Brand new asymmetric passenger car tyre from Federal, featuring great performance, combined with unprecedentedetly low noise and good level of wet grip. AZ01 is a result of extensive research and testing of new tire engineering solutions, compounds and pattern designs, aimed at achieving best possible combination of performance, comfort, security and efficiency.
Outside: Pattern with well-balanced rigidity makes pressure on contact patch spread equally, providing excellent dry surface handling.
Inside: Curved groove walls are designed to aide shoulder water-directing grooves in water evacuation, providing stability and safety on wet roads at high speeds. Central part of pattern is designed to increase resistance to hydroplaning.
Brand new noise-reduction design: 5 differently formed blocks are placed in optimized disorder fashion to reach lowest noise level. New wide outer profile design, while turning, not only allows to spread car weight pressure on contact patch more evenly, but also expands contact patch surface, improving handling.
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.
