Continuous research and development efforts by tyre manufacturers show that tyres can be improved by adding a special supporting sidewall structure that allows the tyre to make it to the nearest service station completely devoid of an air pressure. This work evaluates the performance of a run-flat tyre that combines unique wheels and tyres used for original equipment vehicle applications. It involves the analysis of maximum tangential force at the instant of tyre burst, reaction at the supports and run- flat tyre vibration. It has been shown experimentally that the vibration of a run flat tyre in the region near the contact patch can be represented by a set of decaying waves thus; a run flat tyre was modeled as a lossy wave guide in which decaying waves propagate in the circumferential direction. The gliding times obtained before inserting run flat tyre for gliding distances of 200, 300, 400, 500, 600, 700, 800, 900, 1000, 1100 and 1200m are 150, 180, 205, 230, 255, 270, 295, 315, 335, 360 and 400s. Similarly, the gliding times obtained after inserting run flat tyre for the same distances mentioned above are as follows: 100, 120, 150, 170, 190, 225, 255, 275, 290, 320 and 340 respectively. It can be concluded that the vehicle maintained its linear driving at maximum left and right turns
