Bridgestone Greatec wide base radials are now available through authorized Bridgestone dealers, truckstops and original equipment manufacturers. Greatec radials are designed to directly replace tractor dual assemblies without need to modify axles. In addition to directly converting vehicle weight into revenue-paying load, Greatec radials could also provide fuel economy advantages, saving approximately 2 to 5 percent on vehicle fuel consumption by comparison to conventional, non-fuel-efficient dual tire assemblies.
