The Dunlop SP Winter Sport 4D is a high-performance winter tyre, designed to provide exceptional grip, handling, and braking ability in all winter driving conditions. Its unique tread design features the latest developments in Dunlop's 4D Sipe system, which provides enhanced snow and ice traction, control, and grip in wet conditions.
- The tyre's new "V" shape grooves and Deep Snow Notches ensure excellent performance on snow, while its tread compound with functionalised polymers delivers exceptional Wet and Ice performance. The directional tread design forces water between the groves, reducing the risk of aquaplaning.
- The SP Winter Sport 4D offers a range of benefits to drivers, including better cornering in both wet and dry conditions, excellent grip on snow, very good wear resistance, and enhanced snow and ice traction. Its unique tread design puts a high number of biting edges in contact with the road, giving you enhanced traction on snow and ice.
- The tyre's low weight construction provides lower rolling resistance, leading to improved fuel consumption and reduced CO2 emissions from your journeys. The Specific Bead Seat System strengthens the link between tyre and rim for a more precise driving experience, enhancing control and conveying outstanding road feedback.
- Other features include the Silica-Plus Compound, which delivers high levels of grip, particularly on wet roads and in low temperatures. The Jointless Belt (JLB) reduces circumferential deformations at high speeds, providing superior high-speed stability. The Maximum Flange Shield (MFS) protects expensive alloy wheels from kerbing.
- The 4D Sipe system sees the tread separated into blocks that increase friction and stability during cornering, delivering superb lateral grip in snow. The Variable land to sea ratio delivers high levels of aquaplaning resistance, with a massive outer shoulder block ensuring rapid and turbulence-free water drainage.
- The flatter tread profile features a 4-8% bigger contact patch, depending on size and type of tyre, delivering more stability and enhanced road feedback. The Multi Blade System meets the challenge of varying winter road conditions, while Functional Polymers produce enhanced performance characteristics at low temperatures.
- Finally, the Multi Radius Tread (MRT) designs employ ten different radii, providing highly effective pressure deployment on the road contact patch, resulting in smoother transitions from straight to corner and more precise and progressive reactions.
