New Firestone Tires Carry More Weight At Low Pressure

Firestone’s Advanced Deflection Design (AD2) technology provides greater sidewall flexibility on its large farm tires. The company says tires with AD2 technology can carry a load up to 20 per cent greater than standard radials of the same size.

“That means the operator can carry heavier loads or add ballast to a tractor without having to raise air pressure in the tires,” says Tom Rodgers, director of marketing for Bridgestone Americas Agricultural Group. “Alternatively, they can carry the same weight at lower inflation pressures to reduce soil compaction.”

“Tractors continue to increase in size and power. These large, higher-horsepower machines require more ballast to put that increased power to the ground,” says Rodgers. “Tire performance needs to grow with the equipment.”

Tires with the AD2 technology have a footprint larger than the footprint from a same-sized standard radial. This improves traction to help reduce both field time and fuel consumption, while also reducing soil compaction, the company says.

“Our AD2 technology makes these improvements possible without compromising endurance or service life,” Rodgers says. “And, the tire’s greater sidewall flexibility also improves operator comfort.”

The tires will come in five sizes, two for front-axle applications on MFWD tractors and three drive tires for MFWD rear axles and 4WD machines. The sizes are IF420/85R34, IF600/70R30, IF480/80R50, IF710/70R38 and IF710/70R42. For more information, visit

The new line of Firestone farm tires features Advanced Deflection Design (AD2) technology, which allows greater sidewall flexibility. The tires meet the North American Tire and Rim Association’s Increased Flexion (IF) standard. Compared with standard Firestone radials, the new radials can carry heavier loads at the same pressure, or the same load at lower pressures.
