Abstract
A comparison of tag-tandem versus drive-tandem operating considerations is provided. These considerations include fuel economy, traction, and other operating characteristics. Fuel economy testing using the SAE Type II procedure indicates there is statistically little or no difference between drive-tandem and tag-tandem fuel economy. A traction analysis comparing the gradeability of the two axles demonstrates the superiority of the drive-tandem axle. Recommendations for the truck operator are given.
