The Goodyear Tire & Rubber Company today revised its earnings outlook for the second half of 2000, based on continued deterioration of global economic and industry-wide conditions. The company, which had expected limited improvement over the first half of 2000, cited escalating raw material and energy costs, the continued deterioration of the euro's value versus the U.S. dollar, weak pricing conditions in markets around the world and lower-than-expected tire industry volumes in North America and Europe.
