Dunlop SP Winter Sport 4D Review

Dunlop SP Winter Sport 4D is a High Performance Winter tire

High performance winter tires provide a nice blend of crisp handling, high-speed capabilities and snow and ice traction. These tires are branded with mountain/snowflake symbol to meet severe snow service standards. High performance winter tires often come in low profiles and large wheel diameter sizes to fit luxury coupes, sports cars, crossover and sport utility vehicles.

Dunlop SP Winter Sport 4D tire was designed to perform in cold winter temperatures, providing reliable traction on dry, wet, slushy and snow-covered roads. SP Winter Sport 4D tires utilize a motorsport derived silica-plus tread compound that delivers high levels of grip, particularly on wet roads and in low temperatures. This compound is molded into a directional tread design featuring long V-shaped grooves that help resist hydroplaning to maintain good traction on wet and slush-covered roads. 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. The SP Winter Sport 4D tire's structure includes twin steel belts reinforced by Dunlop's JointLess Band (JLB) to optimize the contact patch shape and minimize deformation at high speed. Dunlop SP Winter Sport 4D winter / snow radials meet the industry's severe snow service requirements and are branded with the three-peak mountain snowflake (3PMSF) symbol. Install Dunlop SP Winter Sport 4D tires in sets of four only.
