a second tire mounting portion (161a, 162a, 165a) located and spaced apart from the first tire mounting portion (161, 162, 164, 165) and including a second bead seat coming into contact with an inner bead of the tire; and a well portion including an outer well portion extending from the first tire mounting portion (161, 162, 164, 165), and an inner well portion configured to connect the outer well portion to the second tire mounting portion (161a, 162a, 165a), wherein a thickness is formed to be thinner in an order of the outer well portion, the second bead seat, and the inner well portion, wherein the thickness of the outer well portion is 1.2 to 1.8 times that of the second bead seat, and wherein the thickness of the outer well portion is 1.2 to 2.5 times that of the inner well portion, wherein the inner well portion is formed to be inclined in an outward direction of the outer well portion based on a rotational center of the disc member, wherein the inner well portion is formed to be inclined in multi-stepped stages, wherein the inner well portion includes: a first inclined portion (163b-1) formed to be inclined from the outer well portion to the second bead seat; and a second inclined portion (163b-2) formed to be inclined from the second bead seat to the first inclined portion (163b-1) and connected to the first inclined portion (163b-1), characterized in that an inclined angle between the bottom surface of the second bead seat and the second inclined portion (163b-2) is the same as a slope angle between the rotational center line of the disc member and the second inclined portion (163b-2). a disc member to which an axle is connected; and a rim portion connected to the disc member and on which a tire is mounted, wherein the rim portion includes: a first tire mounting portion (161, 162, 164, 165) connected to the disc member and including a first bead seat coming into contact with an outer bead of the tire; a second tire mounting portion (161a, 162a, 165a) located and spaced apart from the first tire mounting portion (161, 162, 164, 165) and including a second bead seat coming into contact with an inner bead of the tire; and a well portion including an outer well portion extending from the first tire mounting portion (161, 162, 164, 165), and an inner well portion configured to connect the outer well portion to the second tire mounting portion (161a, 162a, 165a), wherein a thickness is formed to be thinner in an order of the outer well portion, the second bead seat, and the inner well portion, wherein the thickness of the outer well portion is 1.2 to 1.8 times that of the second bead seat, and wherein the thickness of the outer well portion is 1.2 to 2.5 times that of the inner well portion, wherein the inner well portion is formed to be inclined in an outward direction of the outer well portion based on a rotational center of the disc member, wherein the inner well portion is formed to be inclined in multi-stepped stages, a first tire mounting portion (161, 162, 164, 165) connected to the disc member and including a first bead seat coming into contact with an outer bead of the tire; a second tire mounting portion (161a, 162a, 165a) located and spaced apart from the first tire mounting portion (161, 162, 164, 165) and including a second bead seat coming into contact with an inner bead of the tire; and a well portion including an outer well portion extending from the first tire mounting portion (161, 162, 164, 165), and an inner well portion configured to connect the outer well portion to the second tire mounting portion (161a, 162a, 165a), wherein a thickness is formed to be thinner in an order of the outer well portion, the second bead seat, and the inner well portion, wherein the thickness of the outer well portion is 1.2 to 1.8 times that of the second bead seat, and wherein the thickness of the outer well portion is 1.2 to 2.5 times that of the inner well portion, wherein the inner well portion is formed to be inclined in an outward direction of the outer well portion based on a rotational center of the disc member, wherein the inner well portion is formed to be inclined in multi-stepped stages, wherein the inner well portion includes: a first inclined portion (163b-1) formed to be inclined from the outer well portion to the second bead seat; and a second inclined portion (163b-2) formed to be inclined from the second bead seat to the first inclined portion (163b-1) and connected to the first inclined portion (163b-1), characterized in that an inclined angle between the bottom surface of the second bead seat and the second inclined portion (163b-2) is the same as a slope angle between the rotational center line of the disc member and the second inclined portion (163b-2). a first inclined portion (163b-1) formed to be inclined from the outer well portion to the second bead seat; and a second inclined portion (163b-2) formed to be inclined from the second bead seat to the first inclined portion (163b-1) and connected to the first inclined portion (163b-1), characterized in that an inclined angle between the bottom surface of the second bead seat and the second inclined portion (163b-2) is the same as a slope angle between the rotational center line of the disc member and the second inclined portion (163b-2).
