First, no, I can't say as I've heard of that tire problem but doesn't sound right for sure. You might try checking with a different shop or even the dealership. As for posting, you start a thread the same way you did in the Newbie section. Just click on the section of the forum you want to post in and in the upper left, you'll see the "New Thread" button in blue. Just click on that and start your thread.
