206 Tires and wheels
conditions. Ask your authorized Audi dea ler
for more details.
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's size
designation. The numeral represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven
tional tires have a height/width ratio of 60 or
more.
The performance of low-aspect -ratio tires is
particularly sensitive to improper inflation
pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the inflation pressure is reg
ularly checked and mainta ined. Tire pressures
should be checked at least once a month and
a lways before a long t rip
~ page 195, Check
ing tire pressure.
What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
eas ily by impact with potholes, curbs, gullies
or ridge5 on the road, particu larly if the tire i5
underinflated.
I n order to minimize the occurrence of 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 air if neces
sary.
- Drive carefully 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
authori zed Audi dealer. Rep lace a damaged
tire as soon as possible.
- Inspect your tires 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 believe that a tire
may have been damaged, replace the
tire as soon as possib le.
- These tires may wear more quickly than oth
ers.
- Please also remember that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices .
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
t ir es originally installed on your vehicle are in
tended for maximum dry and wet road per
formance and handling . They are not suitable
for cold, snowy or icy weather conditions . If
you drive under those c ircumstances, you
should equ ip your vehicle w ith winter t ires,
which offer better traction under those condi
tions . We suggest yo u use the recommended
snow tires specified for your vehicle, or their
equivalent.
Refer to~
poge 203 for more detailed infor
mation regarding winter tires.
Ti re pressure
monitoring system
General notes
E ach tire, including the spare (if provided),
shou ld be checked monthly when cold and in
flated to the inflat ion pressure recommended
by the vehic le manufacturer on the vehicle
placard or tire inflation pressure label (If your
vehicle has tires of a different si ze than the
size indicated on the vehicle placard or tire in
flat ion pressure label, you should determine
the proper t ire in flation pressure for those
t ir es .) .
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. According
ly, when the low tire pressure telltale illumi
nates, you shou ld stop and check you r tires as
Ill>-
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 p ressu re tell ta le. When the sys
tem detec ts a malf unct ion, the te lltale will
flash for approximately one minute and then remain continuo usly ill uminated . This se
q uence will cont inue upon subsequent vehicle
start-ups as long as the ma lfunction 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 tion of replace
ment or alternate tires o r whee ls on the veh i
cle that prevent the TPMS from funct io ni ng
p roperly . Always check the TPMS malfunct ion
t ellta le afte r replacing one o r more t ires or
wheels o n your veh icle to ensure tha t the re
p lacemen t or a lternate tires and wheels allow
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 o f air 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
[al warning light
Tire s an d wheel s 207
in the instrument cluster comes on when the
ti re is significant ly underinflated
Q page 34.
The wa rni ng lig ht [al also illu minates i n the
case of a system mal fun ct 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 vehicle is moving and
ti re 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 roughly the same
as the ambient a ir temperature.
In order to keep the tire press ure monitoring
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 more 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 19 3. D riving 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
t u re and set to the recommended infla
tion pressure as specified on the tire
pressure label
