Super Wides Best Duals in DOE Fuel Test

Michelin North America says that a new 383-page report by the Department of Energy’s Oak Ridge National Laboratory shows that super wide radial truck tires are more fuel-efficient than duals on heavy trucks.

The four-year test covered more than 700,000 miles by six instrumented tractors and 10 trailers, MNA said.

“If fleets and owner-operators needed more proof that wide singles can save fuel costs, look no further,” said David Stafford, COO of Michelin Americas Research Company. “This real-world field testing confirms what our engineers and designers have said since we launched the Michelin X One nine years ago – that replacing duals with wide single tires not only reduces rolling resistance and saves energy, but also reduces the amount of CO2 we put into the atmosphere.”

Data collected during the tests included instantaneous fuel consumption, speed, acceleration, gear, location, time of day and grade.

Oak Ridge researchers, MNA said, “found significant fuel efficiency improvement over dual tires when Michelin X Ones were in use – 6% overall and 10% with fully-loaded tractor-trailers.”
