摘要： A wheel construction (10) including a rim (12), the rim having an inner flange (16) and an outer flange (18), each of the inner flange (16) and the outer flange (18) having a first end (16a, 18a) and a second end (16b, 18b), the first end (16a, 18a) of each of the inner and outer flange (16, 18) being positioned axially outwardly relative to the second end (16b, 18b) of the respective flange (16, 18), the rim (12) further including a central well (20) positioned between the inner flange (16) and the outer flange (18), a pair of bead seats (22, 24), one being positioned adjacent each flange (16, 18), each bead seat (22, 24) having an axially outer end (22a, 24a) which is connected to a second end (16b, 18b) of the respective flange (16, 18) by a flange connecting portion (26, 28), and an axially inner end (22b, 24b) which is connected to one of a pair of side parts (30, 32), each side part (30, 32) being positioned between the central well (20) and one of the inner flange (16) and outer flange (18), and connected to the central well (20) by a well connecting portion (34, 36), the axially outer end (22a, 24a) of each bead seat (22, 24) being positioned radially outwardly relative to the axially inner end (22b, 24b) of the respective bead seat (22, 24), wherein at least one of the inner flange (16) and the outer flange (18) includes an extended portion (17, 19) which extends radially inwardly, such that a free end (17a, 19a) of the extended portion (17, 19) is positioned radially inwardly relative to the first end (16a, 18a) of the respective flange (16, 18), and wherein at least one of the side parts (30, 32) includes a substantially straight portion (38, 40) and a curved portion (42, 44), a first end (38a, 40a) of the straight portion (38, 40) being positioned adjacent the respective bead seat (22, 24), and connected to the respective bead seat (22, 24) by a curved connecting portion (46, 48), and a second end (38b, 40b) of the straight portion (38, 40) being connected to the curved portion (42, 44) of the side part (30, 32) by a first substantially concave surface (50, 52) to provide a first sub-well, and the curved portion (42, 44) of the side part (30, 32) including a second sub-well (54, 56), which is defined by a pair of convex surfaces (58, 60, 62, 64), separated by a second concave surface (66, 68).
