BMW 320 removing the wheel... it's a 5 spoked alloy.. I've removed the 5 main bolts but can't get the wheel off !!! There are 5 smaller holes all around the wheel... maybe there are smaller bolts in there ? what are the 5 small holes for ?
... there's a picture of the type of wheel I'm talking about (with the 5 smaller holes...) ... at the following link :

The gap between the hub bore on the wheel and the pilot on the rotor is about a tenth of a millimeter. As other people have mentioned, over time, corrosion will build up and make the wheel difficult to remove, especially if you live where it rains or snows allot.
The other smaller five holes are for wheel alignment at the factory. This is a German alignment tool. Here in the states alignment is done by clamping a fixture on the rim flange. This is why until recently getting 24" or 26" wheels aligned was a problem. The fixtures weren't made big enough to clamp on the rim flanges.

Your alloy wheel is seized to the rotor/drum. Happens quite often with BMW's. I suggest going to a garage for to remove the rim you will have to raise and safely support the vehicle. Once the vehicle is safely supported take a good block of wood. I recommend a 2x4 cut 6" in length. Place the block of wood against the inside of the rim at the lowest point the hit the block of wood with the hammer. After a couple healthy hits the rim should pop off. I see it all the time. It has to do with the difference in the metals and the way the heat and cool off when you drive the car.

The center of the brake rotor fits very snugly into the same size lip/hole in the center of the wheel. Over time it will corrode, making the wheel stick to the rotor. A few good kicks or rap with a hammer should break it free. I have an M3 and swap wheels/tires between summer/winter. Happens all the time.

If hammering fails, let the car gently down off the jack with the bolts removed, and try again. If that isn't enough, let it down and rock the car back and forth or move it 5 feet or so. Then raise the car on the jack again and the wheel will pop right off.
If you can't lower it (you're on jackstands), then try hitting the inside wall of the tire with a 2x4. Don't hit the rims.

You are going to have to beat it off,alloy wheels are known for this...what it does is oxidizes (aluminums version of rust)...and when you put it back on,use some anti seize.There will be like a white powdery stuff,take some sandpaper and sand that stuff off.
