Goodyear Tire & Rubber Co reported a 9 percent drop in quarterly revenue due to lower shipments of replacement tires in Europe, which the company blamed on a milder-than-expected winter. Goodyear, whose brands include Dunlop, Sava and Fulda tires, said its revenue fell to $4.36 billion in the fourth quarter ended Dec. 31 from $4.79 billion a year earlier. Net income available to shareholders rose to $2.13 billion, or $7.68 per share, helped by a one-time benefit, from $228 million, or 84 cents per share, a year earlier. Excluding items, Goodyear earned 59 cents per share.
