Various exemplary embodiments are provided of wheel assemblies and tires. In one exemplary embodiment, a wheel assembly generally includes first and second wheel pieces attachable to each other. The first and second wheel pieces may include respective first and second rim portions. Each of the first and second rim portions may include an arced portion that defines only a portion of a circumference of a rim, such that the arced portions collectively define the circumference of the rim when the first and second wheel pieces are attached. The first and second wheel pieces may be slidably engagable in a first axial direction that is substantially parallel to a rotational axis of the wheel assembly. The first and second wheel pieces may be slidably disengagable in a second axial direction that is generally opposite the first axial direction.
