Tires rotation

[bmw2099]

Im taking the summer rims off my car and putting my snows on for the winter. I just don't know which wheel to put on which 'hub', for a lack of better words,(which wheel goes where on the car)... or which one it was last on. There's writing on the sidewall behind the tires, but i dont even know what the hell they say. Any help would be greatly eppriciated. Hope this isnt too confusing.
Thanks
Joe

I know this is a little late, and you probably just got on with it by now, but unless on the sidewall of the tire itself (the outside, the part you can see) says that it has a certain direction rotation, you can put the wheel anywhere you damn well please. But if it has a directional rotation, make sure you put it on the way it says. In other words, make sure the arrows point towards the direction they'll be spinning.
