A tire physical information estimation system (100) includes a physical information estimation unit (32) and a data acquisition unit (31). The physical information estimation unit (32) that includes a learning type arithmetic operation model (32a) including an input layer (50) through an output layer (54) and estimates tire physical information produced in association with movement of a tire (10). The data acquisition unit (31) acquires input data input to the input layer (50). The arithmetic operation model (32a) includes a feature extraction unit (51) that performs a convolution operation (51a, 51c) in an operation halfway between the input layer (50) and the output layer (54), the arithmetic operation model (32a) outputting normalized tire physical information in at least two axial directions from the output layer (54).
