Application Summary AI generated
This standard specifies the test methods for measuring the rolling circumference of passenger car tyres under specified load and inflation pressure conditions. It is applied in tyre manufacturing and quality testing to determine the tyre's effective rolling radius, which is critical for vehicle speedometer calibration, odometer accuracy, and anti-lock braking system (ABS) performance. The standard is used by tyre producers, automotive OEMs, and testing laboratories to ensure consistent tyre dimensions for passenger vehicles.
