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 abso­lutely necessary and drive
carefully when doing so.
-If you install wheel covers on
the vehicle, make sure they al­ low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.

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¢
fig. 181 for
the correct tire pressure based on vehicle load.
..correct the tire pressure if nec ­
essary .
.. Vehicles with Tire Pressure Mon­
itoring System*: store the modi­
fied tire pressure in the Infotain ­
ment system ¢
page 226.
.. Check the pressure in the emer­
gency tire* /spare t ire*. Always
maintain the maximum temper­
ature 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

Wheels
and follow the important safe­
ty precautions in
q page 219,
Tires and vehicle load limits.
-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.
@ For the sake of the environment
Tire pressure that is too low in­
creases fuel consumption.
(D Tips
Audi recommends using the
tire pressure specified for a normal load
q page 218 or for
a full load when the vehicle is
partially loaded .
Make sure that the tire designa­
tion on your tire matches the des­ ignation on the tire pressure label
and the tire pressure table.

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
gi vehicle and can lead to sudden ...... N
~ tire failure, including a blowout

and sudden deflation that can
cause the vehicle to crash.
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
Gross Vehicle Weight Rat­
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 plus maximum load. The maxi­
mum load includes the number of..,.

Wheels
and a special procedure. You must not 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, see ¢
page 229, After changing a
wheel .
-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 Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac­
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower 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 install ing wheels
q page 217.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 inch (4 mm). The character istics of winter
tires also decrease greatly 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
222
-
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 may be per­
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv­
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win­
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer 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 inch (13.5 mm) in height, includ­
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.

of snow, snow chain s can imp air handling and
damage the t ires, and t he chains will quickly be
destroyed.
A WARNING
Using incorrect snow chains or installing snow
chains incorrect ly can result in loss of vehicle
co ntrol, which increases the risk of an acc i­
dent .
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* first.
Use coated snow chains .
@ Tips
When using snow chains, it may be useful to
switch on sport mode

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra­
t io ti res. These t ires have been tho rough ly tested
a n d been se lected specifically fo r yo ur model for
t he ir superb performance, road feel and handling
under a variety o f driving conditions. Ask your au­
thor ized Audi dealer for more details .
The low aspect ratio of these t ires is indicated by
a numera l of
55 or l ess in the tire 's size designa ­
tion. The numera l represents the rat io o f the
tire's sidewall height in relat ion to its tread width
expressed in pe rcentage. Conventional t ires 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 imp roper inflat ion pres­
sure . It is therefore import ant that low a spect
ratio tires are infl ated to the specified pressure
and that the inflation pre ssure is regularl y
checked and mainta ined . Tire pre ssure s shoul d
be checked at least once a month and alwa ys
befor e a long t rip
¢ page 217.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi­
ly by impact with potho les, curbs, gull ies or
Wh eel s
ridges on the road, particular ly if the tire is un ­
deri nflated.
In orde r to min imi ze the occurrence of imp act
damage to the tires of yo ur vehicle, we recom­
mend that you observe the following preca u­
tions:
- Always ma intain recommended inflat io n pres­
sures. Check yo ur ti re pressure every 2,000
miles (3,000 km) and add air if necessary .
- Dr ive ca refully on roads w ith po tholes, deep
gullies or ridges . The impac t from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso cause
damage to your tires.
- After any impact, immediate 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 a lways
easy to see . Damage can lead to loss of air and
underinflation, wh ic h could eventually cause
tire fa ilure. If you believe that a tire may have
been damaged, replace the tire as soon as pos­
sib le.
- These tires may wear more quickly than others .
- Please also remember that, while these tires
delive r responsive ha ndling, they may ride less
comfortably a nd make more noise than other
choi ces.
Reduced perfo rmance in winter /cold se ason
conditions
All tires are des igned for certai n purposes. The
low aspect ratio, ultra high performance tires
o rigi na lly installed o n your veh icle are intended
f or maximum dry and wet road per formance 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 snow or all-season tires
spec ified for your veh icle, or their equiva lent .
