In order to improve the explosion prevention and bullet-proof ability of wheel vehicle tires in the serious environment, a spring tire was put forward based on the performance of high strength and deformation recover of metal coil spring. Structure parameters of each tire part were analyzed and three-dimension model for spring tire was established. The performance of strength and stiffness of spring tire were analyzed with finite elements software and simple wheel vehicle experiment was operated. Combining the analysis, it is validated that the structure efficiently improves safety protection ability and theoretical model and simulation model of spring tire are right. With getting performance criterion of spring tire strength and stiffness, deformation phenomenon of experiment provides theoretical guidance for analysis and optimization of spring tire performance
