Abstract
A tire component comprising a rubber composition having a highly unsaturated diene elastomer and a reinforcing filler with a first methylene acceptor selected from 3-hydroxydiphenylamine, 4-hydroxydiphenylamine or combinations thereof; a second methylene acceptor selected from a Novolac resin, diphenylolmethane, diphenylolethane diphenylolpropane, diphenylolbutane, a naphthol, a cresol or combinations thereof and a methylene donor. A method for manufacturing a tire component includes mixing together components of a rubber composition into a non-productive mix, the components including a highly unsaturated diene elastomer, a reinforcing filler, a first methylene acceptor selected from 3-hydroxydiphenylamine, 4-hydroxydiphenylamine or combinations thereof and a second methylene acceptor selected from a Novolac resin, diphenylolmethane, diphenylolethane diphenylolpropane, diphenylolbutane, a naphthol, a cresol or combinations thereof; and mixing a methylene donor and a vulcanizing agent into the non-productive mix to convert the non-productive mix to a productive mix.
