Power Loss of Truck Tires Under Equilibrium and Transient Conditions 762030

A test program to measure the rolling resistance characteristics of selected 11 x 22.5 truck tires was conducted at the Calspan Tire Research Facility (TIRF). Test data from this study provide a data base which contributes to the understanding of truck tire rolling resistance and its relationship to operating variables. The influences of tire wear, speed, load, torque, slip angle, inflation pressure, temperature, construction, tread pattern and distance traveled on rolling resistance were investigated. A short description of the test program and a brief summary of the results are included in this paper.
