2011 bmw x5 diesel rim question

[eugeneberet]

Hi there, i am new to this forum, but a long time BMW X5 driver. Since 2001, i have had 3 X5`s and i just ordered a new one last week, delivery in 4-6 weeks. i got a 2011 xdrive35d in deep sea blue metallic with black nevada leather interior with navi, heated seats, ipod connect, smart phone connect, and bluetooth.
the rims on the care are very bland.
i was reading on this forum about the X6M rims, and how the center needs to bored... i do not really know what that means.
but either way..
what rims will fit on my car?
i wanted to save some $$ and not order them from BMW
