CHICAGO (April 15, 2004) —Bridgestone/Firestone (BFS) debuted three Bridgestone-brand radial truck tires during its Bizcon 8 commercial dealer meeting in Chicago this week.
The R287 steer radial is built to deliver long tire life for long-distance fleets, BFS said. It features side groove technology to help prevent edge wear and shoulder tearing, and equalizer rib technology to help fight the initiation and spread of edge wear on main ribs. The tire has a shallow 16/32 ½-inch tread and stiff compound.
The new M726 EL — for “extended life” — drive radial offers a deep 32/32 ½-inch tread with a tough compound that produces stiff blocks for resistance to heel-and-toe wear while increasing wear, stability and offering better heat resistance. The company said the M726 EL casing takes a full-size drive recap and incorporates four full steel belts with an all-steel casing ply. The tire is designed to minimize heat buildup for long life and retreadability.
The R195F trailer radial combines irregular wear-fighting designs for longer original tread life, offering long distance line haulers lower cost per mile, BFS said. The tire incorporates the Nashville, Tenn.-based tire maker's defense groove and equalizer rib technologies to combat initiation and spread of wavy wear on the main ribs while offering stress relief siping along rib edges to fight river wear.
To enhance retreadability, the R195F features thick sidewall protector ribs to fight damage and abrasion from curbing. BFS said both sidewalls are ribbed so that when one set of protector ribs is worn away, the tire can be reversed on its wheel for continued protection. The company said the new tire's casing — featuring four full steel belts and an all-steel casing ply — is engineered to be retreaded for any axle position.
