A one-piece tire has an elastomer material composition that is homogeneous and consistent throughout the entire tire. An annular outer portion of the one-piece tire includes an outwardly facing surface that defines an outer circumference of the tire and a width of the tire between a first edge on a first lateral side and second edge on a second lateral side of the tire. An annular inner portion defines an inner circumference of the tire. The annular inner portion has a first edge on the first lateral side of the tire and a second edge on the second lateral side of the tire. An annular resilient spring portion extends from a first junction near the first edge of the annular inner portion to a second junction near the second edge of the annular outer portion.

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;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; andan 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,whereinthe 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. 2. The tire of claim 1, wherein an entirety of the one-piece body is formed during a single manufacturing process that establishes the annular outer portion, the annular inner portion, and the annular resilient spring portion. 3. The tire of claim 2, wherein the single manufacturing process comprises injection molding, compression molding, casting or three-dimensional printing. 4. The tire of claim 1, wherein the elastomer material comprises rubber. 5. The tire of claim 1, wherein the first junction and the second junction each include a rounded bend. 6. The tire of claim 1, wherein the annular resilient spring portion has a curved profile between the first junction and the second junction. 7. The tire of claim 1, wherein the outwardly facing surface of the annular outer portion defines a ground-engaging tread of the tire. 8. The tire of claim 1, wherein the annular resilient spring portion has a default position in which the annular resilient spring portion is spaced from an inwardly facing surface of the annular outer portion, andat least a section of the annular resilient spring portion flexes under load into a compressed position where the section of the annular resilient spring portion contacts the inwardly facing surface on the annular outer portion. 9. The tire of claim 8, wherein the section of the annular resilient spring portion engages the inwardly facing surface on the annular outer portion in a manner that resists relative lateral movement between the annular resilient spring portion and the annular outer portion. 10. The tire of claim 8, wherein the first junction flexes a first amount in response to the load,the second junction flexes a second amount in response to the load, andthe second amount is greater than the first amount. 11. The tire of claim 8, comprising a stiffening reinforcement between the annular resilient spring portion and the annular inner portion. 12. The tire of claim 11, wherein the stiffening reinforcement comprises a plurality of ribs. 13. The tire of claim 8, wherein the annular resilient spring portion has a single, consistent thickness between the first junction and the second junction, ora varying thickness between the first junction and the second junction. 14. The tire of claim 1, wherein the annular resilient spring portion flexes from a default position into a compressed position in response to a force in a direction perpendicular to an axis of rotation of the tire, andthe annular resilient spring portion deflects at least some of the force in a direction toward one of the lateral sides of the tire. 15. The tire of claim 14, wherein the annular outer portion moves relative to the annular inner portion in a lateral direction in response to the at least some of the force that is deflected. 16. The tire of claim 14, wherein the annular resilient spring portion is configured to establish lines of thrust directed toward the second lateral side. 17. The tire of claim 14, wherein the annular resilient spring portion has a first thickness between the first junction and a midsection of the annular resilient spring portion,the midsection of the annular resilient spring portion has a second thickness,the first thickness is greater than the second thickness,the annular resilient spring portion has a third thickness between the midsection and the second junction, andthe third thickness is greater than the second thickness. 18. The tire of claim 17, wherein the first thickness progressively increases along a direction from the midsection toward the first junction, andthe second thickness progressively increases along a direction from the midsection toward the second junction. 19. The tire of claim 14, wherein the annular inner portion is configured to be secured to a wheel hub. 20. A method of making a tire, the method comprising using a single manufacturing process to establish a one-piece body having an elastomer material composition that is homogeneous and consistent throughout an entirety of the one-piece body, wherein: the one-piece body has an annular outer portion, an annular inner portion, and an annular resilient spring portion;the annular outer portion includes an outwardly facing surface that defines an outer circumference of the tire;the annular outer portion has a first edge on a first lateral side of the tire and second edge on a second lateral side of the tire;the annular inner portion defines an inner circumference of the tire;the annular inner portion has a first edge on the first lateral side of the tire and a second edge on the second lateral side of the tire; andthe annular resilient spring portion extends from a first junction near the first edge of the annular inner portion to a second junction near the second edge of the annular outer portion.
