Tires
Warning!
If you feel a sudden significant vibration or
ride disturbance, or you suspect that possi-
ble damage to your vehicle has occurred,
you should turn on the hazard warning
flashers, carefully slow down, and drive with
caution to an area which is a safe distance
from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle or tires
appear unsafe, have the vehicle towed to
the nearest Mercedes-Benz Light Truck
Center or tire dealer for repairs.

Treadwear indicators (TWI) are required by
law. These indicators are located in six
places on the tread circumference and
G
become visible at a tread depth of
1
approximately
/
16
point the tire is considered worn and
should be replaced.
The treadwear indicator appears as a solid
band across the tread.
Warning!
Although the applicable federal motor
vehicle safety laws consider a tire to be
worn when the treadwear indicators (TWI)
become visible at approximately
1
/
in (1.6 mm), we recommend that you
16
do not allow your tires to wear down to
that level. As tread depth approaches
1
/
in (3 mm), the adhesion properties on
8
a wet road are sharply reduced.
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.
Specified tire inflation pressures must be
maintained. This applies particularly if the
tires are subjected to high loads (e.g. high
speeds, heavy loads, high ambient temper-
in (1.6 mm), at which
atures).
Warning!
Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
G
may lose control of the vehicle. Continued
driving with a flat tire or driving at high
speed with a flat tire will cause excessive
heat build-up and possibly a fire.
For more information, see "Tires and
wheels" ( page 373).
Hydroplaning
Depending on the depth of the water layer
on the road, hydroplaning may occur, even
at low speeds and with new tires. Reduce
vehicle speed, avoid track grooves in the
road and apply brakes cautiously in the
rain.
