To provide a tire noise prediction device capable of easily and highly accurately predicting tire noise.SOLUTION: A tire noise prediction device 10 for predicting noise caused by vibration of a tire, includes a tire model creation part 21 for creating a tire model M1 formed by modeling the tire, a surface-vibration acquisition part 22 for acquiring surface vibration of the tire model M1 under vibration, when a prescribed position P of the tire model M1 is vibrated by changing frequency, an acoustic space model creation part 24 for creating an acoustic space model M3 formed by modeling sound pressure distribution around the tire surface when the tire surface is vibrated, and a noise prediction part 25 for predicting tire noise by acquiring the sound pressure distribution when the tire surface of the acoustic space model M3 is vibrated by the surface vibration under the vibration.SELECTED DRAWING: Figure 4
