The Dynapro AT2 (RF11) is Hankook's On-/Off-Road All-Terrain tire developed for drivers of pickup trucks, Jeeps, work vans and full-size SUVs who are looking for a satisfying blend of all-around performance. Designed to provide durability and versatility in varying surface conditions, the Dynapro AT2 combines off-road prowess, dry and wet traction, and the confident light snow traction that comes from being marked with the three-peak mountain snowflake (3PMSF) symbol.The tread compound of the Dynapro AT2 was specifically formulated to improve fuel economy and provide cut- and chip-resistance on rough surfaces. Rigid tie bars in the shoulders help stabilize the tread blocks for improved ride comfort and dry handling, and the stepped block edges reduce airborne noise emanating from the symmetric tread pattern. High-dispersible silica in the tread compound enhances grip in wet conditions, and the open shoulders and wide grooves help evacuate water from the contact patch to resist hydroplaning. Multi-directional grooves and sipes are arranged to find traction in any direction, while the independent tread blocks feature extra biting edges for grip off-road and in snow.A durable, three-ply casing helps resist punctures and damage during off-road use. The wide footprint is computer modeled for more even distribution of pressure, aiding tread life and even wear. Two high-strength, steel belts are reinforced with two nylon cap plies to further aid durability and high-speed capability.Note: While non-winter tires featuring the three-peak mountain snowflake (3PMSF) symbol provide additional longitudinal snow traction beyond what all-season (M+S) tires not bearing the symbol can deliver, they do not match the capability of a true winter tire in all adverse weather conditions.
