The winter RW06 uses silica compounds which are helpful in providing stability on now only snow and icy roads but slushy surfaces. Cutting-edge tie-bars stabilise alignment on snowy and icy roads by maximising handling performance.
Straight and 2 semi zigzag grooves Based on 3 main grooves to secure safety on wet roads, the tyre is designed to satisfy both hydroplaning and snow performance by accepting the straight centre and 2 surrounding zigzag grooves.
Employing the new profile tie-bar The tie-bar along the wall of blocks in the shoulder helps to secure dry handling and ice and snow traction competence. Adding kerfs in the shoulder tie-bar means snow performance is not reduced even after the mid-term abraison.
Cross block system By crossing and linking thread blocks, alignment safety and braking performance on the icy roads are secured.
Cliff grooves Cliff groove maximises the snow edge effect on the groove wall.
Wide, high-tensile steel belts Enhanced tread strength for faster steering response and longer life.
Max-strength bead construction Maximum steering response, high-speed stability and durability.
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.
