Kahlog,
The Robart wheels have Goodyear on one side and Continental on the other. While you are probably correct about the tread design, you can also get them in regular tread as well. Either way what does it matter when the wheels are sucked up into the wheel well? I don't plan on entering any contests with this bird but the Me109 is a favorite of mine and I will just do a few extra touches of my own liking while staying within the normal scheme. One things for sure, the paint and markings will have to change. I was thinking of doing this scheme. Plane was used to ferry ranking US POW in the Italian theater during WWII. It's definitely different!

Happy Flying!
