According to the North American Council for Freight Efficiency, low-rolling-resistance tires are proven to save fleets fuel. Low rolling resistance tires are meant to minimize wasted energy as a tire rolls, decreasing effort expended by the vehicle and improving fuel efficiency. Approximately 5-15% of the fuel consumed by a typical vehicle may be used to overcome rolling resistance according to the US Department of Energy.
The NACFE is a huge proponent for fleets adopting these tires for their vehicles, stating that the fuel savings will largely offset the higher price tag and shorter tire life. NACFE's Low Rolling Resistance Confidence Report delves into the benefits and challenges of switching to more fuel-efficient tires, and doesn't shy away from the traditional fleet concerns about the tires, such as shorter overall tire life, traction and driver acceptance. The conclusions of the report draw heavily on the experience of large and small fleets that have significant experience with low-rolling-resistance tires. Some of the feedback came from face-to-face interviews with fleet managers, maintenance managers and tire experts, many of whom shared their own documented experiences with the tires.
The group also compiled insights from 53 medium and smaller fleets, 36 of which had direct experience with low-rolling-resistance tires, via an online Fleet Forum and several tire-use surveys.
The conclusions drawn from the participating fleets were not universally in favor of the tires, but results spoke strongly to benefits felt by a majority of the fleets that had experience with them.
Adopting these tires may be beneficial for some fleets and drivers, but not all. We recommend researching the tires and weighing the costs and benefits before committing an entire fleet to them.
