THE INFLUENCE OF TIRE GEOMETRY ON THE ROLLING EFFICIENCY OF COMMERCIAL VEHICLE TIRES

A parametric study is conducted of the efficiency with which a pneumatic tire carries a load. The tire is described in terms of its diameter, section width, inflation pressure, and deflection. Both tire load and tire rolling resistance are also expressed in these terms. The ratio of load to rolling resistance is taken as a measure of tire efficiency, and is studied over a wide variety of possible truck tire geometries. Results show only moderate improvements in efficiency for most design possiblities, but when increases in tire lad are accompanied by increasing tire inflation pressures, large improvements in rolling efficiency are indicated. These imply substantial reductions in fuel consumption.
