Abstract:A triaxial load pin array for measuring tire footprint pressures was recently purchased by TTI. This report describes our initial experience and results obtained with the array during a 3-month summer period in 1992. Footprint pressure distributions were measured for two highway-type radial truck tires (a conventional single and a wide base single) and a smooth tread truck tire. The data obtained compare well with footprint pressures measured at the University of Texas, Cooper Tire Co., and Goodyear Tire Co. Data showing the effects of tire inflation pressure and tire load on footprint pressure are included in the report.
