A rubber composition which contains substantially hollow, irregularly-shaped particles, and/or fragments thereof derived from a surface-modified carbon black aggregate from the which the carbon black core has been removed. For example, an irregularly-shaped carbon black aggregate may be surface-modified to have interconnecting domains of at least one inorganic material on its surface and the carbon black core removed by an oxidation process leaving an irregularly-shaped, substantially hollow particle and/or fragments thereof of said inorganic materials. An article having a component of such rubber composition is also provided such as, for example, a tire or an industrial product.
