Non-pneumatic tire
Abstract
Abstract The invention provides a non-pneumatic tire which can improve a riding quality, a noise performance and the like while improving a durability, and can further sufficiently suppress a buckling of a ground portion between spokes, because a circumferential fluctuation of a tire rigidity is hard to be generated due to a positional relationship between a spoke position and a center position of the ground surface, and a strain can be dispersed into each of portions of a support structure body. In a non-pneumatic tire T comprising a support structure body SS supporting a load from a vehicle, the support structure body SS includes an inner annular portion 1 , an intermediate annular portion 2 concentrically provided in an outer side of the inner annular portion 1 , an outer annular portion 3 concentrically provided in an outer side of the intermediate annular portion 2 , a plurality of inner coupling portions 4 coupling the inner annular portion 1 and the intermediate annular portion 2 , and a plurality of outer coupling portions 5 coupling the outer annular portion 3 and the intermediate annular portion 2 , and the number of the outer coupling portions 5 is larger than the number of the inner coupling portions 4.
