The Optimo H426 is constructed from an advanced silica tread compound that is molded into a symmetric pattern with independent tread block design that ensures superior braking performance as well as outstanding grip specially on wet surfaces and even in snow. The tread compound also features lower rolling resistance, which aids in reducing fuel consumption and improved tread life. The rib block design in the shoulders and optimized lateral grooves help to minimize road vibration as well as reduce vibrations for a quiet and comfortable ride. The internal structure consists of a high-tensile steel belt with jointless two-ply cap that offers responsive steering, and a combination of jointless bead wire with robust bead filler for increased stability at high speeds.
