2016 AUDI A7 wheel alignment

Wheels
check the wheel alignment if
there is unusual wear.
- Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
The original tires on your vehicle have 1/16 inch (1.6 mm) high
"wear indicators" ~fig.
196 run­
ning across the tread . Marks on
the tire sidewall (for example
"TWI" or other symbols) indicate
the positions of the tread wear in­
dicators.
The t ires have reached the mini­
mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones ¢&..
Wheel rotation
Rotating the wheels regularly is
recommended to ensure the tires
wear evenly. To rotate wheels, in­
stall the wheels from the rear
axle on the front axle and vice ver­
sa. This will allow the tires to

have approximately the same
length of service life.
For unidirectional tires, make sure
the tires are installed according to
the running direction indicated on
the tire sidewall¢
page 259.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hid­
den . Unusual vibrations in the ve ­
hicle or pulling to one side may
indicate that there is tire damage.
Reduce your speed immediately .
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized repair facility to have the vehicle inspected.
&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can especially have a nega­
tive effect on handling, on the risk aquaplaning when driving
through water, when driving
