Tire Footprint Measurements of Commercial Truck Tires

Abstract

This data publication presents high-resolution measurements of tire contact patch pressure distributions obtained using a capacitive pressure-mapping sensor with 1.6 mm spatial resolution and 65,536 sensing points. The dataset captures contact pressures between 69 kPa and 2070 kPa for two commercial truck tires. Footprints were recorded at various wheel loads under a constant inflation pressures, providing detailed insight into load-dependent pressure behavior. All measurements were taken with the sensor mounted on a flat surface within the experimental setup, while the ika’s tire stiffness test rig (SteiReP) supplied controlled loading conditions to ensure repeatable data acquisition.
