Sorry if this may have been covered or if this seems obvious to some of you, but this is my first BMW and I have a steep learning curve. And yes, I did try the search function.

Looking to get a few parts, what is a good source some of you have used? Thinking of a hitch, running boards (although some folks say they are a pain), and perhaps some interior items (trim and steering wheel).

Also, winter is coming up and the X5 has brand new Toyo Proxes tires on. Anyone running them in snow/ice? Do they have decent traction? I ultimately would like to get a set of winter tires, but it may be a while until I can locate some OEM 18" rims.

Thanks for the replies.
