Certification label
OBH059070
The certification label is located on the  
driver's door sill at the center pillar and 
shows the maximum allowable weight of 
the fully loaded vehicle. This is called the 
GVWR (Gross Vehicle Weight Rating). The 
GVWR includes the weight of the vehicle, 
all occupants, fuel and cargo. 
This label also tells you the maximum  
weight that can be supported by the 
front and rear axles, called Gross Axle 
Weight Rating (GAWR). 
The total weight of the vehicle, including  
all occupants, accessories, cargo, and 
trailer tongue load must not exceed the 
Gross Vehicle Weight Rating (GVWR) or 
the Gross Axle Weight Rating (GAWR). 
To find out the actual loads on your front 
and rear axles, you need to go to a weigh 
station and weigh your vehicle. Be sure 
to spread out your load equally on both 
sides of the centerline.
 WARNING
Overloading •	 Never exceed the GVWR for your  
vehicle, the GAWR for either the front 
or rear axle and vehicle capacity 
weight. Exceeding these ratings 
can affect your vehicle's handling 
and braking ability, and cause an 
accident.
•	 Do not overload your vehicle. 
Overloading your vehicle can cause 
heat buildup in your vehicle's tires 
and possible tire failure, increased 
stopping distances and poor vehicle 
handling-all of which may result in a 
crash.
NOTICE
Overloading your vehicle may cause  
damage. Repairs would not be covered 
by your warranty. Do not overload your 
vehicle.
 WARNING
If you carry items inside your vehicle  
(e.g., suitcases, tools, packages, or 
anything else), they are moving as fast 
as the vehicle. If you have to stop or 
turn quickly, or if there is a crash, the 
items will keep going and can cause 
an injury if they strike the driver or a 
passenger. •	 Put items in the cargo area of your  
vehicle. Try to spread the weight 
evenly.
•	 Do not stack items, like suitcases, 
inside the vehicle above the tops of 
the seats.
•	 Do not leave an unsecured child 
restraint in your vehicle.
•	 When you carry something inside the 
vehicle, secure it.

Curb weight 
This means the weight of a motor  
vehicle with standard and optional 
equipment including the maximum 
capacity of fuel, oil and coolant, but 
without passengers and cargo. 
DOT markings 
The DOT code includes the Tire  
Identification Number (TIN), an 
alphanumeric designator which can 
also identify the tire manufacturer, 
production plant, brand and date of 
production. 
GVWR 
Gross Vehicle Weight Rating 
GAWR FRT 
Gross Axle Weight Rating for the  
Front Axle. 
GAWR RR 
Gross Axle Weight Rating for the  
Rear axle. 
Intended outboard sidewall 
The side of an asymmetrical tire,  
that must always face outward when 
mounted on a vehicle. 
Kilopascal (kPa) 
The metric unit for air pressure. 
Light Truck (LT) tire 
A tire designated by its manufacturer  
as primarily intended for use on 
lightweight trucks or multipurpose 
passenger vehicles. 
Load ratings 
The maximum load that a tire is rated  
to carry for a given inflation pressure.
Load index 
An assigned number ranging from 1  
to 279 that corresponds to the load 
carrying capacity of a tire. 
Maximum inflation pressure 
The maximum air pressure to which  
a cold tire may be inflated. The 
maximum air pressure is molded 
onto the sidewall. 
Maximum load rating 
The load rating for a tire at the  
maximum permissible inflation 
pressure for that tire. 
Maximum loaded vehicle weight 
The sum of curb weight; accessory  
weight; vehicle capacity weight; and 
production options weight. 
Normal occupant weight 
The number of occupants a vehicle  
is designed to seat multiplied by 150 
pounds (68 kg). 
Occupant distribution 
Designated seating positions. 
Outward facing sidewall 
An asymmetrical tire has a particular  
side that faces outward when 
mounted on a vehicle. The outward 
facing sidewall bears white lettering 
or bears manufacturer, brand, and/or 
model name molding that is higher or deeper than the same moldings
