Impact of change in rolling resistance.

Vivek7a
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).
Can anyone tell me more about it?

    The rolling resistance force will be Fxrr = Fz*LMY*QSY1 if all other QSYn are set to zero.
    And as LMY is by default set to 1 in a pac2002 file, it becomes the old equation Fxrr = Fz*QSY1
    So if you want a rolling resistance force =208600 N with a vertical load = 83000 N, you should enter QSY1 = 208600/83000 = 2.51
    There is a full description of this in the documentation.
     
    I just wonder what tire has a rolling resistance that is 2.5 times higher than the normal load?
