The Bridgestone A005 Weather Control Evo all-season tyre is designed for passenger cars with enhanced dynamic properties. It is the latest edition to Bridgestone's all-season tyre range that offers outstanding wet grip and enhanced snow performance. It was introduced in 2018 and quickly gained widespread popularity around the world.
It is characterized by:
Best-in-class Wet Grip Index
Sporty handling on dry surfaces
Enhanced snowy and slippery roads performance
Superior wear life
The tread of the tyre is made from a Nano Pro-Tech rubber compound, distinguished by its high content of silicon oxides and special polymers. This composition ensures the tyre remains highly grippy on cold, wet asphalt and is resistant to abrasive wear, even with dynamic driving.
Computer modeling was extensively used in the tyre's development, particularly for the carcass. The optimized design significantly improves the uniformity of pressure distribution across the contact patch, which, in turn, enhances maneuverability and greatly reduces uneven tread wear.
The directional V-shaped tread design plays a crucial role. The central part of the tread features a large number of small elements arranged at an angle to each other. Four deep longitudinal drainage channels encircle the tyre. In conjunction with the small transverse grooves, these channels quickly evacuate water, slush, or liquid mud from the contact patch, improving traction and preventing aquaplaning.
EU Tyre Label and Efficiency Classes
The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.
Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.
The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.
With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.
Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.
Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.
