Continental Tire the Americas’ steer and all-position HSR2 SA (Heavy Steer Regional, Special Application) tire for the recreational vehicle and regional bus segment is designed to maximize fuel efficiency on regional roads through advanced tread design and compounding. The tire – verified in July by the U.S. EPA SmartWay Transport Partnership as a low rolling-resistance truck tire when used in line-haul steer positions – features customized tread geometry that aids in water evacuation for good wet traction while reducing stone retention that can damage the tire’s casing.
A five-rib tread design helps balance pressure distribution, while the company’s proprietary VAI+ visual alignment indicator system helps ensure even wear. The VAI+ system is a series of sipes that helps detect faulty alignment conditions by allowing early detection of wear differences between the shoulder ribs; the feature also indicates tread wear by changing from a plus sign to a minus at 8/32 inches of tread wear, and then disappearing at 4/32nds. The HSR2 SA is available in sizes 275/80R22.5, 295/80R22.5 and 315/80R22.5.
