Is it possible to simulate the skidding of rear wheel during braking?

It is possible that the rear wheel could skid due to the placement of the center of gravity (CG) causing a high transfer of weight to the front, or due to sudden braking.
Is it feasible to recreate these scenarios in a simulation in order to determine the optimal CG position?

    Of course it is possible once you correctly set the friction coeff. and slip ratio.

    Honestly I would focus on how much braking torque you can apply, rather than CG position

    In my opinion, the current model I'm working on has a CG offset of 70-80 cm which may be causing the rear tire to skid, especially when sufficient braking torque is applied.

    I'm unsure about how to set the friction coefficient and slip ratio. Is this information provided in the .tir file? I don't have access to the tire data specific to model I'm working and I'm hesitant to modify any parameters other than the dimensions in the .tir file. What is the best course of action for me to take?

    Best regards.
