Rolling resistance

Last reviewed: 2026-05-20

The energy a tire consumes as it flexes and recovers while rolling under load. Lower rolling resistance can reduce fuel consumption, but the result depends on tire design, tread depth, casing construction, inflation, axle load, speed, road surface, and alignment. A low-rolling-resistance tire still performs poorly if it is run underinflated or in the wrong application.

Correct inflation reduces unnecessary rolling resistance without creating overinflation problems. Compare fuel-oriented tires alongside tread life, traction, retread policy, and the fleet's real removal reasons. The lowest rolling-resistance option is not automatically the lowest cost per mile if it wears out too quickly in the route.

Real-World Use

A fleet evaluating fuel economy uses rolling-resistance ratings alongside pressure records, alignment history, route type, and actual tire removal mileage. The final choice is made from cost-per-mile data rather than a fuel claim alone.
