The Dunlop Winter Sport 3D DSST (Dunlop Self-Supporting Technology) tires are designed for coupes, sedans and even sports card that has factory equipped low profile tires installed on large diameter alloy wheels. These are self-supporting run-flat performance winter tires. This features a design that enables driving even when the tire is punctured allowing complete pressure loss and is also great for use in cold winter conditions. This tire also boasts traction on wet, slushy, dry and even on snowy driving conditions.
The Dunlop Winter Sport 3D DSST uses Dunlop’s reactive silica mixing process making its tread compound more elastic at low temperatures giving greater grip in winter road conditions. This is shaped into a directional tread design with long v-shaped grooves that makes it resistant to hydroplaning – perfect for great grip on wet and slushy roads.
The 3 different types of high density sipes gives 3 distinct traction zones in one tire. The central tread block has “pulling”sipes to give grip while speeding and braking especially on snow and ice. The intermediate blocks has high-amplitude sipes to improve safety and control in slushy or wet roads. Lastly, the 3D sipes in the shoulder blocks interlock to maximize stability on dry road but still maintaining needed traction when on ice or snow.
This tire also features twin steel belts with Dunlop’s JointLess Band (JLB) of nylon to maximize the contact patch and lessen tire growth even at high speeds. This also has sidewall reinforcements that can temporarily support the vehicle’s weight even after losing air pressure that can make other tires not usable. This enables users to drive on deflating tire up to 50 miles with speed up to 55 mph making it safer to driver away from stormy weather and danger.
