The Goodyear Tire & Rubber Company revised earnings guidance for the year 2018. The Company will announce that fourth quarter of 2018 tire unit volumes declined by approximately 3% due to continued weakening of the OE environment in China and India, declines in the winter tire market in Europe late in the quarter, and supply constraints on volume for high-value-added consumer and commercial truck tires in the United States. As a result of these factors, for the full year of 2018, the company expects net income is expected to be adversely affected and the company's total segment operating income is expected to be slightly below the company's previous guidance of approximately $1.3 billion.
