Goodyear has introduced three new tires using a new fuel-efficient technology. The company’s new ‘Fuel Max’ design is focused on reducing both fuel and tire costs, while still delivering long tread life. The line includes new steer, drive, and trailer tires plus retreads for a complete “cradle-to-grave” tire system.

An 18-wheel tractor-trailer outfitted with these new tires could achieve up to 4% improved fuel economy, the company says, adding that test results, based on standard SAE procedures, actually showed an 8% improvement compared with standard Goodyear over-the-road tires. That was the result of extensive testing in a controlled environment — the new tires were driven at highway speeds at the Goodyear Proving Grounds in San Angelo, Texas. But since no one drives at constant speed on flat terrain for a 10-hour shift, the engineers adjusted the SAE results to 4% to estimate real-world conditions. At that rate, a truck getting 6.0 mpg would improve to 6.24 mpg, saving upwards of $3000 a year over 120,000 miles.

The new tires 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 is also offering UniCircle and precure retreading with Fuel Max Technology.

Features include four belts and the company’s ‘Enhanced Casing Design’.
