The Dynapro HT (RH12) is Hankook's premium Highway All-Season tire developed for the drivers of vans, pickups and sport utility vehicles. Dynapro HT tires are designed to combine long treadwear, good ride comfort and all-season traction, even in light snow.Dynapro HT tires feature a computer generated symmetric tread design that promotes even wear, low noise and all-season traction. Stable shoulders aid steering response while lateral notches increase traction in wet and wintry conditions. Independent intermediate tread blocks feature an interlocking geometry that allows them to generate traction in rain and snow while preserving block stability for handling. A high-stiffness continuous center rib enhances steering response and straight-line tracking. Four circumferential grooves help channel water to resist hydroplaning and help maintain wet traction, while zigzag sipes located across the tread design increase the number of biting edges to improve wintertime traction.
