Solution

1. Preparation

Tools Required: Jack, lug wrench, tire pressure gauge, portable air compressor (if applicable), tire repair kit or spare tire, gloves.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Put on safety gloves to protect your hands.

2. Loosen Lug Nuts

Use the lug wrench to slightly loosen the lug nuts on the flat tire while it is still on the ground.
Turn the lug nuts counterclockwise to avoid any damage to the nuts.

3. Lift the Vehicle

Position the jack under the designated jacking point of the vehicle (refer to the owner’s manual for the exact location).
Raise the vehicle until the tire is off the ground.

4. Remove the Flat Tire

Fully unscrew the loosened lug nuts and remove them from the wheel.
Carefully take off the flat tire and set it aside.

5. Repair or Replace the Tire

If Repairing:
- Use a tire repair kit to patch the puncture (follow the kit's instructions).
- Apply tire sealant if necessary and allow it to cure as per the manufacturer’s direction.
If Replacing:
- Install the spare tire or a new tire, ensuring it matches the specifications for the BMW 3 Series F30/F31.

6. Reinstall the Wheel

Place the tire onto the hub and hand-tighten the lug nuts onto the wheel studs.
Use the lug wrench to tighten the lug nuts in a crisscross pattern to ensure even tightening.

7. Lower the Vehicle

Carefully lower the vehicle back to the ground using the jack.
Once the vehicle is fully on the ground, tighten the lug nuts to the manufacturer’s specified torque (usually around 80-100 ft-lbs).

8. Final Checks

Check the tire pressure using a tire pressure gauge and inflate if necessary.
Store the flat tire and tools back in the vehicle.
