Recent field studies have established that operational truck tire inflation pressures are much higher than those typically assumed in the pavement design process. Field data have shown that tire inflation pressures for trucks operating on the highway average between 95 and 100 pounds per square inch (psi) while 75 to 80 psi is usually assumed in pavement design. The report presents the results of a study into the feasibility of automatically monitoring the contact tire pressures produced by trucks while they are in motion by monitoring tire footprint dimensions and weight. The work undertaken has included: a review of principles of tire contact pressure measurement and available sensor technology; an assessment of the feasibility for using each principal/technology; for truck contact pressure measurement; development of the concept for an independent tire contact pressure measurement system as well as options for operational truck weighing-in-motion (WIM) systems.
