Abstract: Ride comfort of wheel loaders plays a vital role in ensuring operator safety, work efficiency, and long-term health. This study explores the impact of tire stiffness on ride comfort under varying operational loads using a half-machine dynamic model. The evaluation is based on the root mean square (RMS) values of vertical acceleration at the driver’s seat (aws) and pitch angles of cab (awc), following the ISO 2631:1997(E) standards. The simulation results demonstrate that tire stiffness value significantly affect ride comfort when the machine operates under an ISO class E road surface at a speed of 5 km/h and full load. The outcomes offer a theoretical foundation for optimizing wheel loader tire parameters to maintain acceptable ride comfort during real-world operations.
