Rolling resistance
The force required to keep a tire rolling at constant speed. Lower rolling resistance reduces fuel consumption. Tire design, inflation, load, temperature, and speed all affect rolling resistance.
Correct inflation reduces unnecessary rolling resistance without creating overinflation problems. Low rolling resistance tire designs contribute to fuel economy when combined with proper maintenance.
Real-World Use
A fleet evaluating fuel economy uses rolling resistance ratings alongside correct inflation and alignment as inputs in their tire cost-per-mile analysis.
