A non-pneumatic tire may include a hub configured to be coupled to a machine, with the hub having a rotational axis about which the tire is configured to roll. The tire may also include a support structure including an inner circumferential portion associated with the hub and an outer circumferential portion radially spaced from the inner circumferential portion. The support structure may extend between opposed, axially-spaced side edges of the tire, and the support structure may include a plurality of cavities. The tire may also include a tread portion associated with the outer circumferential portion. The support structure may also include a plurality of layers of elastomeric material each having opposing faces lying in opposing planes substantially perpendicular to the rotational axis. At least some of the layers may include apertures corresponding to the cavities, and the layers may be chemically bonded to one another.
