Wheel, rim and tire

A wheel (1) comprising a solid tire (2) and a rim (3), the solid tire (2) comprising a rubber base layer (4) with a reduced height (16) extending in circumferential direction of the solid tire (2), an inner circumferential contact surface (8) of the rubber base layer (4) being provided to contact an outer circumferential contact surface (9) of the rim (3), the solid tire (2) upon mounting to the rim (3) being provided to be pulled over the circumferential outer contact surface (9) of the rim (3) along a mounting direction at least partly running along an axial direction of the solid tire (2), the inner and outer contact surface (8, 9) comprising at least one engaging set (10) of a protrusion (11) and a corresponding groove (12) for fixing the position of the solid tire (2) on the rim (3) which extend along a first direction crossing the mounting direction, wherein for each position on the outer contact surface (9) of the rim (3) and the inner contact surface (8) of the solid tire (2), in mounting direction of the solid tire (2), at most one engaging set (10) of the protrusion (11) and the corresponding groove (12) is provided, and wherein the solid tire comprises an outer tread surface extending in circumferential direction of the solid tire, being provided for contacting the ground and having a tread width measured along the axial direction of the solid tire, in that the inner contact surface has an inner contact width measured along the axial direction of the solid tire and in that the inner contact width is larger than the tread width, with opposing upright side faces of the solid tire tapering generally inward from the rubber base layer upward to the outer tread surface.
