hand le, avoid ing damage from road ha za rds and regularly inspecting
tires for damage includ ing cuts, s lashes irregular wea r and ove rall
condi tion a re the mos t important th ings that you can do to help avoid
sudden t ire failure including tread separation and blowouts.
Avoiding damage
If you have to d rive ove r a cur b or sim ilar obstacle, d rive very slowly
and as close as possible at a rig ht angle to the curb .
Always keep chemicals incl ud ing grease, oil, gaso line and brake f luid

& WARNING
New tires or tires that are old , worn or damaged cannot provide

• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control, a collision and serious personal injuries, dri ve with special care for the first 350 miles (560 km).
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries . Have worn or damaged tires

Incorrect wheel alignment
In correct whee l al ignme nt can ca use excessive tir e wea r, impairing
th e sa fety o f the vehicl e. If t ires show excessive w ear, hav e the w heel
alignment checked by a n authorized A udi dea ler or qualifie d work­
shop.
All Wheel Drive
Vehicles wi th quattro® must always have tires of the same size ,
con st ruct ion an d tread type . For details see~
page 194.
& WARNING
Sudden tire failure can lead to los s of control, a cra sh 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 t ire 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 failu re and loss of vehicle control. •

& WARNING (conti nu ed )
ev en though the damage cannot be seen that can lead to sudden
tire failure and lo ss of vehicl e control.
• All four wheels must be fitted with radial tires of the same
type, size (rolling circumference ) and the same tread patte rn .
Driving with different tires reduces vehicle handling and can lead
to a los s of control.
• If the spare t ire 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 e xtra care. Refit the
normal road wheel as soon a s safely possible.
• Never drive faster than the maximum speed for which the ti res
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s cau se 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 o ver or underinflated.
• For technical reasons it is not always possible to use wheels
from other vehicle s- in some cases not even wheels from the same
vehicle model.
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked. Reduced airflow to
the brakes can them to overheat , increa sing stopping distance s
and causing a collision.
• Run flat tires may only be used on vehicles that were equipped
with them at the factory. The vehicle must have a chassis designed
for run flat tires and a factory-in stalled tire pres sure monitoring
sy stem* that indicates a loss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or accidents. Check with an
authorized Audi dealer or tire speciali st to see if your vehicle can
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 .

vehicle type .
• If the spa re tire is different from the tires t hat you have mounte d
on you r vehi cle (fo r exa mple w inte r tir es or wide profi le tires), then

c are. Replace t he f lat tire w it h t he ti re m atch ing t he ot hers on yo ur
vehicle as soon as possible.
• If you put diffe rent whee ls and t ires o n your ve hicle (e.g . winter
w heels and tires), yo u must be certain t hat the whee ls and tires are
