1. A tire comprising:
a one-piece body having an elastomer material composition, the one-piece body including:
an annular outer portion including an outwardly facing surface that defines an outer circumference of the tire, the annular outer portion defining a width of the tire between a first edge on a first lateral side of the tire and second edge on a second lateral side of the tire, the annular outer portion defining a cavity;
an annular inner portion that defines an inner circumference of the tire, the annular inner portion having a first edge on the first lateral side of the tire and a second edge on the second lateral side of the tire; and
an annular resilient spring portion extending between a first junction near the first edge of the annular inner portion and a second junction near the second edge of the annular outer portion;
wherein the elastomer material composition of the annular outer portion, the annular inner portion, and the annular resilient spring portion is homogeneous and consistent throughout an entirety of the one-piece body;
wherein the annular resilient spring portion is frustoconical;
wherein when the tire is in an uncompressed state, at least the second edge of the annular inner portion is disposed within the cavity;
wherein as the annular resilient spring portion extends towards the second edge of the annular outer portion, the annular resilient spring portion extends beyond an axial position of the second edge of the annular inner portion; and
wherein the first edge of the annular inner portion is closer to an axial position of the first edge of the annular outer portion than to an axial position of the second edge of the annular outer portion.
