With an increased interest in a non-pneumatic tire (NPT) and its possible performance on safety in driving and low rolling resistance, extensive research on mechanical properties including dynamic characteristics are required to explore for the commercialization of NPTs. In this study, we explore the dynamic characteristics of NPTs with flexible hexagonal lattice spokes. A steady state vibration characteristic of NPTs is investigated with a series of load carrying capability and rolling speed for two hexagonal spokes using a commercial finite element code, ABAQUS. The obtained vibration characteristics are compared with those of conventional pneumatic tires, which are available in the literature.
