The Goodyear Tire & Rubber Co. announced a new commercial tire technology and three fuel-efficient linehaul tires that it said will deliver up to 4 percent improved truck fuel economy.

Featuring Fuel Max Technology, the line includes new steer, drive and trailer tires and retreads for a complete “cradle-to-grave” tire system for trucking fleets and owner-operators. Fuel Max Technology blends fuel efficiency with long tread life and performance, the company said.

While company officials are citing up to a 4 percent hike in fuel economy with the new tires, actual Society of Automotive Engineers test results showed an 8 percent improvement in fuel economy compared with standard Goodyear over-the-road tires.

“The test showed what our tires are capable of achieving in a controlled test environment,” said Jon Bellissimo, Goodyear’s director of technology for commercial tires. Following SAE test procedures, the new tires were driven at highway speeds at Goodyear Proving Grounds here to benchmark the performance of the Fuel Max Technology line compared to conventional Goodyear commercial tires. Because 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.

A 4 percent boost in fuel economy could mean significant savings for operators switching to Fuel Max Technology, Bellissimo said. Improving a truck’s 6 miles per gallon to 6.24 mpg saves up to $2,100 in fuel per year (assuming the truck is driven 120,000 miles per year and fuel costs $2.85 a gallon).

Goodyear tires featuring Fuel Max Technology include the Unisteel G395 LHS steer tire, Unisteel G305 LHD drive tire and Unisteel G316 LHT trail tire in standard (11R22.5) and low-profile (295/75R22.5 and 285/75R24.5) sizes. Goodyear also is offering UniCircle and precure retreading with Fuel Max Technology.
