The efficiency class label evaluated based on customer preferences. Delticom centralized survey results from more than 40.000 customers from 15 European countries and created this index.
Wide Outer Tread Blocks with Narrow Longitudinal Grooves The outer section of the tire features large tread blocks paired with narrow longitudinal grooves. This design enhances cornering grip by increasing the tire’s contact with the road during turns, ensuring precise handling and stable vehicle control even in demanding driving situations.
Multiple Longitudinal Main Groove Design The tread incorporates several main longitudinal grooves, which efficiently channel water away from the contact area. This reduces the risk of hydroplaning and significantly improves wet traction, providing drivers with greater confidence and safety on rain-soaked roads.
Streamlined Inner Diagonal Groove Design On the inner side, the streamlined diagonal grooves are engineered to further boost water evacuation. This not only enhances the tire’s drainage performance but also increases grip on wet surfaces, contributing to safer driving in adverse weather conditions.
Optimized Variable Pitch Arrangement Using advanced computer simulations, the tread pattern’s pitch sequence has been meticulously optimized. This variable pitch design minimizes noise generated by tread block impact with the road, resulting in a quieter and more comfortable ride—an aspect especially valued by those interested in noise reduction and tire performance1.
Silica-Infused Tread Compound The innovative silica-based tread compound delivers superior grip on wet and slippery roads while also reducing rolling resistance. This combination ensures safer driving and improved fuel efficiency, making every journey both secure and economical.
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.
