STARTING AND OPERATING 183

If a tire does not have an arrow on the sidewall
indicating the direction of rotation, the wheel can be
mounted either way.
NOTE: The Tire Identification Number (TIN) must
always be visible on the outboard side of the tire.
Treadwear indicators (TWI) are required by law. These
indicators are located in six places on the tread
circumference and become visible at a tread depth of
approximately 1/16 in (1.6 mm), at which point the tire
is considered worn and should be replaced.
The treadwear indicator appears as a solid band across
the tread.
WARNING!
Spare wheels may be mounted against the direc-
tion of rotation (spinning) even with a unidirec-
tional tire for temporary use only until the regular
drive wheel has been repaired or replaced.
Always observe and follow applicable temporary
use restrictions and speed limitations indicated
on the spare wheel.
Have a spare wheel that was mounted against the
direction of rotation replaced with a regular road
wheel as soon as possible.
WARNING!
If you feel a sudden significant vibration or ride
distubance, or you suspect that possible 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
authorized Sprinter dealer or tire dealer for
repairs.
