A wheelbarrow that incorporates a stand coupled to a tub, a handle at the distal end of the wheelbarrow, and a wheel mount at the proximal end of the wheelbarrow. A wheel is rotatably coupled to the wheel mount and comprises a rim surrounded by a non-pneumatic tire. The tire has a mounting region and an expanded region. The axial width of the expanded region is substantially greater than the axial width of the mounting region and the tire has a relatively flat tread surface.

What is claimed is: 1. A wheelbarrow comprising: a stand coupled to a tub, a handle at the distal end of the wheelbarrow, and a wheel mount at the proximal end of the wheelbarrow; and a wheel rotatably coupled to the wheel mount; the wheel comprising a rim having an axial width and a non-pneumatic
What is claimed is: 1. A wheelbarrow comprising: a stand coupled to a tub, a handle at the distal end of the wheelbarrow, and a wheel mount at the proximal end of the wheelbarrow; and a wheel rotatably coupled to the wheel mount; the wheel comprising a rim having an axial width and a non-pneumatic tire surrounding the rim in the radial direction of the wheel, wherein the tire comprises a mounting region and an expanded region, wherein the radial spacing of the expanded region is greater than the radial spacing of the mounting region, wherein the axial width of the expanded region is substantially greater than the axial width of the mounting region, the expanded region having sidewalls and a tread surface having an axial width, the sidewalls being substantially perpendicular to the tread surface, and the tread surface axial width being substantially greater than the rim axial width, and the tread surface having a substantially constant radial distance from the axis of the wheel to stabilize the wheelbarrow. 2. The wheelbarrow of claim 1, wherein the maximum axial width of the expanded region in the axial direction of the tire is constant. 3. The wheelbarrow of claim 2, wherein the maximum axial width of the mounting region is equal to the maximum axial width of the rim. 4. The wheelbarrow of claim 3, wherein the tire further comprises a transition region between the mounting region and the expanded region in the radial direction of the wheel. 5. The wheelbarrow of claim 4, wherein the transition region is of increasing axial width as it transitions from the mounting region to the expanded region in an increasing radial direction. 6. The wheelbarrow of claim 5, wherein a plurality of grooves are formed within the tread surface and are separated by a plurality of ribs. 7. The wheelbarrow of claim 6, wherein the plurality of grooves are noncontiguous and the plurality of ribs are non-contiguous. 8. The wheelbarrow of claim 7, wherein the plurality of ribs comprises surfaces that maintain a substantially constant radial distance from the axis of the wheel. 9. The wheelbarrow of claim 8, wherein the surfaces of the plurality of ribs are at a substantially constant radial distance from the axis of the wheel over the entire axial spacing of the grooves. 10. The wheelbarrow of claim 9, wherein the width of the tread surface in the axial direction is equal to the width of the expanded region in the axial direction. 11. The wheelbarrow of claim 10, wherein the tire is made of a solid material. 12. A wheelbarrow comprising: a stand coupled to a tub, a handle at the distal end of the wheelbarrow, and a wheel mount at the proximal end of the wheelbarrow; and a wheel rotatably coupled to the wheel mount; the wheel comprising a rim having an axial width, and a non-pneumatic tire surrounding the rim in the radial direction of the wheel, wherein the tire has sidewalls and a tread surface having an axial width, the sidewalls being substantially perpendicular to the tread surface, the tread surface axial width being substantially greater than the rim axial width, and the tread surface having a substantially constant radial distance from the axis of the wheel to stabilize the wheelbarrow. 13. The wheelbarrow of claim 12, wherein the maximum axial width of the tire is equal to the axial width of the tread surface. 14. The wheelbarrow of claim 13, wherein a plurality of grooves are formed within the tread surface and are separated by a plurality of ribs. 15. The wheelbarrow of claim 14, wherein the plurality of ribs comprises surfaces that are a substantially constant radial distance from the axis of the wheel over the entire axial spacing of the grooves. 16. The wheelbarrow of claim 15, wherein the tread surface is formed in an expanded region. 17. The wheelbarrow of claim 16, wherein the axial width of the expanded region is constant. 18. The wheelbarrow of claim 17, wherein the axial width of the expanded region is equal to the axial width of the tread surface. 19. The wheelbarrow of claim 18, wherein the tire further comprises a transition region; wherein the expanded region lies at a radial distance from the axis of the wheel greater than the transition region; wherein the transition region increases in axial width with increasing radial distance from the axis of the wheel.
