I had tires replaced yesterday due to the Michelin recall. Asked them to put the braided tire value extensions on the inside rear wheels. I think I have a problem. There was a u clamp attached to the braided extension, but they did not attach it to my wheel simulators. The clamp is pretty heavy and I'm concerned going down the highway that it will constantly be swinging around. I removed the U clamp since it wasn't attached so now the extension is hanging freely. Aren't they supposed to be attached to simulator somehow or is it OK to have them moving freely?
