A spoke wheel for a straddle-type vehicle includes a rim having an outer peripheral surface on which a tire is mounted and an annular shape, a hub supported by an axle on an inner side of the rim and having a tubular shape, and a plurality of wire spokes connecting the rim to the hub. The rim is formed with a plurality of spoke holes through which the plurality of wire spokes pass and support surfaces receiving head portions of the plurality of wire spokes on one end sides of the plurality of spoke holes. Each of the support surfaces has a groove shape extending in a wheel rotation direction.

The present invention is directed to a non-pneumatic tire comprising a circumferential tread band, spokes arranged radially inwards the tread band, and anchoring rails extending in an axial direction and attached to a radially inner side of the tread band along the circumferential direction. The spokes are slidably mountable to the anchoring rails in the axial direction, connecting the tread band and the spokes by mechanical interlocking. Furthermore, the present invention is directed to a non-pneumatic tire comprising on a radially inner side of a tread band axially extending anchoring portions, and two axially neighboring rows of X-shaped spokes, which are circumferentially shifted relative to each other so that each anchoring portion anchors a radially outer right leg of a spoke in a first row of the axially neighboring rows and a radially outer left leg of a spoke in a second row of neighboring rows of spokes.
