Ok so after a short ride I noticed I had a screw in my front tire

. It's not leaking air, so I pull on the screw and it comes out. It looks like it is just the head of a drywall screw that I ran over. It left a hole in the tire but isn't leaking air. I will post up pics, tell me what you guys think. I am too paranoid to ride with a hole in my tire, but do you guys think it's even safe to ride to the tire place? I apologize for the poor picture quality, cheap camera

.
This is welding wire to give you an idea of the size.
It has been like this for a week now, still hasn't lost air :shrug:.
