2009 AUDI Q7 tire type

Cleaning and protection -
----------------
•
Under certain circumstances, weekly washing may be necessary.
Under other conditions , a monthly washing and waxing may be
adequate .
After the winter, the
underside of the vehicle should be thoroughly
washed, preferably in a professional car wash.
& WARNING
Always read and heed all WARNINGS and other information
~ page 312. •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However, the
effect on the paint depends to a large extent on the design of the
facility, the filtering of the wash water , the type of wash and care
material, etc. If the paint has a dull appearance after going through
the car wash or is scratched , bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash .
Before going through a car wash, be sure to take the usual precau­
tions such as closing the windows and the Panoramic sliding
sunroof. Factory installed antennas must not be removed.
If you have installed additional accessories on the vehicle - such as
spoilers, roof rack, etc. -it is best to ask the car wash operator if
these should be removed .
& WARNING
Please take note of the following points before going through an
automatic car wash with your vehicle, so that you can avoid
damage to your vehicle.
& WARNING (continued)
• Compare the track of your vehicle with the distance between
the guide rails of the facility -there is a risk of damage to the
wheels and tires .
• Compare the height and width of your vehicle with the height
and width of the tunnel at the facility.
• Fold the exterior mirrors flat -there is a risk of damaging the
exterior mirrors. Power folding exterior mirrors* must not be
folded in or out by hand. Use the power function!
• Do not allow the wiper blade to fall onto the windshield after
the vehicle is dried -there is a risk of damaging the paint on the
hood.
• Always read and heed all WARNINGS and other information
~ page312. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
Before you start washing, make sure you have read and
understood the WARNINGS ::::>
& in "General informa­
tion" on page 312.
- First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work
your way down to the bottom, using a sponge, a sponge
glove or a clean brush.
Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt.
Rinse the car thoroughly with water.
Use a chamois leather to gently wipe the exterior dry.

Tires and wheels
Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particularly considering the comparative ly sma ll patch
of rubber on each tire that assures that all- important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regu lar ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avoiding dama ge
If you have to drive over a curb or similar obstacle, drive very slow ly
and as close as possible at a right angle to the curb.
A lways keep chemica ls includ ing grease, oil, gasoline and brake
f luid off the tires.
I nspec t the tires regularly for damage (cuts, cracks or blis ters, etc.l.
Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove them to indicate the direction of rota ­
tion . This ensu res you to be ab le to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
St ore t ires in a vertical posit ion if they a re not mounted on rims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in~&.
The tread dep th of new tires may va ry, according to the type and
make of tire and the tread pattern.
Hidden d ama ge
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or the vehicle pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immed iately by an authorized Audi dealer or qualified workshop .
Unidire ction al tir es
A unidirectio nal tire can be iden tif ied by arrows on the s idewa ll, that
point in the direction the tire is designed to rotate. You must follow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
~ page 379.
in. WARNING
Ne w tire s or tire s that are old , worn or damaged cann ot pro vide

• New tire s tend to be slippe ry and m ust be broken in . To redu ce
the risk of losing control, a colli sion and seriou s per sonal injurie s,
drive with speci al care for t he fi rst 350 m ile s ( 560 km l.

make, there will be six to eight of them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other symbols)
indicate the positions of the tread wear indicators. Worn tires must
be replaced. Different figures may apply in other countries=>& .
Tire pressure
Incorrect tire pressure causes premature wear and can cause
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month =>
page 353.
Driving style
Driving fast around curves, heavy acceleration and hard braking
increase tire wear.
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals. Please
remember the following:
• Tire rotation intervals may differ from the vehicle service inter­
vals outlined in your Warranty
& Maintenance booklet.
• The longer one tire is used in one location on the vehicle , the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer's suggested tire rotation intervals .
• Vehicles with front-wheel drive experience more tread wear on
the front wheels compared to all-wheel drive (quattro ®l.
• Please rotate tires as shown =>
page 357, fig. 294.
• Extra care must be taken when rotating direction-specific tires
=>
page 379.
Wheel balancing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unbal ­
anced, resulting in vibrations you can usually feel through the
steering wheel. Unbalanced
wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause excessive tire wear , impairing
the safety of the vehicle. If tires show excessive wear, have the
wheel alignment checked by an authorized Audi dealer or qualified
workshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size,
construction and tread type. For details see=>
page 294.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause tire damage, such as
grease, oil, gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old 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 are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

& WARN ING (continued )
• Never mount used tire s on your vehicle if you are not sure of
their "pre vious history. " Old used tire s may have been damaged
even though the damage cannot be seen that c an lead to sudden
tire f ailure and los s of vehicle control .
• All four wheels must be fitted with radial tires of the same type,
s ize (rolling circumference ) and the same tread pattern. Driv ing
with different tires reduces veh icle handling and can lead to a loss
of cont rol.
• If the spare tire is not the same as the tires that are mounted
on the vehicle • for e xample with winter tires · only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel a s soon as safely possible.
• Never drive faster than the maximum speed for whi ch the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build -up , sudden tire failure,
including a blowout and sudden deflation and lo ss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated.
• Fo r te chni cal reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehi cle model .
• If you install wheel trim di scs on the vehicle wheels , make sure
that the air flow to the brakes is not blo cked . Redu ced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicle s that were equipped
with them at the factory . The vehicle must have a chassis designed
for run flat tires and a factory -installed tire pressure monitoring
system that indi cates a loss of t ire pres sure . In corre ct u se of run
flat tires can lead to vehicle damage or accident s. Check with an
authorized Aud i dealer or tire specialist to see if your vehicle can
& WAR NING (continued )
be equipped with run flat tires . If run flat tires are used , they must
be installed on all four wheels . Mixing tire types is not permitted .
0 Note
• For tec hnical reas ons, it is not gen erally poss ible to use t he
whee l rims from other vehicles . T his can ho ld true for whee ls of the
sa me v ehicle type.
• I f the spare tire is different from the tires that you have mounted
o n yo ur vehicle ( for example wi nter tires or wide pro file tires), then
use the spare tire for a short period of time on ly and drive with extra
ca re. Replac e th e fl at t ire wi th the tire m atchi ng t he othe rs on you r
vehic le as soon as possib le .
• I f you should put different w heels and tires o n yo ur ve hic le (e. g.
winter wheels and t ires), you must be certain that the wheels and

Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C
Quality grades can be found where applicable on the tire side wall
between tread shoulder and maximum section width=>
page 359,
fig. 295.
For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require ­
ments in addition to these grades .
Tread wear
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled conditions on a specified
government test course .
For example, a tire graded 150 would wear one and
one half (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual condi­
tions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differ­
ences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B and C.
Those grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance => & .
Temperature
The temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissi­
pate heat when tested under controlled conditions on a specified
indoor 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 tire failure=>&.
The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law .
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or in combination, can
cause heat buildup 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 only be used in pairs and be installed on all four wheels .
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle .
Your vehicle is equipped with all -wheel drive, this will improve trac­
tion during winter driving, even with the standard tires. However,
we strongly recommend that you always equip all four wheels on .,_
