This invention relates to a heavy duty tire (e.g. heavy duty truck tire) intended for significant load bearing capacity with a rubber tread of cap/base construction. The outer tread cap rubber layer is intended to be ground-contacting and the tread base rubber layer underlies the outer tread cap rubber layer to thereby provide an interface between the between the tread cap rubber layer and tire carcass. The elastomer of at least one of said tread cap rubber and tread base rubber layers layer is comprised of greater than 50 weight percent natural cis 1,4-polyisoprene rubber. The reinforcing filler for at least one of tread cap and tread base rubber layer contains oxidized rubber reinforcing carbon black.
