Wheel Load Rating

The load rating of a wheel, as determined by the wheel manufacturer, must never be exceeded. Manufacturers identify a wheel’s maximum load rating and tire diameter by checking the back of the wheel or with the wheel manufacturer. If the load rating is not available the wheel should not be used on the vehicle. Wheel load rating requirements are determined by dividing the vehicles heaviest gross axle weight rating by 2. The axle weight rating for most vehicles is shown on the identification label located on the driver’s side door jamb, gas tank door, truck lid or glove compartment.
