The details is that the wheels in LFS are generated on the fly (I think using a spline and a cross-segment) instead of modeled , and that it is that way because the tires are generated on the fly.
So what I'm asking for basically is for the wheels to be modeled. You really don't want the wheels to deform, never, so I believe they don't need to be generated on the fly. The tires do, but not the wheels. So basically, the wheels can be modeled, which would probably look better anyways. That way they could look better, have bolts, be textured....and I'm sure there are other benefits.
