PROBLEM TO BE SOLVED: To provide a method capable of accurately predicting temperature distribution of a tire during traveling. SOLUTION: In this method is performed, a stress analysis model is developed composed of a tire model, a rim model, and a road model. Stress analysis is made by respectively giving physical properties such as density and an elasticity modulus to the element of each model. The heat generation distribution of the tire is determined by calculating stressσand the amount of strainεacting on each part of the tire. In executing heat analysis calculation based on the heat generation distribution, a three-dimensional heat analysis model constituted by adding a numeral analysis model composed of the tire model 40 and the rim model 50 to an inside air model 60 which divides air inside the tire into finite elements, a cut sample model, or an axisymmetric heat analysis model M2 to obtain the temperature distribution on the surface of and inside the tire by executing heat analysis calculation on the heat analysis model M2.
