Originally just got the wheels/tires for more aggressive appearance (arch extensions and wider tires) as well as the look of the rim itself.

But after driving on the new wheels/tires for 3 days the car feels more like my buddy's X5 that has Adaptive Drive. It doesn't dive as much in corners, feels like I am riding higher (may be my imagination), and just feels tighter overall.

It is almost like having a different X5 altogether.

Just passing along my experience for any owners with 19" all-seasons who may be considering a set of summer rims/tires. If you can spare the extra money (rims/tires/arch extension are not a cheap upgrade) then I would recommend it. I think you will enjoy your X5 even more.
