Double Coin RT600 8.00R19.5 124/122M FOVERVIEWDesigned for pickup and delivery and regional applications, the Double Coin RT600 is an all-position steer tire that comes with a 5-rib tread design and wide shoulders for enhanced durability, even wear, and solid handling. While the reinforced casing allows multiple retreads, the protective sidewall of the RT600 resists curb, cuts, and abrasions to guard the tire against damage. Boasting EPA SmartWay-verified technology for improved fuel mileage, the RT600 features longitudinal grooves and sipes that help flush water quickly from the surface while regaining traction at the same time.
