In a braking performance evaluation method including the steps of acquiring a tire ground contact pressure distribution, acquiring a sliding friction coefficient table, and calculating a friction force of an entire tire using a brush model having a function representing the tire ground contact pressure distribution and the sliding friction coefficient table, the step of acquiring the tire ground contact pressure distribution includes the step of acquiring a first ground contact pressure distribution on a road surface on which no water film is present via actual measurement or calculation and the step of acquiring a second ground contact pressure distribution by applying reduction in a ground contact pressure due to a water film intruded between the tire and the road surface to the first ground contact pressure distribution and using the second ground contact pressure distribution as the tire ground contact pressure distribution used for the calculating.
