Who Knew Tires Could Improve Fuel Efficiency?
Single wide-base tires, which replace two traditional width tires, on a new combination tractor and trailer could reap annual fuel savings of about 2%. Single wide-base tires save fuel by reducing vehicle weight, rolling resistance and aerodynamic drag. A 2% reduction in fuel consumption translates into a carbon dioxide reduction of more than 3 metric tonnes. Driver Training & Technology Are Formidable Collaborators Even highly experienced drivers can boost their skills with training aimed at raising fuel economy. Fleets that have done this report fuel savings of between 5% or 7 metric tonnes of carbon dioxide per year and 20%. Driver training programs consist of such things as learning about progressive shifting, engine speed optimisation, idle reduction, smoother braking and acceleration, anticipatory driving, speed control and optimal gearing. For example, an idling truck can burn 3 to 4 litres of diesel fuel per hour. Reducing unnecessary idling could cut up to 19 tonnes of carbon
