Claim 1
Independent Claim
300 words
A tire package having an axis of rotation and comprising: a. an uninflated tire having a pair of annular bead portions, each said bead portion having a radially inner surface of a predetermined axial width that is oriented at a predetermined angle of between about 5° and about 15° with respect to said axis, each said bead portion further comprising an axially outer surface extending in a generally radial direction, projections of the radially inner and axially outer surfaces of said bead portions intersecting one another at the sharp diameter of the bead portions; b. a pair of annular plastic bead protectors, each of said bead protectors being slideably inserted inside a bead portion of said tire, each said bead protector comprising an annular bead seat with a generally radially extending flange located at the axially outermost end of the bead seat with respect to said tire package, the bead seat of each bead protector having a radially outer surface that is adjacent to the radially inner surface of a bead portion of said tire with the flange having an axially inner surface that is adjacent to the axially outer surface of the bead portion of the tire, the radially outer surface of the bead seat of each bead protector being oriented at substantially the same angle with respect to said axis as the radially inner surfaces of the bead portions of said tire, projections of the radially outer surfaces of said bead seats and axially inner surfaces of said flanges intersecting one another at a sharp diameter that is in the range of 0.0 to 3.75 millimeters less than the sharp diameter of the bead portions of said tire; and c. a plurality of elastic tension members exerting an axially inwardly directed force on each of said bead protectors.

A tire package having an axis of rotation and comprising: a. an uninflated tire having a pair of annular bead portions, each said bead portion having a radially inner surface of a predetermined axial width that is oriented at a predetermined angle of between about 5° and about 15° with respect to said axis, each said bead portion further comprising an axially outer surface extending in a generally radial direction, projections of the radially inner and axially outer surfaces of said bead portions intersecting one another at the sharp diameter of the bead portions; b. a pair of annular plastic bead protectors, each of said bead protectors being slideably inserted inside a bead portion of said tire, each said bead protector comprising an annular bead seat with a generally radially extending flange located at the axially outermost end of the bead seat with respect to said tire package, the bead seat of each bead protector having a radially outer surface that is adjacent to the radially inner surface of a bead portion of said tire with the flange having an axially inner surface that is adjacent to the axially outer surface of the bead portion of the tire, the radially outer surface of the bead seat of each bead protector being oriented at substantially the same angle with respect to said axis as the radially inner surfaces of the bead portions of said tire, projections of the radially outer surfaces of said bead seats and axially inner surfaces of said flanges intersecting one another at a sharp diameter that is in the range of 0.0 to 3.75 millimeters less than the sharp diameter of the bead portions of said tire; and c. a plurality of elastic tension members exerting an axially inwardly directed force on each of said bead protectors.
Claim 3
Dependent Claim
102 words
A tire package as described in claim 1 wherein the radially outer surface of the bead seat of each bead protector has an axial width that is greater than the axial width of the radial inner surfaces of the bead portions of said tire, the bead seat of each bead protector having a plurality of circumferentially spaced apart holes extending therethrough located axially inwardly of the radially inner surface of the respective bead portion of said tire, and said elastic tension members being secured to each of said bead protectors by a means for fastening that extends through one of said holes.
Claim 4
Dependent Claim
16 words
A tire package as described in claim 1 wherein said bead protectors are comprised of polyethylene.
Claim 5
Dependent Claim
16 words
A tire package as described in claim 2 wherein said bead protectors are comprised of polyethylene.
