Tire service life
The service life of tires depends
on a lot of different things includ­
ing proper installation and bal ­
ancing, correct tire pressure and
driving style.
Fig. 149 Tire tread: tread wear indica ­
tors (TWI)
Tread Wear Indicator (TWI)
The original tires on your vehicle
have 1/16 inch (1 .6 mm) high
"wear indicators"c::>
fig. 149 run­
ning across the tread. Depending
on the make, there will be s ix to
eight of them evenly placed
around the tire. Marks on the tire
sidewall (for example "TWI" or
other symbols) indicate the posi­
tions of the tread wear indicators.
Worn tires must be replaced. Dif­
ferent figures may apply in other
countries c::>
.&..
Tire pressure
Incorrect tire pressure causes pre­
mature wear and can cause sud-
Tires and wheels
den tire blow-out. For this reason,
tire pressure must be checked at least once a month c::>
page 179.
Driving style
Driving fast around curves, heavy
acceleration and hard braking in­
crease tire wear.
Wheel balancing
The wheels on new vehicles are
balanced. However, various situa­
tions during everyday driving can
cause them to become unbal­
anced, resulting in vibrations you
can usually feel through the
steering wheel.
Unbalanced wheels must be reba­
lanced to avoid excessive wear on
steering, suspension and tires . A
wheel must also be rebalanced
when a new tire is installed .
Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, impair­
ing the safety of the vehicle. If
tires show excessive wear, have
the whee l alignment checked by
an authorized Audi dealer or
qualified workshop.

.&_ WARNING
-
Improper use of the vehicle jack can cause se-
rious personal injuries.

tighten wheel bo lts, since the bolts cannot
attain the necessary tightening torque if yo u
use the hex head, potentially causing an ac­
cident.
- The factory-supplied jack is intended only
for your veh icle model. Under no circum­
stances should it be used to
lift heavy
veh icles or other loads; you risk injuring
yourse lf.

ate stands if work is to be pe rformed under­
neath the vehicle; otherwise, the re is a po­
tential risk fo r injury.
