No one really wants to get a flat tire on their BMW, but hazards in the road, in your driveway, or the parking lot at work can all pose a number of risks to tires. If you end up with a flat tire, it’s a good idea to know how to change it, otherwise you may have to wait around for someone to come and assist you.
Ensure that the spare is inflated properly.
Most BMWs today have full-size spare tires, but that’s not always the case. No matter whether you have a temporary-only spare or a full-size one, make sure that it is inflated properly at all times.
Remove the spare tire and take out the jack.
The jack will most likely be a scissor jack that you will need to remove from the trunk of your BMW.
Get the car to a level surface.
Move your BMW to a level surface if it’s not there now. If the tire is completely flat or shredded, you may need to call a tow surface if the car cannot be moved to a flat surface.
Engage the brakes.
Engage the emergency brakes and make sure that the car is in ‘park.’
Loosen the lug nuts.
Before you raise the car, loosen the wheel lug nuts. This may require quite a bit of force. Do not remove the wheel lug nuts yet, just loosen them.
Lift the car up using the scissor jack.
Just behind the front wheels and just in front of the rear wheels you’ll find a point where the jack will sit when lifting the BMW. Refer to the owner’s manual to be sure where to position the jack.
Using the handle on the jack, raise the vehicle.
Once the wheel is off the surface of the ground then remove the lug nuts, the tire, and then place the spare on the wheel, aligning the holes in the tire with the mounting bolts.
Reverse the process, tighten the lug nuts securely, and then get to an authorized BMW service repair center to have your original tire replaced.
