Wheels

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-
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. 192. The letters “TWI”
or triangles on the tire sidewall
indicate the location of the tread-
wear indicators.

D Obey any applicable regulations in the
country where the vehicle is being oper-
ated.
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.
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 Audi Service Fa-
cility to have the vehicle inspect-
ed.

AN WARNING
Tread that has worn too low or
uneven tread depths on the
tires can reduce driving safety.
This can increase the risk of an
accident because it has a nega-
tive effect on handling, driving
through curves, and braking,
and because it increases the

Removing a wheel
> Remove the top and bottom wheel bolts com-
pletely using the hex socket in the screwdriver
handle (in the vehicle tool kit) > fig. 204 and
place it on a clean surface.
> Install the alignment pins (from the vehicle
tool kit) by hand into the empty holes
> fig. 205.
> Remove the rest of the wheel bolts.
> Remove the wheel >(@). The alignment pins re-
main in the holes.
Installing a wheel
Read the directions on > page 276 when instal-
ling unidirectional tires.
> Slide the wheel on over the alignment pins
>©.
> Install the wheel bolts and tighten them gently
using the hex socket.
> Remove the alignment pins and also tighten
the remaining wheel bolts.
> Carefully lower the vehicle using the vehicle
jack*.
276
> 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.

ZA WARNING
— Read and follow the important information
and notes under > page 251.
— 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.

To benefit fully from the advantages of the uni-
directional tire design, you should replace faulty
tires as soon as possible and restore the correct
running direction on all of the tires.
> Reinstall the caps on the wheel bolts if necessa-
ry.
> Store the vehicle tool kit in its designated
place.
> Make sure that the wheel that was removed,
the vehicle tool kit, and the vehicle jack* are se-
curely stored in the luggage compartment
=> page 54.
