Wheel / Tyres are first base coated dark greys
Every area of operation leaves the tyres looking different. Pictures of Iraq showed the tyres had very light raised treads with dark groves in between, this was depicted by dry brushing each tyre.
Tyres were masked and the wheels painted to match the body colour. This colour was lightened and sprayed onto the rim from an angle above to add some highlight.
Oil washes of black and dark brown help to bring out the detail further. Pigments then used to "dust up" the tyre sidewalls.
Fitted to the Humvee, more dust will be added once the scene is fully assembled.
