ABSTRACT:
It is possible to significantly reduce a prediction error of the high-speed RFV and the high-speed TFV in a tire having a large PRO growth amount at high speed. Three or more sample tires are extracted from each lot. The PRO and RFV are measured and the least-square method is used to predict (100) the upper and lower and front and back natural angle frequency, attenuation ratio, upper and lower spring constant, and rolling radius coefficient. By using the PRO measurement apparatus, the PRO during idling is measured. By using an AAV measurement apparatus, an actual measurement value AAVLof the angle acceleration fluctuation at a low speed is measured (102). The PRO and AAV at a high speed are predicted (104) and the actual measurement value and prediction value are used to predict the high-speed RFV and TFV.
