Some of the engineering sims I use at work (space shuttle) have very detailed models of landing gear and tire spinup, etc. Of course, we don't ever see power trains driving the wheels (at least we don't in JSBSim). There are some simplifications made in our gear model that suffice for modeling what planes do. However, out of curiosity, I am interested to see how ground reactions are modeled for autos - particularly for the case when the vehicle is at rest. I am familiar with Pacejka's magic formula, etc. It can be a complicated problem, so it's useful and interesting to see how others approach the problem.
