Abstract
A molded plastic wheel having an integrally formed axle retainer which mates to an annular axle groove. In a blow molded wheel construction, a number of flexible tabs radially project into an axle bore. A portion of each tab is acutely displaced to the bore walls adjacent to a region of relief which facilitates tab flexion. The tabs are die cut from flashed material at the bore. Internal trusses formed intermediate external traction lugs at the tread to sidewall transition stabilize the wheel rim.
