Abstract
A hardness testing device for a bicycle tire has a body with a surface thereon, an arm having a protrusion extending outwardly of the surface, a spring cooperative with a portion of the arm for resisting movement of the protrusion inwardly of the body when the protrusion contacts a surface of the tire, and an indicator cooperative with the arm for providing a humanly perceivable indication of movement of the protrusion relative to a hardness of the tire. The arm is pivotally mounted in or on the body.

A hardness testing device for a tire comprising:
- a body having a surface thereon;
- an arm having a protrusion extending outwardly of said surface, said arm mounted in or on said body;
- a spring means cooperative with a portion of said arm, said spring means for resisting movement of said protrusion inwardly of said body when said protrusion contacts a surface of the tire;
- and
- an indicator means cooperative with said arm, said indicator means for providing a humanly perceivable indication of a movement of said protrusion relative to a hardness of the tire, said surface of said body being an arcuate surface generally matching a curvature of the tire.
A hardness testing device for a tire comprising:
- a body having a surface thereon;
- an arm having a protrusion extending outwardly of said surface, said arm mounted in or on said body;
- a spring means cooperative with a portion of said arm, said spring means for resisting movement of said protrusion inwardly of said body when said protrusion contacts a surface of the tire;
- and
- an indicator means cooperative with said arm, said indicator means for providing a humanly perceivable indication of a movement of said protrusion relative to a hardness of the tire, said surface of said body having an indentation formed thereat, said protrusion extending outwardly of said indentation.
