A non-pneumatic tire includes a wheel portion, a tread ring portion, a plurality of flexible spokes extending between and attached to the wheel portion and the tread ring portion, and plurality of bump stops positioned between the wheel portion and the tread ring portion. The bumps stops are configured to limit deformation and/or compressive strain of the plurality of flexible spokes. The plurality of bump stops includes a plurality of tower bump stops, a plurality of triangular-shaped bump stops, and/or a plurality of roof-top shaped bump stops.

An exemplary method of manufacture for a spoke (100) of a non-pneumatic wheel. The spoke can be manufactured with a reinforcement structure having reinforcement elements and one or more layers of material. The spoke can also be provided in various shapes and configurations. The spoke includes anchors (112, 114) that allow the spoke to be more readily incorporated into, or removed from, a non-pneumatic wheel. More particularly, the anchors also allow the spoke to be joined as one-piece with the non-pneumatic wheel or releasably connected on one or both ends with the non-pneumatic wheel.

This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be less than the average thickness (T2) of the rim part. In other words, the relation T1<T2 holds.
