Tires and wheels
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
A label on your vehicle shows how much 
weight it may properly carry. 
The Tire and Loading Information 
placard can be found on the driver’s 
door B-pillar. This placard tells you im-
portant 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 pressures for the original 
equipment tires on your vehicle.
The Certification label, also found on 
the driver’s door B-pillar tells you about 
the gross weight capacity of your vehi-
cle, 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.

Following is a discussion on how to work 
with the information contained on the 
placard with regards to loading your vehi-
cle.

Spare wheels may be mounted against the 
direction of rotation (spinning) even with a unidi-
rectional tire for temporary use only until the reg-
ular drive wheel has been repaired or replaced. 
Always observe and follow applicable temporary 
use restrictions and speed limitations indicated 
on the spare wheel.
