Tire performance prediction device, performance prediction method, and trained model generation method

Abstract

A tire performance prediction device is provided that can estimate distribution data of physical quantities acting on the tread portion of a modified tire obtained by modifying the tread pattern of a reference tire. [Solution] A tire performance prediction device includes a trained model storage unit that stores a trained model (26B) that has been machine-learned to extract feature values ​​from distribution data (22) of physical quantities acting on the tread portion of a reference tire (11) when the tread portion comes into contact with a road surface and a pattern image (23) of a modified tire (12) whose tread pattern is modified from the reference tire (11), and that can output distribution data (24) of physical quantities acting on the tread portion of the modified tire (12) when the tread portion comes into contact with a road surface.
