The Dunlop SP Winter Sport 4D ROF is a run flat winter tire manufactured for passenger tires. The tire offers excellent winter weather traction and great hydroplaning resistance by eliminating water from below the tire footprint. The model is capable of supporting the vehicle for 50 miles up to 50 mph after the loss of air pressure due to a puncture or damage. The 4D siping design stiffens the tread blocks, which improves the steering responsiveness and driving stability. The same siping detail increases the braking and accelerating ability. The SP Winter Sport 4D ROF offers a road vibration-free drive.
The 4D siping system and the silica-plus tread compound improve the winter weather traction and road gripping ability.
The V-shaped grooves and the deep snow notches enhance the hydroplaning resistance by dispersing water from the footprint.
The 4D siping system’s self-interlocking sipes enhance the tread block stiffness and boost the driving steering and stability.
Run Flat Tire
The model supports the vehicle for a limited temporary time after the loss of air pressure thanks to the reinforced sidewalls.
The 4D sipe system increases the number of the shoulder sipes which shortens the braking distance and improves acceleration.
The road vibrations felt in the vehicle’s cabin are reduced with the Jointless Band Technology and the twin steel belts.
