2009 AUDI Q7 tires

3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker=>
page 351, fig. 291.
4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo and luggage load capacity is 650 lbs. (1400-750 (5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely exceed the available cargo and luggage
load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred
to your vehicle. Consult this manual to determine how this reduces the avail­
able cargo and luggage load capacity of
your vehicle.

Tire service life
The service life of tires depends on a lot of different things
including proper installation and balancing, correct tire
pressure and driving style.

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. •

The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are specially matched to the char­ acteristics of the vehicle and can make a major contribution to good
road holding and safe handling when in good condition and prop­
erly 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 facilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about tech ­
nical 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 moni ­
toring system =>
page 361.
Always buy replacement radial tires that have the same specifica ­
tions as the tires approved for your vehicle by Audi. Replacement
tires must always have the same load rating specification as the original equipment or approved optional tires listed in the table
=> page 351.
Audi -approved specification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road-.,_

U.S. DOT Tire Identification Number (TIN) and tire
manufacture date
This is the tire's "serial number". It begins with the letters "DOT"
and indicates that the tire meets all federal standards . The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac ­
ture . For example, the numbers 2208 mean that the tire was
produced in the 22th week of 2008. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades~ page 363.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans ­
mits this information to the tire pressure monitoring system. If you
are going to replace the wheel rims on your vehicle, make sure the new rims also have these sensors
. The sensors must be compatible
with the tire pressure monitoring system on your vehicle.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system
will not work properly. In this case, the tire pressure monitoring
system would not be able to monitor the tire pressure or warn you
if it is necessary.
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho­
rized Audi dealer to replace lost valve stem caps .
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction 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
monitoring system indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring system, or some component of the
tire pressure monitoring system may be damaged.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision and serious personal injury.
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• 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 . .,.

& 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
t ires a re c omp atible with the tire pressure moni tor in g sys tem.
O therwise the system will register a malfunction and a fau lt

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 .,_

Summer tires provide less grip on ice and snow .
Winter tires (s now ti res) mus t always be fitted on a ll four whe els .
Compatible tire pressure monitoring sensors must be installed on

Ask your authorize d Audi dealer or qualified worksho p for permitted
winter tire sizes. Use on ly rad ial winter t ires .
Winter tires lose their effectiveness when the tread is worn down to a depth of 0 .157 inc h (4 m m).

& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed . Always know the maximum speed
before driving off . Never dr ive faster than the speed permitted for
your specific winter tires. This will cause damage to the tires
leading to an accident and serious personal injury to you and your
passengers .
& WARNING
Driving faster than the maximum speed for whi ch the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation , loss of control , crashes and serious
personal injuries. Have worn or damaged tires replaced immedi­
ately.
• Winter tires have maximum speed rating that may be lower
than your vehicle's maximum speed .
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated.
& WARNING
Always adjust your driving to the road and traffic conditions .
Never let the good acceleration of the winter tires and all -wheel
dr ive tempt you into taking extra risks . Always remember :
• When braking , an all -wheel drive vehicle handle s in the same
way as a front drive vehicle .
• Drive carefully and reduce your speed on icy and slippery roads,
even winter tires cannot help under black ice conditions .
