How to Replace Tires on a BMW 325iX

1. Park your BMW on a flat surface.
2. Open the trunk and lift the floor panel to access the jack and wheel wrench. Unscrew the wing nuts by hand that secure the tools in the trunk.
3. Pull off the wheel cover if you have one. You can pull the cover off by hand.
4. Unscrew the wheel nuts with the wheel wrench. Do not remove the wheel nuts at this time.
5. Locate the jacking point under the frame of the car and place the jack head directly under the point. For front tires, the jacking point is behind the front wheelwell. The jacking point for the rear tires is in front of the rear wheelwell. There is an indentation in the frame where the jack head fits when the car is raised.
6. Raise the vehicle with the jack. Make sure there is enough space to easily slide the old tire off and the new tire onto the wheel.
7. Unscrew the wheel nuts by hand and remove them.
8. Pull off the old tire.
9. Line up the holes in the new tire with the bolts on the wheel and slide it on.
10. Screw the wheel nuts onto the new tire by hand. Tighten them enough to hold the tire onto the wheel.
11. Lower the car back to the ground with the jack then remove the jack from under the car.
12. Screw on the wheel nuts with the wheel wrench.
13. Replace the wheel cover.
14. Repeat Steps 3 through 13 for the remaining tires.
