METHOD FOR ESTIMATING UNEVEN WEAR OF TIRE, AND DEVICE FOR ESTIMATING UNEVEN WEAR OF TIRE

A method and an apparatus for estimating uneven wear in the tire shoulder with high accuracy using a fewer number of sensors are provided. An uneven tire wear estimating apparatus includes an acceleration sensor (11) disposed on an inner surface of a tire tread for measuring radial acceleration, an acceleration waveform extracting means (12) for extracting an acceleration waveform in a post-trailing-end domain from output signals of the acceleration sensor, means for calculating a vibration level ± of an uneven wear measured band and a vibration level ² of a reference band from the extracted acceleration waveform, an uneven wear determination index calculating means (16) for calculating an uneven wear determination index ³, which is an index for determining au uneven wear, from the vibration level ± and the vibration level ², and a determining means (18) for determining whether an uneven wear is occurring in an edge of the tire shoulder from the value of the uneven wear determination index ³.
