Abstract

The handling and lateral stability properties of the car are dependent on the construction and technical condition of the tyres. The price dependence of these parameters has often been not clearly defined. The comparison road tests offer a possibility to investigate these parameters of different tyres. The objectives of the current investigation were to determine the extent of difference and the price dependence of the passenger car tyres sold in Estonia. The handling properties of the test vehicle were evaluated taking into account the discrepancy between the maximum and the time-averaged lateral acceleration values obtained during the skidpad tests. The traction properties of the remould tyres and new winter tyres were experimentally found to be comparable in several road and test conditions.uThe results of the research show that the use of the summer tyre carcasses in remould winter tyre production potentially limits the lateral traction of the remould winter tyre. This can be related to a higher cornering stiffness provided by the summer tyre carcass. For experimental determination of the traction and the handling properties a GPS-based analysis system was used. For the covering abstract see ITRD E137489.
