This tire changing tool is an easy to use, portable tool. It can be used on front, and backwheel, since it can be fixed to the brake disc. The tool doesnt require any kind of external fixing, so if the individual wants, it can be used even lifted in the air. It can be used on different sized wheels, with different size brake discs, with different (z) distance between the rim, and the brake, and between the brake and the main axis. It is easy, and fast to deploy, and if its not in use, it can be stored in more parts, so it need less place.
How to use:
Step 1: Put the main rod inside the wheels center.
Step 2: Fasten the brake to the brake disc.
Step 3: Put the end part under the tire.
Step 4: Fix it to the arm.
Step 5: Rotate the handle.
