Direction of rotation
Unidirectional tires offer added advan-
tages, such as better hydroplaning perfor-
mance. To benefit, however, you must
make sure the tires rotate in the direction
specified.
An arrow on the sidewall indicates the
intended direction of rotation (spinning) of
the tire.
Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
ț The Certification label (Example B),
found on the driver’s door B-pillar, tells
you about the gross weight capacity of
your vehicle, called the Gross Vehicle
Weight Rating (GVWR). The GVWR in-
cludes the weight of the vehicle, all oc-
cupants, fuel and cargo. The
Certification label also tells you about
the front and rear axle weight capacity,
called the Gross Axle Weight Rating
(GAWR). The GAWR is the total allow-
able weight that can be carried by a sin-
gle axle (front or rear). Never exceed
the GVWR or GAWR for either the front
axle or rear axle.
ț Depending on production date, some
vehicles may also be equipped with a
Tire and Loading Information placard
(Example A). This placard tells you
about the number of people that can be
in the vehicle and the total weight that
can be carried in the vehicle. It also
contains information on the proper size
and recommended tire inflation pres-
sures for the original equipment tires
on your vehicle.

Following is a discussion on how to work
with the information contained on the two
placards with regards to loading your
vehicle.

Spare wheels may be mounted against
the direction of rotation (spinning) even
with a unidirectional tire for temporary
use only until the regular drive wheel
has been repaired or replaced. Always
observe and follow applicable tempo-
rary use restrictions and speed limita-
tions indicated on the spare wheel.
