1. A wheel comprising: a plurality of rim portions; anda plurality of wheel sections, each wheel section comprising a hub defining a rotational axis and at least one spoke attached to the hub, the at least one spoke extending from the hub to a corresponding one of the rim portions and being attached
1. A wheel comprising: a plurality of rim portions; anda plurality of wheel sections, each wheel section comprising a hub defining a rotational axis and at least one spoke attached to the hub, the at least one spoke extending from the hub to a corresponding one of the rim portions and being attached to the rim portion, the plurality of wheel sections configured to be rotatable relative to each other from a collapsed position to an expanded position about the rotational axis, wherein in the collapsed position the at least one spoke of each wheel section is radially spaced at a first angle relative to the at least one spoke of an adjacent wheel section, and wherein in the expanded position the at least one spoke of each wheel section is radially spaced relative to the at least one spoke of an adjacent wheel section at a second angle greater than the first angle. 2. The wheel of claim 1, wherein the wheel sections are substantially fixed from rotation relative to each other in the expanded position. 3. The wheel of claim 1, wherein in the collapsed position the rim portions of the plurality of wheel sections radially span less than 360 degrees, and wherein in the expanded position the rim portions of the plurality of wheel sections define a circular band. 4. The wheel of claim 1, further comprising a tire configured to be mountable on the rim portions in the collapsed position or the expanded position. 5. The wheel of claim 1, wherein each rim portion comprises a tire portion. 6. The wheel of claim 1, each wheel section comprising a radially configured slot and a pin configured to be received in the slot of another wheel section, wherein movement of the pin of one wheel section inside the slot of an adjacent wheel section defines a range of rotation of the one wheel section relative to the adjacent wheel section. 7. The wheel of claim 1, wherein the plurality of wheel sections define groups of wheel sections with each group comprising a pair of the wheel sections, and wherein the spokes of the wheel sections of each pair of wheel sections extend from the hub of the corresponding wheel section to the same rim portion. 8. The wheel of claim 1, wherein the rim portions substantially define a path on a circumferential band around the wheel sections in the expanded position. 9. The wheel of claim 1, further comprising an axle configured to removably receive the hub of each wheel section by being insertable in a central bore of each wheel section being coaxial with the rotational axis of the wheel section, wherein each wheel section is rotational relative to the axle. 10. A method of manufacturing a wheel comprising: forming plurality of rim portions; andforming a plurality of wheel sections, each wheel section comprising a hub defining a rotational axis and at least one spoke attached to the hub, the at least one spoke extending from the hub to a corresponding one of the rim portions and being attached to the rim portion, the plurality of wheel sections configured to be rotatable relative to each other from a collapsed position to an expanded position about the rotational axis, wherein in the collapsed position the at least one spoke of each wheel section is radially spaced at a first angle relative to the at least one spoke of an adjacent wheel section, and wherein in the expanded position the at least one spoke of each wheel section is radially spaced relative to the at least one spoke of an adjacent wheel section at a second angle greater than the first angle. 11. The method of claim 1, further comprising forming a locking mechanism configured to substantially fix the wheel sections from rotating relative to each other in the expanded position. 12. The method of claim 1, wherein in the collapsed position the rim portions of the plurality of wheel sections radially span less than 360 degrees, and wherein in the expanded position the rim portions of the plurality of wheel sections define a circular band. 13. The method of claim 1, further comprising forming a tire configured to be mountable on the rim portions in the collapsed position or the expanded position. 14. The method of claim 1, forming tire section on each rim portion. 15. The method of claim 1, further comprising forming a radially configured slot and a pin on each wheel section, the pin configured to be received in the slot of another wheel section, wherein movement of the pin of one wheel section inside the slot of an adjacent wheel section defines a range of rotation of the one wheel section relative to the adjacent wheel section. 16. The method of claim 1, further comprising forming the plurality of wheel section such that the spokes of two wheel sections extend from the hub of the corresponding wheel sections to the same rim portion. 17. The method of claim 1, wherein the rim portions substantially define a path on a circumferential hand around the wheel sections in the expanded position. 18. A cart for a golf club bag comprising: a frame configured to support a golf club bag; anda pair of wheels coupled to the frame, each wheel comprising: a plurality of rim portions; anda plurality of wheel sections, each wheel section comprising a hub defining a rotational axis and at least one spoke attached to the hub, the at least one spoke extending from the hub to a corresponding one of the rim portions and being attached to the rim portion, the plurality of wheel sections configured to be rotatable relative to each other from a collapsed position to an expanded position about the rotational axis, wherein in the collapsed position the at least one spoke of each wheel section is radially spaced at a first angle relative to the at least one spoke of an adjacent wheel section, and wherein in the expanded position the at least one spoke of each wheel section is radially spaced relative to the at least one spoke of an adjacent wheel section at a second angle greater than the first angle. 19. The cart of claim 18, wherein the wheel sections are substantially fixed from rotation relative to each other in the expanded position. 20. The cart of claim 18, wherein in the collapsed position the rim portions of the plurality of wheel sections radially span less than 360 degrees, and wherein in the expanded position the rim portions of the plurality of wheel sections define a circular band. 21. The cart of claim 18, further comprising a tire configured to be mountable on the rim portions in the collapsed position or the expanded position. 22. The cart of claim 18, wherein each rim portion comprises a tire portion. 23. The cart of claim 18, each wheel section comprising a radially configured slot and a pin configured to be received in the slot of another wheel section, wherein movement of the pin of one wheel section inside the slot of an adjacent wheel section defines a range of rotation of the one wheel section relative to the adjacent wheel section. 24. The cart of claim 18, wherein the plurality of wheel sections define groups of wheel sections with each group comprising a pair of the wheel sections, and wherein the spokes of the wheel sections of each pair of wheel sections extend from the hub of the corresponding wheel section to the same rim portion. 25. The cart of claim 18, wherein the rim portions substantially define a path on a circumferential band around the wheel sections in the expanded position. 26. The cart of claim 18, further comprising an axle configured to removably receive the hub of each wheel section by being insertable in a central bore of each wheel section being coaxial with the rotational axis of the wheel section, wherein each wheel section is rotational relative to the axle.
