I know I'm late to the party on this thread, but just picked up a 2011 X5 50i. So I guess I'll be the FNG for a while....

Right now I have 19" rims with all seasons, and wanted to go to 20" with performance tires for the summer.

Just curious whether or not you installed the wider flares yourself....or if anyone else on the thread has, if they could provide insight on the difficulty level.

Thanks!
