You've got a bright sky and headlights on so the camera has metered fairly dark anyway so as not to over-expose those areas.

Ideally you need to manually over-expose to bring up the wheels. You'll blow the highlights (ie. the sky will be one big area of white instead of tones of grey etc.) but the pic will be lighter.

Failing that recompose so the rest of the pic is sympathetic to your subject - ie. its all dark and not so contrasty.

it means that because of the sky and the head lights the camera has choosen a fast shutter speed to balance the light. this means the sky etc is not just a blown white colour this means that the dark area's are even darker. put an object on the windowsill and take it's pic. the window will be ok but the object will be dark.

Forget about aperture, for the purpose of this explanation its not important.

Cam chooses shutter speed based on how much light is there, to expose the pic correctly, ie. not too light, not too dark. Shutter stays open longer = pic will be lighter. Shutter is quick = pic will be darker. The aim is to get a balanced pic that looks right and doesn't exhaust the dynamic range of the camera (ie. all the tones and colours).

The choice is usually based upon the mid-point of all light in the pic, ie. bits of dark, bits of light, but not one predominantly dark or light bit, the camera will be fine and go for the middle.

As your pic has loads of light stuff in it (big white sky, headlights, reg plate), its chosen to knock the average down a bit so the white gets exposed properly. Because of this the dark bits are very dark. Hence you can't see your wheels.

My suggestion earlier was to over-ride the cameras choice and manually over-expose the pic. Basically ignore the cameras opinion of what will look right and up the average yourself. The sky will go very bright indeed but no worry, thats not as important as seeing your wheels.

As a side note, brighter pics means slower shutter, which normally means shake unless you support the camera ideally on a wall or something, or most ideally on a tripod.
