AKRON, Ohio (AP) — Goodyear is testing tires made with soybean oil as it tries to cut its use of petroleum and extend tread life.

The Akron, Ohio, company said Tuesday that its researchers have found that the tread on tires made partially with soybean oil can last 10 percent longer than current tires. The soybean oil, which comes from a renewable resource, could cut Goodyear’s use of petroleum by up to 7 million gallons per year, the company said in a statement.
