The Goodyears I’ve had on 8 Dodge/ RAM trucks have all worn out around 20,000 miles.Driving style, proper alignment, proper pressure, and rotating them, are huge factors. My dad got 80,000 out of a set of Michelins. The worst are Goodyears, they use soft rubber for handling, and wear extremely fast. I had a set of Eagle G/Ts worn before 25,000 miles. When I was complaining at the tire store, about how fast they wore, the tire guy said most cars they were replacing those on, were less than 20,000.
