Since my husband's eyes went bad, I took cake of the repair and maintenance of the car. Yesterday I was at the tire shop to buy new ones to replace the balding tires. It was my first time to witness the repairman man change the tires using a Coats tire machine. It was fascinating to watch and i was actually amazed at how easy it was to take off the tire from the tire rim. I've seen this done when I was young and they don't have the tire changers yet. It took the man a lot of skills to remove the tire using a long flat steel. With the tire machine, even I can do it.
