This procedure specifies the testing method for determining the Tyre Stiffness Index of passenger car tyres for the products capable to supply the vehicle with the basic tyre functions, at least, at a speed of 80 km/h (50 mph) and a distance of 80 km when operating in flat tyre running mode, as per ISO 16992. Such method is meant to determine the above mentioned Index, for the characterization of the expected tyre’s stiffness through its Air and Structural components. To reach the target, the vertical force and the vertical deflection - in the sense of absolute position in Z direction - under different operating conditions are measured (approximated in case of zero inflation pressure) and combined through the metrics hereafter defined.
