Removing a tubeless tire from a car rim can be dangerous if it is not done properly. You need the right tools and the right procedure to get the job done safely and correctly. There are several steps you need to take before you start prying the tire from the rim, and among those steps is making sure the tire is ready to be removed. You should wear protective leather gloves, goggles and clothing that covers your arms and legs in order to do this job properly.
Place the tire on a flat and solid surface such as a work bench or a concrete floor. The tire should not be hanging over the edges of the surface it is sitting on, and the surface cannot be rocking or moving in any way.
Mix a gallon of warm water and one cup of oil soap into a bucket.
Use a sponge to clean the tire completely. Be sure to remove all debris, especially debris that may be large enough to be a dangerous projectile if something were to go wrong.
Dry the tire with a towel, and also run the towel over the metal rim to remove any debris from the rim.
Use a screwdriver on the stem of the tire to allow all of the air to release from the tire. It is important to get all of the air out of the tire in order to safely remove the tire from the rim. One way of checking to see if all of the air has been removed is to submerge the tire in a tub of water and then apply the screwdriver to the stem. If you do not see air bubbles then the tire is empty.
Run a tire seam tool along both sides of the tire to break the seam. You may want to run the tool over both sides of the tire two or three times to make sure the seal is properly broken. If you are looking to salvage the tire then be careful to not cut the tire with the seam breaking tool.
Pry a tire iron in between the rim and the tire, and begin slowly working the tire back and forth until it releases from the rim. Move the tire iron around the rim to separate the tire from the rim completely.
