Vredestein Wintrac Xtreme S
Vredestein’s Ultra High Performance winter tyre, the Wintrac xtreme S, was developed to stand up to the extreme weather conditions in the coldest season of the year. Maximum safety on snow and ice are as important as grip and steering precision for the Wintrac xtreme S, especially on the cold snow-free surfaces on which people drive the majority of the time.
Thanks to its Internal Sipe Locking Technology (ISLT), the Wintrac xtreme S takes the characteristics of a top-class winter tyre to a whole new level. The technology minimises deformation of the sipes in the tread, resulting in excellent course stability, greater steering precision and an enhanced sense of safety at higher speeds. There are many sizes available with the Y speed index and - combined with the great looks that come from a Giugiaro-designed tyre - this makes the Wintrac xtreme S suitable for the highest performance and most exclusive cars.

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.
