As NoI4Plz noted, there is no spare tire, and no place to carry a spare tire, if you have 3rd row. No jack either. If you venture far out of LV you will want to be certain your AAA or other roadside assistance plan can get to you with a flatbed. (RFT's do fail, and can only be driven for a relatively short distance when they lose air pressure).
And if you are thinking about taking the X5 off pavement, you should consider carrying a full size spare (not a donut), plus a floor jack (not the silly BMW scissors jack you didn't get with the car, anyway).
