X5 spare tire just before installation, tire well view with handle nicely tucked away

Just in case if you have ever wondered what's in that hump above your spare tire ,that contains the air pump for your level control for the rear suspension, staying with the subject of rear level control please note you CAN'T make a proper wheel alignment on the X5 (with level control ) without recalibrating the ride height periodically due to limited (camber) adjustment at the rear suspension, it's very important especially with wider rear tires (lower ride height will destroy the inner side of the rear tires due to excessive rear camber )
