Confident handling, all year around. Year-round performance, strong grip on winter roads, high aquaplaning resistance plus smooth and stable at high speeds. The Dunlop SP 4All Seasons delivers stability and control all year around.
Year round performance. The SP 4 All Seasons gives you the performance to deal with changing road conditions throughout the year. Its dual-silica tread compound performs well across a broad range of temperatures, from summer heat to winter freezes.
Strong grip on winter roads. Tackle winter roads with confidence. The tread pattern creates an interlocking effect that ensures good traction on snow, ice and slush. The SP 4 All Seasons is certified with the snowflake symbol for winter use.
High aquaplaning resistance. Navigate wet and thawing roads with a reduced risk of aquaplaning. A directional design with wide grooves allows for rapid evacuation of water from the tyre contact patch.
Smooth and stable at high speeds. The tyre keeps its shape at high speeds, giving you a smooth ride and a tyre that wears evenly.
Specific bead seat system. Strengthens the link between tyre and rim for a more precise driving experience. Like the grip between your hand and the steering wheel, the Specific Bead Seat System enhances control and conveys outstanding road feedback. Benefits Enhanced road feedback; greater stability and precision.
Directional Tread Design. Designed for those cold wet morning drives, the directional tread design forces the water between the grooves. Water is quickly channeled away from the tyre surface, reducing the risk of aquaplaning.Benefits Reduced risk of aquaplaning.
Silica-Plus Compound. A motorsport derived tread compound that delivers high levels of grip, particularly on wet roads and in low temperatures.Benefits Superb braking and acceleration performance; high grip in wet and cold-weather conditions; low wear and tear. Jointless Belt (JLB) A Hybrid Overlay Technology that reduces circumferential deformations at high speeds.Benefits Superior high speed stability
Maximum Flange Shield (MFS). A rim flange protection system. MFS employs a profile of rubber that runs around the circumference of the tyre above the wheel flange. This creates a protective buffer zone.* Benefits Protects expensive alloy wheels from kerbing.* Only available in select sizes
4D Sipe System. The 4D Sipe system sees the tread separated into a number of blocks that increase friction and stability during cornering. The system delivers superb lateral grip in snow.Benefits Superb cornering, even in snow.
V-Shape Grooves. ‘V’ shaped grooves in conjunction with the tread’s basic grooves create a fine network, which collects snow in the tread. This snow-on-snow contact enhances traction and grip.Benefits Advanced snow handling.
Flatter tread profile. The new generation of Dunlop tyres features a flatter tread profile with a 4-8% bigger contact patch, depending on size and type of tyre. A bigger contact patch delivers more stability and enhanced road feedback, allowing tires to respond quickly and precisely.Benefits Increased stability and steering precision; reduced heel and toe wear; excellent cornering stability and precision; superior dry grip.
Multi Blade System. Winter driving conditions can vary greatly. From cold and dry to snow or sleet, these conditions make very high demands on a tyre. Dunlop’s multiple blade system meets this challenge head on, with different types of blades for varying winter road conditions.Benefits Consistent performance in various winter conditions.
Functional Polymers. Functional Polymers in the tread compound produce enhanced performance characteristics at low temperatures, improving road adhesion when winter temperatures plummet.Benefits Exceptional grip at low temperatures.
Multi Radius Tread (MRT). MRT designs employ ten different radii and are therefore more precise. This results in highly effective pressure deployment on the road contact patch. The effect is smoother transitions from straight to corner, leading to more precise and progressive reactions.Benefits Significantly better control over the evolution of the footprint in all driving conditions; responsive wet and dry handling; increased cornering control.
EU Tyre Label and Efficiency Classes
The European Union, under CE 1222/2009, has mandated that all tyres manufactured after the date of July 1 2012 for cars and commercial vehicles include standard EU Tyre Labels classifying them by three performance characteristics:fuel efficiency classified from A to G,wet grip classified from A to G, and noise emission in decibels.
Categories of tyres unaffected by this regulation include: retreaded tyres, professional off-road tyres, racing/sports car tyres, as well as certain types of tyres designed to improve traction such as studded tyres, T-type temporary spare tyres, tyres for cars built before 1990, tyres with a maximum allowed speed of 80km/h, tyres for rims with a diameter less or equal to 254 mm or greater or equal to 635 mm. This label is intended on one hand to promote economic and ecological efficiency in traffic, as well as increase road safety, and on the other hand to help consumers select appropriate tyres by ensuring a certain degree of product transparency.
Nevertheless, the label has been criticized for only showing a very limited number of characteristics. Professionals argue that tyres have many more features that are important and relevant to road safety, including but not limited to aquaplaning properties, driving stability, service life, product properties on wet and dry roads other than wet grip, properties on snow. Tyre manufacturers suggest that the test results from various institutions and industry magazines should remain a very important source of information for the end consumer, because they focus on and rate a wide variety of tyre properties and features.
