Dynamically designed passenger and SUV tyre for maximum grip and ultra high performance. Leading edge tread design coupled with an advanced silica compound for optimum performance and a responsive drive.
Tried and tested performance
The DX640 has outstanding wet grip ratings and low noise scores, regularly beating other performance brands in tyre tests. Optimal water dissipation is achieved through four longitudinal grooves and these are contained within substantial tread blocks for superior noise reduction.
Features and Benefits
The outer block pattern consists of two key elements, the solid rectangular inner blocks provide maximum grip when cornering, whilst the outer tapered deep sipe section provides drainage even as tread decreases throughout the useful life of the tyre.
The three main inner block sections consist of a 3D shaped pattern resulting in adaptable performance that is optimised as tread depth decreases throughout the life of the tyre.
The inner block sections dynamic design has the dual purpose of drainage and noise reduction with the added benefit of a wider circumferencial groove containing reservoirs to provide inner grip throughout corners.
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.
