Abstract: A bond of a rubbery component to a virgin surface of a tire's cured innerliner which virgin surface has never been contaminated by the remnants of a release agent left after buffing with a wire brush and solvent-cleaning the cured innerliner, is unexpectedly stronger than a bond of the component to the contaminated but “cleaned surface”, cleaned as indicated.
