The technological objectives of the Yokohama are to reduce the cost for kilometer twirled (bigger useful life of band of set of wheels and excellent index of retreading) without sacrificing the other aspects of performance: traction, stability, comfort, and fuel economy. The engineers of the Yokohama develop technologies, to maximize the performance of the tires.Advanced process of rubber mixture
In the process of manufacture of the tires, one of the main stages is the process of rubber mixture. In this phase, the rubber is combined with mixed and pressed carbon and after that. The Yokohama applied an advanced method of mixture the cold that generates a product of superior quality, becoming more robust and increasing the durability and the resistance to the irregular consuming.The length of the molecule of the rubber is long and uniform
• The carbon is distributed uniformly
• Little obstacles of dioxide
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.
