2011 AUDI R8 SPYDER technical specifications

-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 171
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob yo ur
engine of peak performance.
Q) Note
Damage or malfunction due to poor fue l
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fille r flap.
If the unlocking system should fail, you can
still open the flap manually -for detailed in ­
structions see ¢
page 173.
You can find the fuel tank capacity of your ve­ hicle in
Technical Data ¢ page 228.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your vehicle. For
more information about fuel specifications,
see ¢
page 170.
Your vehicle fue l tank has an on -board refue l­
ing vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protecting the environment,
please fo llow this refueling procedure careful­
ly.

200 Tires and wheels
contribution to good road holding and safe
handling when in good condition and properly
inflated
¢ ,& .
We recommend that all work on tires and
wheels be performed by an authorized Audi
dealer. They are familiar with recommended
procedures and have the necessary special
tools and spare parts as well as the proper fa­
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary
information about technical requirements for
installing or changing tires and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and
not individually (for example both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system
¢page 201.
Always buy replacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement tires
must always have the same load rating speci­
fication as the original equipment or approved optional tires listed in the table
¢page 193.
Audi-approved specification tires are specially
matched to your vehicle and its load limits,
and can contribute to the important road hold­
ing, driving characteristics, and safety of the
vehicle. The table(¢
page 193) lists specifica­
tions of the tires approved for the Audi mod­
els covered by your Owner's Literature .
The tire pressure label located on driver's side
B-pillar (
¢ page 193, fig. 151) lists the speci­
f ications of the original equipment tires in­
stalled on your vehicle at the time it was man­
ufactured.
Federal law requires tire manufacturers to
place standardized information on the side­
wall of all tires¢
fig. 153. This information
identifies and describes the fundamental
characteristics, the quality grade of the tire
and also provides a tire identification number for
safety standard certification and in case of
a recall.
Tire specifications
Knowledge of tire specifications makes it eas­
ier to choose the correct tires. Radial tires
have the tire specifications marked on the
sidewall, for example:
P235 / 35 R 18 91 Y
This contains the following information:
P Indicates the tire is for passenger cars
235 Nominal tire width in mm of the tire
from sidewall edge to sidewall edge. In general, the larger the number, the wider
the tire
35 Height/width ratio in percent (aspect ra-
tio)
R Tire construction: Radial
18 Rim diameter code (in inches)
91 Load rating code
Y Speed rating letter code
XL (or "xl", "EXTRA LOAD", or "RF") indicates
that the tire is a"Reinforced" or an "Extra
Load" tire
M+S (or "M/S") Indicates that the tire has
some mud and snow capability
The tires could also have the information of
direction of rotation¢
page 189.
Tire manufacturing date
The manufacturing date is also indicated on
the tire sidewall (possibly only on the
inner
side of the wheel):
"DOT ... 2210 ... " means, for example, that
the tire was produced in the 22nd week of 2010.
Speed rating (letter code)
The speed rating letter code on the wheels in­
dicates the maximum permissible road speeds
¢ .&. in Winter tires on page 204.
P up to 93 mph (150 km/h)
Q up to 99 mph (158 km/h)
R up to 106 mph (170 km/h)
S up to 110 mph (180 km/h)

202 Tir es and whee ls
The installation of replacement tires with
steel cord body plies in the tire sidewall may
cause ma lfunction of the tire pressure moni­
toring system, and is not recommended (cord material information in molded on the tire
sidewall) .
Always check your tire pressure monitoring
system indicator after replacing one or more
tires on your vehicle. If the tire pressure moni­
toring system indicator flashes, or is on, your
system is not work ing properly.
A WARNING
- Us ing incorrect or unmatched tires and/
or wheels or improper t ire and whee l
combinations can lead to loss of contro l,
co llision and serious persona l injury.
- Always use tires, rims and wheel bo lts
that meet the specifications of orig inal
factory-installed t ires or other combina ­
tions that have been specifically ap­
proved by the vehicle manufacturer .
- Tires age even if they are not being used and can fail su ddenly, especially at high
speeds. Tires that are more than 6 years
o ld can only be used in an emergency
and then with special care and at lower
speeds .
- Never mount used tires on your vehicle if
you a re not sure of their "previous histo­ ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- Only the wheel/tire s izes spec ified by the
manufactu rer may be used on veh icles
with all-wheel dr ive.
- Never drive faste r than the maxim um
speed for which the tires on your veh icle
are ra ted because tires that are driven
f aster than their rated speed can fail
sudden ly .
- Overloading ti res cause heat build-up,
sudden tire failure, incl uding a blowout
and sudden deflation and loss of control. -
Temperature grades apply to tires that
are properly inflated and not over or un­
derinflated.
- For technical reasons it is not always
possible to use wheels from other vehi­
cles -in some cases not even wheels
from the same veh icle model.
- Do not use run-flat tires on your vehicle.
Using run-flat t ires can lead to veh icle
damage or crashes .
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er veh icles . Th is can hold true for wheels
of the same vehicle type .
- If you should put different wheels and
tires on your veh icle (e.g . winter wheels
and tires), you must be certain that the
wheels and tires are compatible with the tire pressure monitoring system. Other ­
w ise the system will register a malfunc­
tion and a fau lt message w ill be dis­
played. For more information, contact
your authorized Audi dealer.
(D Note
- When installing new tires, be care ful not
to damage the va lves or tire pressure
monitoring system sensors.
- Never drive without the valve stem cap.
The va lves cou ld get damaged.
- If the sensors must be replaced, then
the valve must also be replaced at the
same time .
@ For the sake of the environment
Dispose of o ld tires in accordance with the
l ocal requirements .
@ Tips
Tires with the iden tificatio n "RO l" have
been specially matched with your A udi. We
r ecommend using on ly these tires because
they meet the highest standards regarding
safety and driving characteristics when used correctly . Your authorized Audi R8
