tire pressure AUDI A4 2017 User Guide

&_ WARNING . -
-Only use tire/rim combina-tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles - in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more than six years old when abso­
lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
Wheels
cool the brake system. If they
do not, this could increase the
risk of an accident.
Tire wear/damage
Fig. 254 Tire profile: treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low or high can increase tire wear
considerably.
-Driving quickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear more quickly. .,..

Checking/correcting tire
pressure
Wheels
.. Check the tire pressure at least
once per month and also check it before every long drive .
.. Always check the tire pressure
when the tires are
cold. Do not
reduce the pressure if it increas­
es when the tires are warm.
.. Check the label
c:::> fig. 256 for
the correct tire pressure based on vehicle load .
.. correct the tire pressure if nec ­
essary .
.. store the new tire pressure in
the Infotainment system
c:::> page 336 .
.. Check the pressure in the spare
tire (compact spare tire)*. Al­
ways maintain the maximum
temperature that is specified for
the tire.
A WARNING
Always adapt the tire pressure
to your driving style and vehicle load.
-Overloading can lead to loss of vehicle control and increase
the risk of an accident. Read and follow the important safe­
ty precautions inc:::>

Wheels
-The tire must flex more if the tire pressure is too low or if
the vehicle speed or load are
too high . This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con­
trol.
-Incorrect tire pressure in­ creases tire wear and has a
negative effect on driving and
braking behavior, which in­
creases the risk of an accident.
(D Note
Replace lost valve caps to re­
duce the risk of damage to the
tire valves.
Tire pressure table
Please note that the information
contained in the following table
was correct at the time of print­
ing, and the information is sub­
ject to change. If there are differ­
ences between this information
and the tire pressures specified
on the label on the driver's side 8-pillar, always follow the specifica­
tion on the 8-pillar label
¢ page 327, fig. 255.
328
(i} For the sake of the environment
-Tire pressure that is too low
increases fuel consumption.
-Fuel consumption may also in­
crease when driving with the
comfort tire pressure is se­
lected .
(D Tips
Audi recommends using the
tire pressure specified for a
normal load

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden

Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's

ing
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids ..

bolts and a special procedure. You must never
repair or disassemble them ¢
.&..
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, refer to ¢
page 348, Finishing .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inter tires significantly improve the vehicle's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern) , summer tires provide less trac­
tion on ice and snow.
.,. Use winter t ires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lowe r with winter tires
q ,&. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after installing wheels
¢page 327.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .16 in (4 mm) . The characteristics of winter
tires also decrease great ly as the tire ages, re­
gardless of the remaining tread .
A WARNING
-Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
332
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires w ith the ~ symbol are permitted .
Snow chains
Snow cha ins not only improve the driving in win­
ter road condit ions, but also the braking.
.,. Only install snow chains on the
front wheels .
This applies a lso to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when driv­
ing with snow chains. Do not exceed 30 mph
(SO km/h) .
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi deale r or author­
ized Audi Service Facility to see if you may use
snow chains .
Use
fine-mesh snow chains. They must not add
more than 0.53 in (13 .5 mm) in height, including
the chain lock.
You must remove the snow chains on roads with­
out snow. Otherwise , you could impair driving
ability and damage the tires .

A WARNING ,~
Using incorrect snow chains or insta lling snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acc i­
dent.
(D Note
Snow chains can damage the r ims/wheel cov­
ers* if the chains come into d irect contact
w ith them. Remove the wheel covers* before­
hand . Use coated snow chains.

