In addition, a method of making a rubber composition includes combining a polar solvent, a base, and a carboxylic acid and mixing these to form a Solution A. A source of metal ions in solution is added to Solution A, whereby mixing forms Product A. The metal in the source of metal ions is selected from the group consisting of metals with an oxidation state of +3 or +4. The product is isolated from Solution A and then is combined with a diene rubber composition to form a useful article, such as the tread of a tire.
