Tire Stud Removal Tool with Different Fulcrum Points for Use on Tires of Varying Tread Wear
First Claim
1. A tool for removing studs from a tire, the tool comprising:
- an elongated shaft extending in a longitudinal direction along a longitudinal axis;
a handle attached to the elongated shaft at first end thereof;
a working tip on the elongated shaft at a second end thereof lying opposite the first end in the longitudinal direction;
a hollow socket extending axially into the working tip in the longitudinal direction from a free end of the working tip that lies opposite the handle in the longitudinal direction;
a first fulcrum point carried on the shaft at a first radial distance outward from the shaft and at a first axial distance in the longitudinal direction from the free end of the working tip; and
a second fulcrum point carried on the shaft at a second radial distance outward from the shaft and at a second axial distance in the longitudinal direction from the free end of the working tip, the second axial distance between greater than the first axial distance so as to situate the second fulcrum point further form the free end of the working tip than the first fulcrum point.

Abstract
A tire stud removal tool features a handle and working tip attached to opposing ends of a shaft, and a hollow socket at a free end of the working tip. At least one fulcrum member protrudes outwardly from the elongated shaft at a position adjacent to the working tip. The one or more fulcrum members define a first fulcrum point nearer to the free end of the working tip for leveraging the tool against the pliable tread of generally unworn studded tire, and the second fulcrum point further from the working tip for leveraging the tool against the stiffer tread of a notably worn studded tire. The second fulcrum point resides at an outer end of a sloped surface that faces toward the free end of the working tip and slopes away from the free end of the working tip toward the handle in an outward direction.
