Non-pneumatic tire comprising cord-reinforced spokes

A non-pneumatic tire comprising

• a radially outer circumferential band portion comprising a tread;
• a radially inner hub portion;
• a supporting structure arranged radially between the band portion and the hub portion, and comprising a radially outer ring portion, a radially inner ring portion, and a plurality of spokes extending from the radially outer ring portion to the radially inner ring portion,
• wherein each of the spokes has a radially inner head portion and a radially outer foot portion, and
• wherein at least two neighboring spokes of the plurality of spokes are reinforced by a common cord reinforcement, wherein said cord reinforcement extends at least from the radially outer foot portion of one of the two neighboring spokes within the one of the two neighboring spokes to the radially inner head portion of said one of the neighboring spokes, and further through the radially inner ring portion into the radially inner head portion of the other spoke of the neighboring spokes and further within the other spoke to a radially outer foot portion of the other spoke.

A method of manufacturing a non-pneumatic tire, the tire comprising

• a radially outer circumferential band portion comprising a tread,
• a radially inner hub portion, and
• a supporting structure comprising a plurality of cord-reinforced spokes extending between the hub portion and the circumferential band portion, wherein said spokes have radially inner head portions and radially outer foot portions;
• and
• wherein the method comprises the steps of:
• Providing mold members for molding at least a circumferential sector of the supporting structure comprising one or more of the spokes;
• Winding a cord reinforcement between radially outer foot portions and radially inner head portions of the one or more of the spokes in the circumferential sector of the supporting structure to be molded;
• and
• Over-molding said cord reinforcement with a polymer composition to obtain the circumferential sector of the supporting structure comprising the one or more of the spokes.
