Tire direction marks
The tires listed below are direc-
tional. The tire sidewalls are
marked with arrows indicating the
rolling direction of the tire. If
mounted on the wrong side of the
vehicle, directional tires will per-

When replacing tires or wheels, tire pressure sensors must also be
installed. Tire pressure sensors can be installed in any of the following
three ways:
