The tread design, compound and casing structure all boast specific features for use in low temperatures. In confronting this significant challenge, Pirelli was encouraged by the excellent results achieved with the most recent Winter tyres, and triumphed thanks to the technology and experience gained through participation in motorsport. The Winter SOTTOZERO design sets new performance standards for Winter tyres enhancing safety and driving pleasure. Deep diagonal grooves, a distinguishing feature of the Sottozero tread pattern that reduce road noise and, assisted by the specially designed blocks, enhance the acoustic comfort and rolling resistance qualities. Broad, deep longitudinal grooves with differentiated profiles allow water to be expelled, even at high speed, thus raising the aquaplaning threshold. Substantial shoulder blocks confer exceptional lateral rigidity to the tread when under load during cornering, raising the limits of grip and ensuring precise handling through sudden changes in direction.
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.
