Non-pneumatic tire integrated with wheel and method for manufacturing the same

A method for manufacturing a non-pneumatic tire integrated with a wheel, comprising the steps of:

• producing a wheel in which a rim groove is formed at a center portion of a rim and has a reduced diameter, in which rim flanges are respectively formed at both sides of the rim and respectively have protrusions oppositely formed thereon, and in which a supporting rim is formed between the protrusions and the rim;
• forming multi-layers of an elastic layer and a tread layer, in which the non-cured elastic layer is formed to a lower portion of the protrusions of the rim flanges of the wheel, and the non-cured tread layer is formed to cover an upper surface of the elastic layer and the rim flanges;
• and
• curing the non-cured multi-layers in a mold.

• forming a non-cured elastic layer to a lower portion of the protrusions of the rim flanges of the wheel;
• firstly curing the non-cured elastic layer in a mold;
• forming a non-cured tread layer to cover an upper surface of the cured elastic layer and the rim flanges;

• secondly curing the non-cured tread layer in a mold.

A non-pneumatic tire integrated with a wheel, comprising:

• the wheel coupled to an axle of a vehicle and having rim flanges formed at both sides of an outer peripheral surface of a rim, respectively;
• an elastic layer formed on the rim of the wheel;
• and
• a tread layer formed to contact a road, in which the elastic layer is covered with the tread layer;
• wherein the rim of the wheel has a rim groove formed with a diameter that is smaller than that of the outer peripheral surface of the rim, and a part of the elastic layer is inserted in the rim groove on the rim, so as to improve a transverse supporting force of the elastic layer.
