DALLAS - Three new Bridgestone commercial tires were introduced this week at the 2011 Great American Trucking Show (GATS) Aug. 25-27, 2011, in Dallas, Texas. They are the Greatec R125A, the M799 mixed service radial, and the M770 drive tire.

Bridgestone Commercial Solutions (BACS), a division of Bridgestone Americas Tire Operations LLC, says the Greatec R125A offers more payload, longer tire wear and a reduced cost per mile. It features an exclusive belt system to maintain casing shape, with a wide top belt that is optimized for better irregular wear resistance and a waved belt design that holds the tread flat against the road for long, even wear and strong handling.

The tire includes an equalizer rib structure and defense groove design. Both sidewalls have protector ribs to fight curbing, cuts and impacts. The R125A also features a mineral-additive inner liner to minimize air loss and combat oxidation of the steel cords. Other design elements include stone rejector platforms, cross-rib sipes to improve traction on wet roads, and stress-relief sipes that absorb rib edge stresses and increase mileage the tiremaker added. The Greatec R125A comes in size 445/50R22.5 (L).

The M799 mixed service radial is designed for fleets that need a long-wearing tire for on-highway service and occasional use on gravel roads and debris-filled job sites. Bridgestone says the tire's all-steel casing provides durability and retreadability, while casing-saving stone rejector platforms help prevent rocks from being trapped in the tread and drilling their way into the belts. Thick ribs on both sidewalls protect the casings from cuts and abrasions.

The M799's cap compound is engineered for on- and off-highway use, while the base compound helps shield the casing from damaging heat for enhanced retreadability. A top steel belt fights flats by adding protection against road hazards. The M799 is available in sizes 11R22.5, 11R24.5 and 12R22.5.

Bridgestone says the M770 open-shoulder drive axle radial is designed for high traction and high scrub applications in long haul, regional and pickup and delivery service. The M770 combines greater tread volume for longer mileage with good traction in all weather conditions. The tire features a groove and block shape to fight lug base cracking and tearing.

The M770 offers stone rejector platforms in all grooves to help prevent stones from getting trapped and drilling into the belts, increasing retreadability. The M770 is available in size 295/75R22.5 (G). Sizes 285/75R24.5 (G), 11R22.5 (G/H) and 11R24.5 (G) will be added in 2012.
