Engineering:Gross trailer weight rating
From HandWiki
In motor vehicles, the gross trailer weight rating (GTWR) is the total mass of a road trailer that is loaded to capacity, including the weight of the trailer itself, plus fluids, and cargo, that a vehicle is rated to tow by the manufacturer. In the United States and Canada , the static tongue load, the weight of the trailer as measured at the trailer coupling, is generally recommended to be 10-15% of the GTWR. In the United States and Canada , there are four main weight classes of trailer hitches as defined by the Society of Automotive Engineers (SAE):
- Class I — rated to 2,000 pounds (907 kg)
- Class II — rated to 3,500 pounds (1,588 kg)
- Class III — rated to 5,000 pounds (2,268 kg)
- Class IV — rated to 10,000 pounds (4,536 kg)
