I was losing pressure in both of my rear wheels. The technician came to my house and said both my rear tires were worn so badly that they both needed to be replaced. And he added that the reason they had worn was because they had not been rotated and that should have be done every 3 to 5 thousand miles. In 4,000 miles my left rear tire kept loosing pressure. Another technician came and the tire had a nail in it. It too had begun to wear more than usual. I told the tech that they probably were due to be rotated. He said you never rotate the tires because the front and back are different sizes. Again another nerve tire. Has anyone else had what I would call “a run around “ about their tires?
