Chevrolet engineers perform extensive testing for acceleration, handling, braking and thermal and structural performance to determine the Trailer Weight Rating (TWR) Gross and the Combination Weight Rating (GCWR) for our vehicles. The GCWR of the vehicle should not be exceeded when towing a trailer.

Chevrolet also calculates and publishes a Trailer Weight Rating (TWR) for each model or series for comparison purposes. The TWR is not specific to an individual vehicle and is most useful for comparing product lines to one another to select a vehicle that will meet towing needs. When matching up a customer to a vehicle, ensure that the total load (including passengers, cargo and equipment) they intend to pull weighs less than the TWR of the vehicle.

Because the TWR is calculated for a line of vehicles rather than an individual load situation, engineers have to make some standardized assumptions when calculating the TWR.

•First,engineersusethebasecurbweightofthat type of vehicle (the weight of a standard-equipped vehicle without any options).

•Second,engineersassumethatthereisonlyone person in the vehicle (the driver) who weighs 150 lbs.

•Third,engineersassumethereisacertaintongue weight for the load. A tongue weight is the weight of only the tongue of the loaded trailer.Forconventionaltrailering,engineersuse a tongue weight that is 10% of the loaded trailerweight.Forfifth-wheel/goosenecktrailering, engineers use a tongue weight that is 16.7% of the loaded trailer weight.

To be sure that the trailering combination is appropriate for a specific vehicle, the weight of the vehicle with all the optional equipment ordered must first be obtained. Once the weight is obtained, subtract the weight of the vehicle from the GCWR. The difference between the two is the capacity available for cargo, passengers, trailer, load and any other equipment. Put another way, GCWR should always be greater than or equal to the weight of the vehicle, passengers, cargo, trailer (with equipment) and load.

There are a couple of other ratings that are also important to making sure the trailering combination performs properly. It is important that the vehicle and the trailering combination do not exceed the tongue weight, Gross Vehicle Weight Rating (GVWR), or Rear Gross Axle Weight Rating (RGAWR) limitations for the vehicle. The only way to be sure it is not exceeding any of these ratings is to weigh the tow vehicle and trailer combination, fully loaded for the trip, getting individual weights for each of these items.

The tongue weight for a trailer is the downward force of the coupler of the trailer on the vehicle hitch. It can be calculated by placing the tongue of the trailer on an appropriate scale. Forconventionaltrailering,thetongueweightshould be between 10% and 15% of the loaded trailerweight.Forfifth-wheel/goosenecktrailering, the tongue weight should be between 15% and 25% of the loaded trailer weight.

The GVWR is the maximum amount the vehicle itself should weigh—including the as-equipped weight of the vehicle, plus the cargo, passengers and trailer tongue weight. Put another way, the GVWR should always be greater than or equal to the weight of the vehicle, passengers, cargo and tongue weight.

Finally,theRGAWR is the maximum allowable weight the rear axle can carry. A fully loaded vehicle with trailer can be weighed at a multi-platform weigh station to determine the weight on the rear axle of the vehicle to ensure that the RGAWR is not exceeded. Both the GVWR and the RGAWR information can be found on the certification/tirelabelwhichisfoundontherearedge of the driver door.

This chart is for use with a weight-distributing hitch. When using a weight-carrying hitch, the maximum trailer weight is 4000 lbs. with a 400-lb. tongue weight. A weight-distributing hitch-and-sway control is required for trailer weights greater than 4000 lbs. NOTES ON EXPRESS: Trailer tongue weight should be 10 percent to 15 percent of total loaded trailer weight (up to 1000 lbs.). Addition of trailer tongue weight cannot cause vehicle to exceed Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR). The standard base cooling system includes all content required to attain maximum trailer rating. No optional cooling equipment available. The Heavy-Duty Trailering Equipment Package (Z82) includes trailer hitch platform and 7-wire trailer wiring harness.

NOTES ON SILVERADO: Trailer tongue weight should be 10 to 15% of total loaded trailer weight. Trailer kingpin weight should be 15 to 25% of total loaded trailer weight. Addition of trailer tongue weight/trailer kingpin weight cannot cause vehicle weights to exceed Rear Gross Axle Weight Rating (RGAWR) or Gross Vehicle Weight Rating (GVWR). These ratings can be found on the certification label located on the driver door or doorframe. Fifth-wheel hitch is available as a dealer installed accessory on select models.

IMPORTANT INFORMATION ABOUT TRAILERING This information is intended to provide details about trailer ratings and provide a way to ensure that a vehicle is properly equipped to handle the load it is intended to pull.

Trailer Weight Ratings and Gross Combination Weight Ratings How to Keep the Load Within the Capabilities of the Vehicle

CHANGE IS COMINGSAE International (formerly the Society of

Automotive Engineers) has recently

announced some new guidelines for trailer

ratings. General Motors will therefore be

changing its ratings in the next few years.

GM has tested and prepared ratings to the

new SAE standard and is ready to

implement the new ratings when we can do

so without creating confusion about

comparisons of vehicles commonly used for

trailering. At this point, key competitors are

continuing to use their existing ratings for

2013 model year pickups, so we have

decided that retaining our existing rating

system for the 2013 model year will reduce

confusion for both dealers and customers.
