I can't think of a suitable property that you could link to that would give a slowdown. You could use the inverse of agl but then the wheels would start spinning before you touched down (can anyone tell me if a good solution for pre-spinning the wheels on airliners before touch down has been found yet? The airline companies were very keen to find a solution to this as those skid marks on the runway are very costly to make). Perhaps the best way might be to include the wheel diameters in the fdm configs, which are then processed by a bit of new code to put the wheel rotations in the property tree. You might be able to do the random bit by using the pitch, roll and yaw values from the tree to control the rotation. With all three factors influencing the animation, at different rates, it should look pretty random. I think there may be some problems with the way that the u/c gear is handled in FG - not in terms of the way the code works but in the way that the gear structures are represented in different branches of the property tree and it might be better to resolve those before adding more wheel features.
