1. A heavy-duty integrally formed wear resistant, blow-molded plastic wheel comprising:
- (a) an integrally-formed circular web defining a central axle bore;
(b) two radially extending peripheral side walls having a plurality of axially spaced-apart spokes alternating with a plurality of axially-joined webs of increased pressure resistance extending radially outwardly from adjacent the axle bore;
(c) an axially extending tread integrally formed with said side walls and connecting said side walls round the peripheral edge of the wheel;
(d) an integrally-formed, axially-extending tread, and molded, integrally-formed axle bore support means in said first and second wheel sides radially-outwardly adjacent to said axle bore and diagonally extending between said first and the second wheel sides to provide enhanced support to said axle bore.
