At a guess the screw is all the way through. Looking at the tyre (the wear), and the location of the screw I'd say there isn't much rubber left. New tyre will make the bike handle better.
EDIT: When the tyre is off feel how little rubber there is between the carcass and the tread in the middle compared to the outer. The center will feel alot more flexible.
