ANALYSIS OF ROLLING RESISTANCE OF TIRES WITH RUN FLAT INSERT APPLYING DRUM METHOD AND RADIAL CHARACTERISTIC

Abstrakt

This paper presents analysis of rolling resistance of tires with RUN FLAT insert applying drum method and radial characteristic. The conducted studies indicated changes in operational properties of wheel, occurring as a result of inflation pressure drop in the wheel. As regards radial elasticity, such changes result in significant drop of radial rigidity and increase of static deflection and increase of tire rolling resistance. The application of Run-Flat insert in wheels allows for driving with depressurized tire, but road tests disclosed that several restrictions to the driving with flat tire must apply. The wheel with Run-Flat insert allows in case of depressurization for good force transfer in radial direction from the wheel to the pavement but with significantly increased radial rigidity and considerable tire deflection. Driving without inflation pressure leads to high increase of rolling resistance thus also to very high increase of tire temperature. The wheels with Run-Flat inserts provide safe vehicle driving after tire depressurization, but only for very limited distance and time. It is also difficult for driver to control the tire condition and assess distance that may be driven without total tire destruction.
