A study was undertaken to investigate the effects of road surface properties on the rolling resistance (and hence fuel consumption) of medium-sized trucks and passenger buses. The coast-down technique was used and proved to be practical and repeatable. The results indicate that road roughness and tire pressure are both significant in determining rolling resistance. Road surface properties can be expected to affect fuel consumption by as much as 20%. Typical tire pressure increases could cause as much as 6% less fuel to be consumed on the same surfacing.
