Depending on the application the outer circumference of the rim may have a flange machined into it so that it serves as the tire for the wheel or machined smooth to accept a separate tire.

The rim is thus effectively prevented from shifting even if the adhesive substantially or even totally disbonds from the mated parts. Several variants of these locking pins are possible to achieve improved economy for maintenance purposes or improved longevity of the wheel.