Low aspect ratio tires
Your Aud i is facto ry-equipped with low aspect ra ­
tio ti res. These t ires have been tho rough ly tested
and been se lected specifically for yo ur model for
their superb per formance, road feel and handling
under a variety of driving conditions. Ask your au­
thorized Audi dealer for more details .
The low aspect ratio of these t ires is indica ted by
a numera l of
55 or les s in the tire's size designa ­
tion. The numeral represents the ratio of the
tire's sidewall height in r elation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more.
The performan ce of low-aspect- ratio tire s is par­
ticularl y sensiti ve to improper inf lat ion pres­
sure . It is therefore impo rtant that low aspect
ratio tir e s are infl ated to the specified pressu re
and tha t the inflation pr essure is regularly
checked and maint ained . Tire pre ssure s should
be check ed at lea st once a month and alwa ys
b efore a long trip<=:>
page 32 7.
What you can do to a void tire and rim
damage
L ow aspect rat io tires can be damaged more easi­
l y by impact with potho les, cu rbs, gull ies or
r idges on the road, pa rtic ularly if the tire is un­
derinflated.
Wh eel s
In order to min imize the occurrence o f impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau ­
t ions:
- Always maintain recommended inflation pres ­
sures . Check your tire pressure every 2,000
m iles (3,000 km) and add air if necessary .
- Drive carefully on roads with potholes, deep
gu llies or ridges . The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest au­
thorized Audi dealer . Replace a damaged tire as
soon as possible .
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear. Damage is not always
easy to see . Damage can lead to loss of a ir and
underinflation, wh ich could eventually cause
tire fa ilu re . If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos­
sible.
= These tires may wear mo re quickly tha n others.
- Please also remember that , while these tires
de live r responsive ha nd ling, they may ride less
comfort ably and make more noise t han other
choices .
Reduced performance in w inter /cold season
conditions
All tires are des igned for certai n pu rposes. The
low aspect ratio, ultra high performance tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and handling. They are not suitable for co ld, snowy or
icy weather conditions. If you drive under those
c ircumstances, you should equip your vehicle
with all -season or winter tires, which offer better
tract ion under those conditions . We suggest you
use the recommended s now or a ll-season tires
spe cified for your vehicle, o r their equiva lent.
Refer
to <=:> page 332 for more detailed informa ­
t ion regard ing winter tires.
Uniform tire quality grad ing
- Tread wear
333

Wheels
-Traction AA A BC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
~ page 317, fig. 253.
For example: Tread wear 200, Traction AA, Tem ­
perature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov­
ernment test course.
For example, a tire graded 150 would wear one
and one half
(1 1/2) times as well on the govern ­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however , and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.
Traction
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 un­
der controlled conditions on specified govern ­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
~ .& .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­ rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failur e~ ,& .
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un-
334
der the Federal Motor Vehicle Safety Standa rd
No. 109. Grades Band A represent higher levels
of performance on the laboratory test wheel than
the minimum required by law.
A WARNING
,--
The traction grade assigned to this tire is
based on straight -ahead braking traction
tests, and does not include acceleration, cor­ nering, hydroplaning or peak traction charac­
teristics .
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat­
ed.
Tire pressure monitoring indicator
(l) General notes
-
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the veh icle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­ ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a

significantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-infla­
tion also reduces fue l eff ic iency and tire tread
life, and may affect the vehicle's hand ling and
stopping ab ility.
Please note that the TPMS is not a substitute for
proper tire ma intenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inflation has not reached the leve l
to tr igger illum inat io n of the TPMS low tire p res­
sure telltale .
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operat ing properly. The TPMS mal­
function ind icator is combined w ith the low tire
p ressure tellta le. Whe n the system detects a
malfunct ion, the te lltale will flash fo r approxi­
mate ly one m inute and then remain cont inuo usly
illum inated. This sequence will continue upon
subseq uent ve hicle start -ups as long as the ma l­
function exists.
When t he mal funct io n ind icator is ill umin ated,
the system may not be ab le to detec t or signal
l ow tire pressure as intended. TPMS ma lfunctions
may occur for a variety of reasons, incl uding the
installation of replacement or alternate t ires or
wheels on the vehicle that prevent the TPMS from functioning properly. Always check the
TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your ve hicle to ensu re
that the replacement or alte rnate ti res and
wheels a llow the TPMS to con tinue to func tion
p roperly.
If the Tire Pressure Monitoring System
indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system mo/function.
Using the ABS sensors, the tire pressure mo nitor ­
ing system compa res the tire tread circ umfe r­
ence an d vib ration cha racteristics of the individ u­
a l tires. If the pressure changes in one or more
tires, this is ind icated in the instrument cluster
