ABSTRACT:
Improved blow-molded wheels, methods for producing the same, and children's ride-on vehicles including the same are disclosed. The blow-molded wheels may include a blow-molded wheel body that is configured to rotate about an axis and has a tread surface that extends circumferentially around the wheel body and may have a circumferential profile that is defined as the locus of points at which the radial distance from the axis to the tread surface is greatest at each position around the circumference of the tread surface. The radial distance from the axis to the circumferential profile may change from a first radius to a second radius that is larger than the first radius at a plurality of spaced-apart positions along the circumferential profile. The method for producing the blow-molded wheels may include providing a mold with pinch-off rings that have an opening configured to form the circumferential profile.
