Chaos Vehicle for Steam Locomotive not working properly

I’m trying to rig a locomotive and get it to move using chaos vehicles. However, I’m running into a lot of issues. The wheels of my mesh keep clipping through the ground, which is preventing the vehicle from moving. In addition, my wheels won’t spin. Is there a fix for this? I’ll also include a video to show you what I mean. Any help would be very much appreciated.
