I had a set of BF Goodrich tires years ago. They were great, except one went out of round on me. Took it in and they did the same thing. Told me my rim was bent. While on the machine they told me what I was seeing was the rim, but all that was moving was the tire. They refused to replace it. Went to a tire dealer just down the road, had them look at it. They came back and said the tire had failed. To say the least, I don't do business with the other shop anymore, even though the Assistant Manager was a good friend at the time.
