I am simulating full vehicle (tractor with trolley) at constant velocity. I am unable to see the impact of change in rolling resistance on the vertical tire force or in general stability of vehicle. I am adjusting rolling resistance by changing "rolling resistance torque coefficient" in property file (PAC2002).
@Martin Kieltsch You are right. That measure gives rolling resistance moment about tire centre. I got confused because its name is just "rolling resistance" which doesn't specify force or moment. Thank you @JSlat & @Martin Kieltsch!!
