federal motor vehicle safety standards cargo carrying capacity 12 pages in english in this notice of proposed rulemaking nprm we nhtsa seek to address the problem of motor home and travel trailer overloading by proposing to amend the federal motor vehicle safety standard fmvss on tire selection and rims for motor vehicles other than passenger cars. we are also proposing a related amendment to our safety standard for tire selection and rims for light vehicles. we propose to require manufacturers of motor homes and travel trailers over 4 536kilograms 10 000 pounds gvwr to provide information to consumers in a label that is intended to inform the consumer about the vehicles cargo carrying capacity ccc . this information would be helpful both at the time the consumer is making a purchase decision and also as the consumer uses his or her vehicle. we also propose to require that the size of tires on the same motor homes and travel trailers be the same as the size of the tires listed on the tire information label required by the standard on tire selection and rims for motor vehicles other than passenger cars. we are limiting our ccc label to motor homes and travel trailers with a gvwr greater than 4 536 kilograms 10 000 pounds as these are the vehicles that have large open interior areas that consumers fill with cargo. recreational vehicles rv with gvwrs equal to or less than 4 536 kilograms 10 000 pounds will be required to have less detailed ccc information as a result of an amendment to the fmvss on tire selection and rims which becomes effective 1 september 2005. it should be noted that on 1 june 2007 the fmvss on tire selection and rims for motor vehicles other than passenger cars will apply to vehicles with a gvwr greater than 4 536 kilograms 10 000 pounds and the fmvss on tire selection and rims will apply to vehicles with a gvwr equal to or less than 4 536kilograms 10 000 pounds . it is our belief that this proposed rule complements the efforts of the recreational vehicle industry to provide consumers with information in order to hel reduce overloading motor homes and travel trailers. this rulemaking responds to a petition from ms. justine may. in addition this proposed rule would provide regulatory relief for dealers from a labeling requirement in the safety standard on tire selection and rims for light vehicles. the standards requirement may currently require dealers which add even small amounts of weight to re-label the vehicles. under the proposed amendment dealers that add weight in excess of 0.5 percent of the vehicles gross vehicle weight ratings would be required to disclose this extra weight on labels affixed to the vehicles. dealers could add lesser amounts of weight without needing to change or add labels
