Tire wear
Check the tires regularly for wear.
—Inflation pressure that is too low
or high can increase tire wear
considerably.
—Driving quickly through curves,
rapid acceleration, and heavy
braking increase tire wear.
—Have an authorized Audi dealer
or authorized Audi Service Facili-


) Obey any applicable regulations in the
country where the vehicle is being oper-
ated.

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 quickly.
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 > fig. 190. The letters “TWI”
or triangles on the tire sidewall
indicate the location of the tread-
wear indicators.
The tires have reached the mini-
mum tread depth !) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones > A.
Tire rotation
Rotating the tires regularly is rec-
ommended to ensure the tires
wear evenly. To rotate the tires, >

Removing a wheel
> Remove the top wheel bolt completely using
the hex socket in the screwdriver handle from
the vehicle tool kit > fig. 203 and place it ona
clean surface.
> Then install the alignment pin from the vehicle
tool kit by hand in the empty wheel bolt hole
> fig. 204”,
> Remove the rest of the wheel bolts.
> Remove the wheel >(). The alignment pin re-
mains in the hole while doing this.

D Applies to: vehicles with ceramic brake rotors*: Use a sec-
ond alignment pin* from the vehicle tool kit for the lowest
hole according to the steps described for the first align-
ment pin.
Installing a wheel
Read the directions on > page 321 when instal-
ling unidirectional tires.
> Slide the wheel on over the alignment pin >@.
> Install the wheel bolts and tighten them gently
using the hex socket.
> Remove the alignment pin and tighten the re-
maining wheel bolt.
> Carefully lower the vehicle using the vehicle
jack*.
> Tighten the wheel bolts in a diagonal pattern
using the wheel wrench.
The wheel bolts must be clean and loosen and
tighten easily. Check the contact surfaces for the
wheel and hub. Contaminants on these surfaces
must be removed before installing the wheel.

Z\ WARNING
— Read and follow the important information
and notes under > page 296.
— Never use the hex socket in the screwdriver
handle to tighten the wheel bolts. Using the
hex
socket will not achieve the required
tightening torque, which increases the risk
of an accident.
@) Note
When removing or installing the wheel, the
rim could hit the brake rotor and damage the
rotor. Work carefully and have a second per-
son help you.
Unidirectional tires
A unidirectional tire profile is identified by arrows
on the tire sidewall that point in the running di-
rection. You must always maintain the specified
running direction. This is necessary to ensure the
tire's optimal performance in regard to adhesion,
running noise, and friction, and to reduce the risk
of hydroplaning. >
