This is my representation of Unimog U423 built in scale 1:15
For this purpose, I use 68.8x24S tires which are very rare,
but real Unimog has allways a bit biger wheels than ordinary 
truck. Since I live in a country where we tend to use smaller
equipment depending on natural diversity characteristical for
our coutry, I've decided to use scale 1:15...
