When replacing a tire on the side of the road in the hood, it is common courtesy to leave your discarded tire by the side of the road so that, in an emergency, future motorists can use it. This is why there are so many seemingly abandoned tires along hood roads. Also, those who are in on the secret, use these tires as markers. They indicate safe haven for hood occupants.
Each tire typically has a protection radius of approximately one mile. So the hood tires also serve as makeshift mile markers.
