Based on nonlinear finite element analysis software LS-DYNA，using shell element model to simulate cord-rubber composite materials，the finite element model of 215/60R16 radial tire was established，and the tire blow-out process was simulated by different inflation pressure. Under different inflation pressure，the tire deformation at vertical，transverse and longitudinal load was analyzed. The results showed that the stiffness of tire declined sharply with the decrease of inflation pressure，and the vertical，transverse and longitudinal stiffness were reduced to about 30%，38% and 40% of normal inflation pressure after tire blowout，respectively. The three-dimensional stiffness variation characteristics of tire under different inflation pressures obtained in this study could provide a basis for the dynamic response and handling stability analysis of tire blow-out vehicl ? 2019 Editorial Office of China Rubber Industry.
