Wheel balancing
The w heels on new ve hicl es a re bala nced. However, v ario us sit uatio ns
dur ing everyday driving can cause them to become unba lanced,
re su lt ing in vibra tions yo u can usually fee l throug h the stee rin g

Unbalanced whee ls mus t be rebalanced to avoid excessive wear on
s t eer ing, suspension and t ir e s. A wheel must also b e rebalanced
w hen a new tire is installed.
Safety first
Incorrect wheel alignment
Incorrec t wheel a lignment can c ause excessive t ire wear, im pair ing
t he sa fety o f the ve hicle . If t ires s how exc essive wear, hav e the wheel
alignment checked by an author ized A udi dealer o r qualifie d wo rk ­
shop.
All Wheel Drive
Vehicles with quattro ® must a lways have tires of the same s ize,
constr uctio n an d trea d type . For details see ;:::,
page 258 .
& 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 ind icators .
• 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

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control , collis ion
and seriou s personal injury.
& WARNING (co ntinued )
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that have been specifically app roved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that a re 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
eventhoughthedamagecannotbeseenthatcanleadtosudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type , size (rolling circumference) and the same tread pattern.
Driving with different tires reduces vehicle handling and can lead
to a loss of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for example with winter tires - only use the spare
tire for a short period of time and drive with extra care . Refit the
no rmal road wheel as soon as safely possible .
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Ove rloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or underinflated.
• For technical rea sons it is not always possible to use wheels
from other vehicles- in some cases not even wheels from the same
vehicle model.
• If you install wheel trim discs on the veh icle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopp ing distances
and causing a colli sion.
