NEW YORK (Standard&Poor's CreditWire) Oct. 27, 1999ùStandard&Poor's today affirmed its 'A-2' commercial paper rating, its single-'A'-minus corporate credit and senior unsecured debt ratings, and its 'A-2' short-term corporate credit rating on Goodyear Tire&Rubber Co. However, the outlook on the company is revised to negative from stable. The rating actions reflect Goodyear's weak financial performance this year, higher-than-expected debt levels, and concerns that continued earnings weakness could delay expected debt reduction. Goodyear is the world's largest tire manufacturer. The company also produces belts and hoses. Goodyear has reported disappointing results for 1999, due to operating issues in its North American tire business and depressed results in Latin America due to continuing weak economic conditions in
