Peace, mercy, and blessings of God be upon you. There is a tire changer tool that runs on the car's cigarette lighter. It is of excellent quality and very strong. You have the right to test it before buying. The price is 120 per piece. Before you come to test, tie the tire screws with the tire shop and come test. Some say you have to loosen the tire screw so it comes off immediately. I say it will come off even if you tightened it. Apparently, only one is left.
