From page 1...
... This testing identified the OBSI probe location in the vertical direction, vehicle speed, and vehicle loading to be the factors contributing to the variation for the ranges and parameters evaluated. Within reasonable limits, probe distance from the tire, probe fore/aft location, and tire inflation pressure were found not to be critical.
