Self-supporting run-flat tires (SSRFTs) achieve good zero-pressure driving ability by reinforcing the sidewalls, and the structural shape of sidewall insert rubber (SIR) is critical in influencing the mechanical characteristics of SSRFTs. In this paper, an SSRFT contour model is established by combining the radial tire contour theory and the design elements of SIR. The influence of two design parameters (maximum width L and maximum thickness H) of SIR on the tire stiffness characteristics and the contact characteristics is analyzed in depth, and the accuracy of the model is verified by the tire mechanics bench test. The results show that the radial stiffness of SSRFTs is positively correlated with two design parameters; an increase in L affects the stress concentration at the end of SIR, while a change in H has a more drastic effect on the stress distribution of SIR, leading to a large change in both the location of the deformation of SIR and the maximum equivalent stress; under rated pressure conditions, when L is less than 100 mm, the overlap between SIR and the tread decreases, which in turn makes the contact characteristics of SSRFTs closer to that of a normal tire, and obtains better comfort and abrasion resistance; under zero-pressure conditions, the maximum contact stress of the tread is the smallest when the H is 8 mm, but when H is less than 6 mm, the contact characteristics appear to deteriorate uniformly, and the maximum contact stress continues to rise. The results of the research provide a reference value for the selection of the design parameters for SIR and the optimization of the dynamic performance of SSRFTs.

“…In order to solve the safety problem of tire blowout, major car manufacturers have developed tire blowout monitoring and braking control systems [3], tire pressure monitoring system [4], intelligent tire system [5], as well as active safety control system [6]. For this reason, run-flat tires with technologies such as sidewall enhancement [7], honeycomb structures [8][9][10], bionic structures [11][12]and new spoke structures [13][14] have emerged from the perspective of improving the autonomous characteristics for vehicle blowouts, but the characteristics of run-flat tires differs significantly from that of NT, so the tire blowout characteristics of vehicles equipped with run-flat tires need to be further explored.…”

Run-flat tires are an important solution to solve the traffic accidents of tire blowout and the inserts supporting run-flat tire (ISRFT) can effectively solve the problem of zero-pressure driving after the tire blowout. Since the characteristics of vehicles equipped with this run-flat tire after tire blowout is different from that of normal tires, a reasonable tire model is required to develop the dynamic response characteristics. In this paper, the theoretical analysis of the zero-pressure rolling for the inserts supporting run-flat tire was firstly carried out, and steady-state mechanical characteristics tests were conducted to obtain the mechanical characteristics. Secondly, a dynamics model based on the UniTire model was developed for inserts supporting run-flat with the consideration of camber angle.Finally, three sets of typical working conditions were selected to compare the effect of different camber angles on the tire blowout parameters of vehicles equipped with inserts supporting run-flat tire and normal tire (NT), which proved the superiority characteristics of inserts supporting run-flat tire. This study provides a basis for improving the autonomous characteristics of vehicles.
