but can't get it off !!! 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 :

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.
