Direction of rotation
Unidirectional tires offer added advantages,
such as better hydroplaning performance. 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.
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 applica-
ble temporary use restrictions and speed lim-
itations indicated on the spare wheel.
Loading the vehicle
Two labels on your vehicle show how much
weight it may properly carry.
(1) The Tire and Loading Information placard
can be found on the driver’s door
B-pillar. This placard tells you important
information 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.
(2) The certification label, also found on the
driver’s door B-pillar. It tells you about the
gross weight capacity of your vehicle,
called the Gross Vehicle Weight Rating
(GVWR). The GVWR includes the weight
of the vehicle, all occupants, 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 allowable weight
that can be carried by a single axle (front
or rear). Never exceed the GVWR or
GAWR for either the front axle or rear
axle.
