To me, those pictures look like water is sitting somewhere, turning orange from oxidation of metal and spraying out when you drive, leaving the oxidation behind. In fact, in the photos I can even see where it's coming from. Look at "brake dust 2" and focus on the small drainage holes next to the lugs. You can see that they are rusty on the inside and you can see that the rust continues from the hole radially outward towards the lip down the face of the wheel.
