The RoadX RH648 Regional All Position is optimized for steer axles. The RH648 features a broad 5 rib tread pattern to provide precise handling and excellent stability. Wide circumferential grooves efficiently evacuate water from the tread area and feature “stone ejectors” to prevent stone drilling for a long casing life and improved retreadability. The RH648 is ideally suited for regional line haul applications, pick-up and delivery and highway service. SmartWay verified tires can improve fuel efficiency by 3 percent or more.
