Patent ID: 8336591

Claim:
A method of making a pneumatic tire, comprising the steps of: adding carboxymethylcellulose to water in a concentration ranging from 1 g of carboxymethylcellulose per 10 g of water to 1 g of carboxymethylcellulose per 1000 g of water to make an aqueous solution of carboxymethylcellulose; mixing the aqueous solution of carboxymethylcellulose with a latex of the at least one diene based elastomer to make a first mixture; coagulating the first mixture using a one percent solution of calcium chloride; washing of the coagulated solids with water; drying the coagulated solids to make a composite of carboxymethylcellulose and elastomer, mixing the composite of carboxymethylcellulose with at least one of silica and carbon black to make a rubber composition comprising a reinforcing amount of at least two fillers, the two fillers comprising the carboxymethylcellulose and the at least one of silica and carbon black; and fabricating a tire comprising at least one component, the at least one component comprising the rubber composition.
