I have no idea what's going on with that wireframe. Is the side of the tire a flat plane with a transparent center, and the rim is floating unattached?
It does translate into games. Whether or not it's very noticeable is another matter. On DS stuff, there's a good chance an incorrect tesselation will show up. Think of the quad as a piece of paper. You place it flat on a desk, it's flat. You hold two diagonally opposite corners in place, and pull the other two corners…
