2018 AUDI A6 wheel alignment

Wheels
-Only use tires that are more than six years old when abso­lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on your vehicle. Using them when not permitted can lead to
ve­
hicle damage or accidents.
-If you install wheel covers on the vehicle, make sure they al­low enough a ir circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage

Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
l) Obey any applicable regulations in your
country.

-Driving qu ickly through curves,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty 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 quick ly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion
c> fig . 186. The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators.
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
