Dunlop's newest Performance Winter / Snow tire, the SP Winter Sport 4D, is now available for the upcoming winter season. Like the tire it replaces, the SP Winter Sport 3D, the new SP Winter Sport 4D features a directional pattern that has proven to be excellent at evacuating slush and snow. It also retains its high speed rating (V for most sizes) and looks to be a continued acceptable performer on dry and plowed roads.
Drivers will see only small changes when compared to the older model, with the largest improvement coming in the form on brick styled sipes. Over the past winter season, the Dunlop SP Winter Sport 3D made a name for itself as the highest rated tire in its class.
The tire utilizes a motorsport derived silica-plus tread compound that delivers high levels of grip, particularly on wet roads and in low temperatures. Dunlop's 4D Sipe System combines their 3D sipe technology with transverse sipes to create independent micro-blocks that generate better footprint pressure distribution to enhance snow handling and cornering grip.
