A non-pneumatic tire includes an annular inner ring, an annular outer ring, and a support structure positioned between the annular inner ring to the annular outer ring. The support structure includes a multilayer structure of a rubber skim layer and a cord embedded in the rubber skim layer. The rubber skim layer has resistance to ozone exposure without need for a protective layer overlying the rubber skim layer. The rubber skim layer exhibits adhesion to embedded metallic cords. Methods of making a non-pneumatic tire include forming a multilayer structure by applying a skin layer directly over one or more cords.
