Non-pneumatic tire with structural reinforcement member in tread part

A non-pneumatic tire with a wheel assembly, the non-pneumatic tire comprising:

• a rim part configured to be connected to an axle;
• a tread part forming an outer side of the tire in a circumferential direction thereof and configured for being in contact with a ground;
• a spoke part disposed between the rim part and the tread part and including upper arch bodies and lower arch bodies to absorb impacts transmitted from the ground to the tread part;
• and
• a structural reinforcement part disposed in the tread part to perform load support and stress distribution of the spoke part,
• wherein the structural reinforcement part comprises:
• a center body arranged along a circumferential direction of the tread part;
• a plurality of first cord sheet members, each first cord sheet member including a plurality of wires;
• and
• a plurality of second cord sheet members, each second cord sheet member including a plurality of wires,
• wherein the plurality of second cord sheet members are directly wound around the center body at an angle of 40° to 85° to the circumferential direction of the tire and are arranged with a gap therebetween, and
• wherein the plurality of first cord sheet members are wound around on an upper surface of the plurality of second cord sheet members at an angle of −40° to −85° to the circumferential direction of the tire and are arranged with a gap therebetween.
