Abstract:
A spike retaining base has a top base surface, a generally vertical aperture defined within it, and a plurality of aperture slots. A base insert includes a central hub and a plurality of insert arms. Each arm is foldable so as to allow the insert base to wrap around the base of a tire puncturing spike. When used, the base insert is positioned above the base aperture and the base of a spike is positioned above the base insert. The spike base and the base insert are urged into the base aperture to the point that the spike and the base insert are lockingly engaged with the base. As a tire engages the spike, a bubble at the hub of the base insert allows the base insert to be forced down into the base aperture thereby releasing the spike from the base.
