Non-pneumatic tire

A non-pneumatic tire comprising

• a circumferential tread portion;
• and
• a supporting structure comprising a radially inner circumferential hub portion, a radially outer circumferential ring portion supporting the tread portion, and a plurality of spokes arranged between the ring portion and the hub portion to support the ring portion on the hub portion,
• wherein at least one of the spokes has an essentially X-shaped cross-section and comprises a pair of radially inner legs and a pair of radially outer legs connected to each other in a crossing portion of the at least one of the spokes,
• wherein the pair of radially outer legs comprises a foot portion adjacent to the radially outer ring portion, and wherein the pair of radially inner legs comprises a head portion adjacent to the radially inner hub portion,
• wherein at least one of the foot portion and the head portion comprises a first elastomer composition having a first stiffness;
• and
• wherein the at least one of the spokes comprises a second elastomer composition between the foot portion and the crossing portion, and wherein the second elastomer composition has a second stiffness which is at least 5% lower than the first stiffness of the first elastomer composition.
