Transportation - Wider tires increase cargo load
Wide tires on tractor-trailers can reduce the weight of a rig, enabling additional cargo to be added without compromising fuel efficiency. That conclusion is drawn from an in-depth tractor-trailer performance study managed by Oak Ridge National Laboratory's Center for Transportation Analysis. The study focused on a 12-month monitoring of a special tractor-trailer fleet traveling more than 700,000 miles across most of the Eastern United States through different terrain and driving conditions. DOE's Office of FreedomCAR and Vehicle Technologies funded the study.
