I haven't even taken delivery of my X5 yet, so I am unable to look at the door to see if there is a channel. My car is being shipped to me this week from down south. Now I have confirmation that this isn't possible. Thank you. I bought my 22" wheels yesterday, so no I have not even gotten them yet. For the winter, I'll be running my stock 19" wheels with brand new Michelin All-Seasons on them. If those are horrible, I'll score some proper winter tires. Maybe I'll sell the stock wheels and tires and get myself a proper set of winter wheels and tires. I have a lot of time to decide. Weather is just starting to get nice here.
