires and/
or wheels or improper tire and wheel
comb inat ions can lead to loss of control,
col lis ion and serious personal injury.
-Always use t ires, rims and whee l bolts
that meet the specif ications of original
factory- installed tires or other combina­
tions that have been specifically ap­
proved by the vehicle manufacture r.
- T ires age even if they are not being used
and can fai l sudden ly, especially at high
speeds. Tir es that are more than 6 yea rs
old can only be used in an emergency
a nd then w ith speci al care and at lower
speeds.
- Never mo unt used tires on your veh icle if
you are not sure of the ir "previous histo­
ry." O ld used tires may have been dam ­
aged even thoug h the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.

236 Tire s and whee ls
- All four wheels must be fitted with radia l
t ires of th e same ty pe, size (r olling c ir­
cumfe rence) and the same tread pattern.
Dr iv in g with different tires reduces veh i­
cle handling and can lead to a loss of
c o ntrol.
- If the spare tire is not the same as the
t ires that are mounted on the veh icle -
for example with winter tires - on ly use
the spare tire for a short period of time
and dr ive with extra care. Refit the no r­
ma l road whee l as soon as safely possi ­
ble.
- Never drive faster than the maxim um
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
sudden ly.
- Overloading ti res cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades app ly to tires that
are properly inflated and not over or un­
derinflated.
- For technical reasons it is not a lways
poss ible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel tr im discs on the ve­
hicle whee ls, make sure that the air flow
to the brakes is not blocked . Reduced air­
flow to the brakes can them to overheat,
increasing stopping d istances and caus­
ing a collision.
- Run flat t ires may on ly be used on
vehicles that we re eq uipped w ith them
at the factory. The vehicle must have a
chassis des igned for r un flat t ires and a
factory-installed tire press ure monito r­
ing system * that indicates a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dea ler or
t ire spec ialist to see if you r vehicle can be
equipped with run flat tires .
If run flat
t ires a re used, they must be insta lled on
all four wheels. M ixing tire types is not
permitted.
(D Note
- For technical reasons, it is not generally
poss ible to use the wheel rims from oth­
er veh icles. T his can hold tr ue for wheels
of the same vehicle type.
- If the spare tire is different from the tires that you have mounted on your ve­
hicle (for example winter tires or wide
profi le tires), then use the spare tire for a
short period of time only and drive w ith
extra care. Replace the flat tire w it h the
ti re mat ching the othe rs on your vehicle
as soon as possi ble.
- Never d rive without the valve stem cap.
The v alves co uld get damaged.
@ For the sake of the environment
Dispose of o ld tires in accordance w ith the
l ocal requirements.
Uniform tire quality grading
- Tread wear
- Tra ction AA A B (
- Temperature ABC
Quality grades can be found where applicable
on the t ire s ide wall between tread shoulder
and maximum section width
c> page 233,
fig . 172 .
For e xample: Tread wear 200 , Traction AA ,
Temperature A .
All passenger car ti res must conform to Feder­
al Safety Requirements in add ition to these
grades .
Tread w ear
The tread wear g rade is a comparative rating
based on the wear rate of the tire when tested
u nder contro lled conditions on a specified
government test course.
F o r example, a tire graded 1S0 wo uld wear
one and one ha lf (11/2) times as well on the
government course as a ti re graded 100. ..,_

The relative 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 iving habits, serv­
ice practices and differences in road character­
istics and climate .
Trac tion
The traction grades, from highest to lowest,
are AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as measured under controlled cond itions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢,&. .
Temp erature
The temperature grades are A (the h ighest),
B, and
C, representing the t ire's resistance to
the generat ion of heat and its ability to dissi ­
pate heat when tested under controlled condi­
tions on a specified i ndoor laboratory test
wheel.
Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden ti re fa ilu re ¢ ,&. .
The grade
C corresponds to a level of perform ­
ance which all passenger car tires must meet
u nder the Federa l Moto r Veh icle Safety Stand­
a rd No.
1 09. G rades Band A represent h igher
l eve ls of perfo rmance on the laboratory tes t
wheel than the m inimum required by law .
A WARNING
The traction grade assigned to this ti re is
based on stra ight-ahead b raking t raction
tests, and does not include acceleration,
cornering, hydrop lan ing or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es­
tablished for a t ire that is p roperly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
-
Tire s an d wheel s 237
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 winter o r "snow" tires, those
with very deeply cut tread. These tires should
o nly be used in pairs and be installed o n all
four wheels . Make sure you purchase snow
t ires that are the same size and construction
type as the other tires on you r vehicle.
Your vehicle is equipped with all wheel drive,
th is w ill improve traction during winter driv­
i ng, even with the standa rd tires . However, we
strong ly recommend that you always equip all
fo ur wheels on you r vehicle wit h corre ct ly fit­
ted winter tires or all-season t ires, when win­
te r road cond itions are expected . This also im ­
proves the veh icle's braking per formance and
reduces stopping dista nces.
Summe r tires provide less grip on i ce and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur wheels .
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire size s. Use
o nly rad ial w inter t ires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0 .157 inch
(4 mm) .
Only drive w ith w inter t ires under w inter con­
dit ions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat tire, see notes on spare
whee l
¢page 233.
Please a lways remember that winter tires may
have a lowe r speed rating than the tires o rigi -
nally installed on your vehicle at the time it .,.

