Log transport research – Evaluating aerodynamic drag and rolling resistance.
FPInnovations carried out long-term studies on the above on Canadian Class 8 tractor-trailer combinations. Vehicles equipped with low-rolling resistance tyres, speed limiters and trailer skirts (where applicable for use), showed a 5.25% improvement in fuel consumption for Less-than-Truckload (LTL) freight, and 5.11% for two 8-axle B-train tractor0trailer combinations with single wide-base tyres.
