Abstract
A retractable stud pin assembly is described for use in a conventional tire. The stud pin assembly includes a housing having an elastomer compartment and a spring in cooperation with the elastomer. A stud pin is mounted to the spring. The assembly may further optionally include a fluid compartment in cooperation with the elastomer compartment and the spring. The assembly may further include a second compression spring, which cooperates with the first spring and stud pin. An optional adjustment nut may be used to manually raise and lower the pin height as desired. An optional adjustment pin may also be used to extend into an optional fluid compartment to fine tune the pin height.
