PROBLEM TO BE SOLVED: To provide a tire simulation method advantageous to accurate analysis of tire performance. SOLUTION: The tire simulation method sets a finite element model by dividing the tire 10 into parts of the tire 10 except combined materials (bead part 12, sidewall 14, tread part 16), and parts of the combined materials (carcass 18 and belt 20). As shown in Fig.6(C), a combined material element model 70 of the carcass 18 (first and second belts 22, 24) comprises: a rubber part element model 70A in which the rubber part 18A(22A, 24A) is modeled by solid elements; and a cord element model 70B in which the cord 18B (22B, 24B) is modeled by the solid elements.
