Sorry it took so long to get back, but I have some good and bad news.

First is the good news: nothing wrong with my rim or tire. I have been driving on it since I have had it checked out, and it is fine.

Bad news: The steering wheel still needs to be slightly turned CCW in order to go straight. Any ideas on what it could be and how I can check it?

 

Front end alignment should correct that if they make sure the wheel is centered before they start.
