To keep a tractor-trailer moving at highway speeds, the trucks engine has to consume fuel to produce the horsepower required to overcome drag forces. Overcoming tire rolling resistance is not the only drag force consuming fuel. Rolling resistance is responsible for about one third of a tractor-trailer's drag forces, making it an important contributor to fuel consumption. (The largest source of drag force on a truck is aerodynamic drag. Frictional drag in the truck's drive train plays a smaller role in determining a rig's fuel consumption.)

In general, a 3% reduction in the total rolling resistance of all 18 tires on a standard tractor-trailer will provide about 1% improvement in controlled SAE Type II truck fuel economy. Breaking it down further, to achieve the same SAE Type II fuel economy savings, the truck's steer tires would require a 20% reduction in rolling resistance, while the drive and the trial position tires would only require an 8% and 6% reduction, respectively.

How does rolling resistance translate into miles-per-gallon and dollars-and-cents savings for your fleet? Enter your specific information into the below calculator to find out!
