Further described are methods for making alkoxy-modified silsesquioxanes, methods for making vulcanizable rubber compounds containing alkoxy-modified silsesquioxanes, vulcanizable rubber compounds containing alkoxy-modified silsesquioxanes, and pneumatic tires comprising a component that contains alkoxy-modified silsesquioxanes.
