Currently, the way you describe an aircraft's landing gear is very simplistic. Each gear is just described as one contact point. Even if the gear consists of, to take a typical airliner main gear as an example, a bogie with two axles, with two wheels on each axle. The bogie is able to rotate a bit around its axle, which is attached to the oleo strut. The simulator has no idea about this, to it the gear is just described as if it was a single wheel with no other degrees of freedom than that which the vertical compression of the oleo strut gives.
