When I drive I can hear this noise that sounds like something clicking. It is definitely coming from the front left tire. I don't visually see anything that is wrong with it, but I did notice that on the rim... the very center part where the Porsche logo is... it's like.... loose. I can use my finger and touch it and it kind of makes a noise. I think that may be the culprit.
What I am wondering is... is there any easy way I can "tighten" this thing... and does it mean that there is something more serious/dangerous wrong?
Here is a picture of what I think is causing the noise:
