2011 AUDI R8 SPYDER fuel pressure

204 Tir es and whe els
eq uip all four wheels on your vehicle with cor ­
rectly fitted winter tires or all-season tires,
when winter road conditions are expected. This a lso improves the vehicle's braking per­
formance and reduces stopping distances.
Summer tires provide less grip on ice and
snow.
W inter t ires (snow t ires) must always be fitted
on all four wheels.
Compat ible tire pressure mon itor ing sensors
must be installed on all fou r winter tires for
the tire pressure monitoring system to func­
tion proper ly ~
page 201 .
Ask your authorized Aud i dea ler or qualified
wo rkshop for permitted
winter tir e sizes. Use
only radia l winter tires .
W inter t ires lose the ir effectiveness when the
tread is worn down to a depth of 0.157 inch
(4 mm) .
Only drive with winter tires under winter con­
d itions . Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
Please always remember that w inte r tires may
have a lower speed rating than the t ires origi­
na lly installed on your veh icle at the t ime i t
was manufactured. Please see
r:!> page 200 ,
Speed roting (letter code) for a list ing of the
speed rating letter codes and the maximum
speed at which the tires can be driven.
The speed ra ting letter code
(~ page 191) is
on the s ide wall of the tire
r::!> poge 199.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
im um speed . Always know the maxim um
speed before driving off. Never drive faster
than the speed permitted for your specific
w inte r tires . This will cause damage to the
tires leading to an accident and serious
personal in ju ry to you and your passen­
gers.
A WARNING
Driving faster than the maximum speed
for which the winter tires on your veh icle
were designed can cause t ire failure in­
cluding a blowout and sudden deflation,
l oss of cont ro l, crashes and ser ious per­
sonal injuries. Have wo rn o r damaged ti res
r eplaced immediately.
- W inte r ti res have maxim um speed rating
that may be lower than your vehicle 's
maximum speed.
- Never drive fas ter than the speed for
which the win ter or othe r ti res installed
on yo ur vehicle are rated.
A WARNING ~
A lways ad just your driving to the road and
traffic condit ions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks. Al­
ways remember:
- When braking, an all-wheel drive veh icle
handles in the same way as a front drive
veh icle.
- Drive carefully and reduce your speed on
icy and slippery roads, even w inter t ires
cannot help under black ice conditions .
~ For the sake of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
-
S now cha ins may be fitted only to the rea r
whee ls, and o nly to certa in tire sizes . Ask your
autho rized Aud i dea le r o n whi ch tire sizes
snow c hains ca n be used.
T he snow chains must have low-profile links
and must not be t hicker than 0 .53 inch
(13 .5 mm), in cl ud ing the lock.
Remove wheel center covers before putt ing
snow c ha ins on your vehicle~@ . For safety
reasons cover caps must then be f itted over

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
