Oh, that looks a lot like how MaksArt does it with his ZIL 4906 truck which I finished building a couple of weeks back. The Komatsu version here has a nice subtlety in the rounding of the tread surface, though, which I really like. The rounding makes the wheel look much more realistic. Interesting to see this.
What I liked in the wheels of MaksArt's model is that the sidewalls of the wheel are made in one part, not two like in this build. You just need to curve the paper to get it bulged like the wheel's sidewalls are. (

Now I would like to see a paper wheel (stationary of course) where the bottom half is a little more flattened (and the sides bulged out a bit more) by the weight of the vehicle. Interesting problem to get one's head around. How would a shape like that fold out?
