Open up a wheel from an existing car in your game in 3DSimEd and have a look at the
material for the wheel centre, you'll see the !Event data at the bottom of the materials
page. This is the data for the wheel animation. The reason for the blurred textures is that
the wheels don't actually rotate 1 to 1 in game. There is the stationary texture, a slow
speed blur, and a high speed blur. To do your textures open them in your graphics program
and use radial blur on them, one to a degree of 15 and one to a degree of 30, also
check the alpha layer blurs if you are using wheels with transparencies.

Apart from TICTOC's hints I'd suggest to eliminate all static shadows, reflections and highlights, if you are using a photo like the ones above. The game creates it's own lighting-effects and it looks odd, when a static shadow rotates around the wheel.

Rather: you keep non directional shadows and highlights. An ambient occlusion map is good for rims as long as the source of light is perpendicular to the rim plane. The left picture is more or less ok in that respect, but not the one on the right.
