Hmm, I'm not sure what the best method for adding tyre tracks is to be honest. I've seen a few related threads in the Blitz3D Programming forums, if you can find them they should give you some good ideas.
You can get the geom positions of the wheels with dGeomGetPositionX(geom), dGeomGetPositionY(geom) and dGeomGetPositionZ(geom), using this info you can then work out the position of the skidmarks. You can also get the orientation of the wheels using dGeomGetPitch(geom), dGeomGetYaw(geom) and dGeomGetRoll(geom), then using this info you can align the skidmarks with the wheels. I'm not sure which way would be best to align the skidmarks with the road surface though.
Yep, PaceMaker uses JV-ODE, it's an amazing animation tool. There's a demo you can try here...
