Abstract

The main aim of the research leading to this paper is to select---for a truck and its transport application---a configuration of the tyres such that the energy losses caused by these are minimized. We show that neither the rolling resistance coefficient (RRC) classes provided by tyre suppliers nor any other nominal values of RRC evaluated for specific operating conditions are sufficient to do the tyres selection. Therefore, a surrogate model of the RRC is developed. A tyre model based on the RRC model is introduced in this paper. The modularity of the tyre model is demonstrated by coupling it with two different vehicle models and an~operating environment model. The usage of the joint vehicle, tyres, and operating environment model is demonstrated by solving a few illustrative instances of the tyres selection problem. The potential savings wrt. energy losses when the selected tyre configurations are used are presented.
