Multi-body vehicle dynamic simulations play a significant role in the design and development process of off-road vehicles. Thesesimulations require tyre models to describe the forces and moments, which are generated in the tyre-road contact patch. All externalforces acting on the vehicle are either generated in the tyre–road interface or are due to aerodynamic effects, which can be neglectedat typical off-road driving speeds. The accuracy of the tyre model describing the forces in the tyre–road interface is thus of exceptionalimportance. The parameterization of most tyre models relies on some experimental test data that is used to extract the necessaryinformation to fit model parameters. Acquiring the test data, with sufficient accuracy, is often the biggest challenge in the parameterizationprocess. Published data for large off-road tyres is virtually non-existent. This paper describes different methods to acquire therequired parameterization data. Experimental measurements are conducted on a 16.00R20 Michelin XZL tyre. Laboratory tests, as wellas field tests, over discrete obstacles and uneven hard surfaces were conducted. The paper presents an extensive set of parameterizationand validation test data on a large off-road tyre that can be used by researchers to develop and validate tyre models.
