A heavy-duty, wear resistent, blow-molded plastic wheel comprising first and second integrally-formed wheel sides defined by alternating axially spaced-apart and joined side segments. A solid center core portion surrounds a central axle bore. The wheel also includes an integrally-formed, axially-extending tread, and molded, integrally-formed axle bore support means in the first and second wheel sides radially-outwardly adjacent of the axle bore and diagonally extending between the first and the second wheel sides to provide enhanced support to the axle bore.