was manufactured . Please see q page 234,
Speed roting (letter code) for
a listing of the
speed rat ing letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code( ¢
page 225) is
on the side wall of the tire
c::> page 233.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inter t ires. This will cause damage to the
tires leading to an accident and serious
personal inj ury to you and your passen­
gers.
A WARNING
=
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire failure in­ cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immed iately .
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed on your vehicle are rated.
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all whee l
drive tempt you into taking extra r is ks . A l­
ways remember :
- When brak ing , an a ll whee l drive vehicle
hand les in the same way as
a front drive
vehicle.
- Drive caref ully and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
{® Fo r the s ake of the en vironment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be f itted only to the front
wheels, and only to certain tire sizes . Ask your
authorized Aud i dealer on which tire sizes
snow chains can be used.
The snow chains must have low-prof ile links
and must not be th icker than 0.53 inch
(13 .5 mm), includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow chains on your vehicle
c::> @ . For safety reasons cover caps must then
be fitted over the wheel bolts . These are avail­
able from autho rized Aud i dealers.
A WARNING
Using the wrong snow chai ns for your veh i­
cle or instal ling them incorrect ly can in­
crease the risk of loss of cont ro l 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 specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before dr iv ing 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 whee l rim, can scratch or
damage it . Therefore, make sure that the
snow chains are s uitably covered. Check
the pos ition of the snow chains after

driving a few yards and correct if neces­
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this norma lly also applies to
veh icles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit ­
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model<=>
page 266.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop­
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 239
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) w ith a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i­
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k­
shop .
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
tions . Ask your authorized Aud i dealer for
more details .
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s­
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 228 , Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.

24 0 T ire s and wheel s
In o rder to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom­ mend that you observe the following precau­
tions :
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary.
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ire as soon as possible .
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and underinflation, wh ic h could event u­
ally cause t ire fail ure.
If you be lieve that a
ti re may have been damaged, replace the
tire as soon as possible.
- These tires may wea r more qui ck ly than oth­
ers.
- Please a lso remembe r that, whi le these t ires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices.
R educed p erf ormance in winter /cold
s ea son condit ions
A ll tires are designed for certain purposes .
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
f ormance and handling . They are not suitable
for cold, snowy or icy weather cond it ions.
If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, which offe r better traction under
those cond it ions . We suggest you use the rec­
ommended snow or a ll-season tires specified
for your vehicle, or their equiva lent .

Tire pressure
monitoring system
ill General notes
Applies to veh icles: w ith tire pressure monito ring system
Each tire, incl uding the spare (if provided),
sho uld be checked monthly when co ld and in­
flated to the inf lation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the
s ize indicated on the vehicle placard or tire in­
flat io n pressu re label, you shou ld dete rmine
the p roper t ire infla tion p ressure fo r those
t ir es) .
As an added safety feature, your veh icle has
been equipped with a tire pressure mon itoring
system ( TPM S) that illum inates a low ti re
pressure te lltale whe n one or more o f you r
tires is significant ly under -inflated . Acco rding­
ly, when the low tire pressure te lltale i llumi­
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly u n­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under -inflation al ­
so reduces fuel eff ic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respo nsibility to maintain co rrect tire
pressure, even if under -inflation has not
reached the leve l to tr igger illuminat ion of the
T PMS low tire p ressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate when
the sys tem is not operating properly . T he
T PMS ma lfunction indicator is combined with
the low tire pressure te lltale. Whe n the sys­
tem detects a malfunction, the telltale will
flash for approximately one min ute and then
rema in con tinuously illum inated . T hi s se­
quence will continue upon subsequent vehicle
start-ups as long as t he malfunct ion exists . .,.

When the malfunction indicator is illuminat­
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, including the installation of replace­
ment or alternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the T PMS malfunct ion
tellta le afte r replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacemen t or a lternate tires and wheels allow
the TPMS to continue to function properly .
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
Fig. 173 Display : underinflatio n warning
Using the ABS sensors, the tire pressure moni­
toring system compares the t ire tread circum­
