Dunlop SP Winter Sport 4D Performance Winter / Snow tires were developed for sports cars, coupes and sedans that come from the factory equipped with low profile tires mounted on large diameter alloy wheels. Designed to perform in cold winter temperatures, SP Winter Sport 4D tires provide 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.
Do not mix radial winter / snow tires with tires of other construction, size, ply rating or pattern type. Dunlop highly recommends fitment of four winter / snow tires of the same type and rating for optimum mud and snow traction as well as to maintain vehicle handling characteristics.
