They are all from my mods I am slowly preparing. While those wheels are ready, I need still work on suspension for them (they use DLC suspension as placeholder), and also other rover related content. I had already prepared 3x3 and 5x5 wheels, and plane wheels. I need prepare also prepare small wheels in style of mars rover, and retractable suspension for planes (animation engine + custom script that will lift wheels) when I got ready script. Then I will release them. Cocpit also will be releasen as soon as I prepare few others I am planning

Jeez, where did those wheels come from? They're glorious!!
