The Goodyear Tire & Rubber Company has introduced a new fuel-efficient commercial tire technology—Fuel Max—and three new tires for long-haul trucks that could deliver up to a 4% improvement in fuel economy, according to the company.
Actual Society of Automotive Engineers (SAE) test results of the tires driven at highway speeds showed an 8% improvement in vehicle fuel economy compared with standard Goodyear over-the-road tires.
Since no one drives at constant speed on flat terrain for a 10-hour shift, Goodyear engineers adjusted the SAE results to 4 percent to estimate real-world conditions, such as varying driver inputs, road conditions and terrain, and truck aerodynamics.
Improving a truck’s 6 mpg to 6.24 mpg with Fuel Max Technology could save around 770 gallons of fuel (assuming the truck is driven 120,000 miles per year). At the current US average diesel price of $3.03 per gallon, that represents $2,333 in savings.
From a return-on-investment perspective, the tire payback is virtually immediate.—Jon Bellissimo, Goodyear’s director of technology for commercial tires
The line includes new steer, drive and trailer tires and retreads for a complete tire system for trucking fleets and owner-operators.
The Fuel Max Technology uses a cool-running, dual-compound construction on the exterior of the tire to help reduce the amount of energy generated within the tread for lower rolling resistance.
Enhanced Casing Design (ECD) also helps reduce running temperatures and assists rust resistance. A uniquely shaped pressure distribution groove helped minimize shoulder wear, while a barrel-shaped footprint, edge blades and five-rib design offer even wear on the road surface of the tire.
