Claim 23:
24. A gauge wheel tire, comprising:
a first polyurethane sidewall portion;
a second polyurethane sidewall portion spaced apart from the first polyurethane sidewall portion;
a polyurethane ground-engaging portion extending from the first polyurethane sidewall portion to the second polyurethane sidewall portion and adapted to contact a ground surface as the gauge wheel tire rotates about an axis of rotation; and
a polyurethane axial support portion extending from the first polyurethane sidewall portion to the second polyurethane sidewall portion, wherein the polyurethane axial support portion is spaced apart from the polyurethane ground-engaging portion to form a gap that allows radial movement of the polyurethane ground-engaging portion relative to the polyurethane axial support portion, wherein:
the polyurethane axial support portion comprises at least one protrusion that extends radially upward into the gap to inhibit the polyurethane ground-engaging portion from moving radially inward beyond a height of the at least one protrusion, and
the at least one protrusion cannot be separated from the polyurethane axial support portion without damaging the polyurethane axial support portion.
