Let me start off by saying I found a place, finally. But I have called 10 different places to get my new heidenau's mounted and every place either says they can't mount tires I bought for insurance reasons or they are not interested in mounting them on a BMW or a brand they haven't heard of. :huh Yes I have heard the sidewalls are stiff on these things but really? Thus ends my rant. On a side note since I am taking the wheels in myself should I take off the front rotors or am I ok to leave them on?
