inflation AUDI TT 2013 Owner´s Manual

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
material 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
ard No.
109. G rades Band A represent h igher
l eve ls of perfo rmance on the laboratory tes t
wheel than the minimum required by law .
A WARNING
The traction grade assigned to this tire is
based on stra ight-ahead b raking traction
tests, and does not include acceleration,
cornering, hydroplan 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 211
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 or "snow" tires, those
with very deeply cut tread. These tires should
o nly be used in pairs and be installed on all
four wheels . Make sure you purchase snow
t ires that are the same size and construction
type as the other tires on your 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 standa rd tires. Howev­
er, we strongly recommend that you always
equip all fou r wheels o n your veh icle w ith cor­
rect ly fitted winter tires o r all-season t ires,
when winter road condit ions are expe cted .
T his also improves the veh icle's braking per ­
formance and reduces stopping distances.
Summe r tires provide less grip on ice 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 siz es. Use
only 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 207.
Please a lways remember that winter tires may
have a lower speed rating than the tires origi -
nally installed on your vehicle at the time it .,.

snow c hains are suitably cove red . Check
the position 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.
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of whee l bolts is matched to the
factory insta lled r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
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
i s the same model
¢ page 245.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile d riving if greased or
o iled, even if tig htened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 213
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. After changing a whee l, the tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 202, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.

or ridges on the road, part icu larly if the tire is
u nderinflated.
I n o rder to m inim ize the o ccurrence of impact
damage to the t ires of your vehicle, we recom­
mend that you observe the following precau ­
tions:
- Always maintain recommended infla tion
pressures. Check your t ire pressure every
2,000 miles (3,000
km) and add air if neces ­
sary .
- Drive carefu lly on roads with potholes, deep
gullies or ridges. The impact from driving
t h rough 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 ich could eventu­
ally cause t ire failure . If you be lieve that a
t ire may have been damaged, replace the
t ir e as soon as possible.
- T hese tires may wea r mo re quick ly than oth­
ers.
- Please a lso remember that, wh ile these t ires
deliver respons ive handling, they may ride
l ess comfortably and make mo re no ise than
other choices.
Reduced performance in winter /co ld
sea son condit ion s
All ti res a re des igned for certa in pu rposes.
The low aspect ratio, ultra high performance
tires originally installed on your vehicle are in­
tended for max imum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather condit ions. If
you dr ive under those circumstances, you
should equip your vehicle with all -season or
winter tires, which offer better traction under
those cond it ions. We suggest you use the rec­
ommended snow or all-season tires specified
fo r your vehi cle, or their eq uivalent. Refer to
q page 211
for more detailed infor­
mation regarding winter tires.
Tire pressure monitoring system
General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, incl uding the spare ( if provided),
sho uld be checked monthly when co ld and in­
flated to the inflation 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 i n­
flat ion p ressure label, you should dete rmine
the p roper t ire infla tion p ress ure fo r th ose
t i res.)
As an added safety feature, your ve hicle has
been equipped with a tire pressure mon itoring
system ( TPM S) tha t illum inates a low ti re
pressure tel ltale when one o r more of your
tires is significant ly under-inflated . Acco rding­
l y, when the low tire pressure telltale 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 un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflat ion al ­
so reduces fuel effic iency and tire tread life ,
and may affect the vehicle 's hand ling and
stopp ing abili ty.
Please note that the TPMS is not a substitute
for proper tire ma intenance, and it is the driv­
er's respons ibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low tire pressu 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 p roperly . Th e
T PMS ma lfunction indicator is combined w ith
t h e low tire pressure te lltale. When the sys­
tem detects a malfunction, the telltale will
flash for approximately one min ute and then ..,_

216 Tires and wheels
Inflate the tire pressure to the proper
pressure as indicated on the vehicle's tire
pressure label¢
page 200. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability .
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor ind i­
cator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle .
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or accidents
could also result.
- If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module .
@ Tips
-The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction .
- The tire pressure monitoring system on
your Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall ¢
page 207. We recom­
mend using these tir es.
Reset tire pressure monitoring system
(Stepl)
Applies to veh icles: w ith tire pressure monitoring system

for the cigarette lighter.
~ Switc h on the igni tion.
~ Move the switch @¢ fig. 156 on the e lec­
tric a ir pump
ll to posi tion I. After 5 mi­
nutes, tire pressure must have reached at
least 1.8 bar.
~ Switch the electric a ir pump off - switch in
position
0 . If the requ ired tire pressure of at
least 1.8 bar has not been reached, it is not
poss ible to make a repa ir with the tire seal ­
ant. Seek professional ass istance.
Disassembling Tire Mobility System
~ Remove the hose from the valve and pu ll
the plug out of the socket.
~ Screw the dust cap onto the valve.
~ Place the empty sealant bottle back in the
original packag ing and clip it in place under
the floor so that no tire sealant can run out
into the vehicle.
~ Place the elect ric air pump in the luggage
compartment for the time being.
~ Start driving right away so that the sealant
is distributed in the tire.
A WARNING
-Follow the manufacturer's safety instruc­
t ions on the deca l for the air pump and
the sealant bott le.
- If a t ire pressure of 1.8 bar cannot be
achieved after pump ing for 5 m inutes,
the tire is too severely damaged. Do not
continue to drive .
- Seek profess ional assistance if it is not
poss ible to repair the tire with the tire
sealant.
l ) The e lectr ic air pump s hould never r un for longer than
6 min utes.
What do I do now? 223
(D Tips
-Do not operate the electric air pump for
more than 6 minutes witho ut stopping,
otherwise it can overheat. When the a ir
pump has coo led down, you can continue
to use it.
- If sealant has escaped, allow it to dry,
then you can peel it off.
Final check
App lies to vehicles: wit h Tire Mobility System
After driving for a short distance, tire
pressure must be checked
~ After d riving for about 10 m inutes, stop
and check the tire pressure.
~ If tire pressure is still at leas t 1.3 bar, in­
flate the tire to specified pressure (see driv­
ers side B -pillar), drive to the next repair
shop and have the tire and the sealant bot­
tle replaced.
~ If tire pressure is less than 1.3 bar, the t ire
is too severely damaged. Do not cont inue to
drive . Seek professional assistance.
A WARNING
If t ire pressure is less than 1.3 bar after
driving for 10 minutes, the tire is too se­
ve rely damaged. Do not continue to drive.
Seek professional ass istance .
(D Tips
After a tire repair, have the sealant bottle
replaced at a dealership. This restores full
funct iona lity to the Tire Mobility System.
