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 has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.
Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.
The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.
With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.
Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.
Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.
