The Dynapro HP2 RA33 is molded from a high-silica tread compound that provides excellent all-season traction, lowers rolling resistance for reduced fuel consumption, and improved noise levels for increased ride comfort. The tread design features a sloid center rib for precise steering as well as straight driving stability, and 4 wide circumferential grooves for removing water from the contact patch to reduce risk of aquaplaning. Longitudinal sipes in the outer tread provide additional biting edge for better traction in snow. The 3D tread block design combined with radial direction sipes interlock for increased block stiffness and improved handling on dry roads. The internal structure of the tire comprises nylon-wrapped, jointless twin steel belts, robust strand bead wire and high-density polyester carcass for responsive steering and improved handling, on both wet and dry roads.
