& 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 .
