Abstract：The basic concept of tire safety technology was briefly introduced, and the basic connotation, the structure and main categories of non-pneumatic wheels were described in detail. Several kinds of representative products of non-pneumatic wheels were enumerated with Tweel wheel, honeycomb wheel and mechanical elastic wheel, and the current technical status of non-pneumatic wheels was analyzed. Based on the vertical mechanical properties, the longitudinal mechanical properties, the lateral mechanical characteristics and the grounding and mechanics characteristic factors, the research status at home and abroad of mechanical properties of non-pneumatic wheels was reviewed, and the main advantages and disadvantages of non-pneumatic wheels were analyzed. The technical problems of non-pneumatic wheels in current research were pointed out, and the future development trend was predicted.
