A support ring for a tire is disclosed. The support ring is to be mounted on a tire wheel for support of the underside of the tire when the tire is operated at underinflated conditions. The outer surface of the support ring is provided with a set of grooves that permit lubrication to freely travel over the surface of the ring during use.
