Dunlop SP Winter Sport 3D DSST RunOnFlat Tread Pattern & Technical Specs

The Dunlop SP Winter Sport 3D DSST (Dunlop Self-Supporting Technology) tires are designed for sports cars, coupes, and sedans that are equipped with low-profile tires installed on big diameter alloy rims. If a puncture causes complete pressure loss, SP Winter Sport 3D DSST tires provide momentary extended mobility. By giving traction in the freezing winter conditions, they are made to provide proficiency on dry, wet, and snow-covered roads.

With the help of Dunlop’s reactive silica mixing technique, the SP Winter Sport 3D DSST’s tread compound delivers great flexibility at low temperatures, providing reliable traction in winter driving. This substance is molded into a directional tread pattern that decreases the possibility of hydroplaning and assists in retaining good traction on wet and snowy roads. In a single tire, three various high-density sipe types define three separate traction zones.

To enhance grip when accelerating and braking, — especially on ice and in snow, the center tread blocks have “pulling” sipes. High-amplitude sipes are used in the intermediate blocks to improve lateral stability and control in slushy and wet conditions.

The 3D sipes in the shoulder blocks also interlock to improve handling and stability on dry roads while maintaining the elasticity required to grip snow and ice. To maximize the contact patch and reduce tire growth at high speeds, the SP Winter Sport 3D DSST tire’s structure contains twin steel belts strengthened by Dunlop’s JointLess Band (JLB) of nylon.

Special sidewall reinforcements built into DSST tires allow them to continue to carry the weight of the car even after air pressure drops that would make regular tires ineffective.

The Dunlop SP Winter Sport 3D DSST winter/snow radials are marked with the three-peak mountain snowflake (3PMSF) and meet the industry’s severe snow service criteria.

It is highly recommended to install sets of four Dunlop SP Winter Sport 3D DSST tires.
