Yes, if the bead ring is removable, it points toward the inside on some rear wheels. The ones that split near the center (Firestone RH-5, AKA Widomaker) have approximately equal width sections, inside and out. The easiest way to identify them is a raised lip about 1/4" thick and 2" wide that's visible on the outer dual when it's mounted on the truck. A pic of the outside dual showing the lug nuts and barrel section of the wheel would help.
