The aim of the present work was to create a radial tyre capable of working at atmospheric pressure in the tyre cavity, with retention of the profile and dimensions of a pneumatic tyre with practically the same mass. This was achieved by replacing strands of the carcass with elastic elements taking up the radial load on the tyre. The elastic elements of the carcass have the profile shape of the inflated tyre, given to them on a special template. The breaker was manufactured from the same material as the elastic elements of the carcass and was arranged in the circumferential direction. A reinforcement method was developed and certified on model specimens. At present, different models and methods are used to calculate tyres. These methods make it possible, with sufficient accuracy for practice, to predict the deflection of the tyre, the parameters of contact with the bearing surface, the stress-strain state of the elements, and the temperature in the tyre. Comparison of these methods showed that more accurate analysis of the main characteristics of tyres is possible by means of a model of a non-linear elastic body with the use of the finite element method (FEM). On the basis of the conducted comparative analysis of experimental and calculated data it can be concluded that the developed model and procedure for calculating safety tyres with elastic elements in the carcass have high goodness of fit. The given procedure can be recommended for optimisation of the design of safety tyres at the planning stage.
