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.
Closed Shoulder Design The closed shoulder design of the tire effectively reduces road noise, ensuring a quieter ride for drivers and passengers. At the same time, this design maintains excellent handling and cornering performance, providing stability and responsiveness even during sharp turns or sudden maneuvers.
Four Main Groove Design Featuring four wide circumferential grooves, the tire significantly reduces the risk of hydroplaning by efficiently channeling water away from the contact patch. This design enhances wet traction, improving grip and safety on rain-soaked roads.
Optimized Depth for Lateral Grooves and Sipes The tire incorporates a carefully engineered depth for both lateral grooves and sipes, ensuring optimal stiffness across all tread blocks. This balanced stiffness not only improves tread wear uniformity but also extends the overall mileage of the tire, allowing for longer-lasting performance.
Optimized Variable Pitch Tread Pattern Utilizing computer simulations, the tread pattern features an optimized variable pitch arrangement. This advanced design minimizes noise generated by the tread blocks contacting the road surface, resulting in a quieter and more comfortable driving experience for occupants.
Silica-Infused Tread Compound The new silica-infused tread compound enhances grip on wet and slippery surfaces, providing superior traction in challenging conditions. Additionally, the silica formulation reduces rolling resistance, contributing to improved fuel efficiency and a safer, more economical drive1.
The Tire Labeling Ordinance specifies the information requirements on fuel efficiency, wet grip and external rolling noise from tires. In addition, reference is made to the winter properties of the product.
The EU 1222/2009 regulation that has been in force since November 1st, 2012 has been revised and will be replaced by regulation EU 2020/740 from May 1st, 2021; From this point on, new requirements apply. The rating classes for fuel efficiency, wet grip and exterior noise have been changed and the layout of the EU label has been adjusted. The manufacturer's product data sheets stored in the EU database can be downloaded via a QR code integrated into the label. Information on snow grip and ice grip is also newly included for tires that meet these criteria.
The following tires are exempt from the regulation: - tires that are designed exclusively for installation on vehicles that were first registered before October 1, 1990 - retreaded tires (until a corresponding extension of EU VO 2020/740 has taken place) - professional off - Road tires - Racing tires - Tires with additional devices to improve traction, eg studded tires - T-type emergency tires - Tires with a permissible speed below 80 km/h - Tires for rims with a nominal diameter ≤ 254 mm or ≥ 635 mm
The criteria and evaluation classes at a glance
fuel efficiency
The fuel consumption depends on the rolling resistance of the tyres, the vehicle itself, the driving conditions and the driving style of the driver. The measured rolling resistance (rolling resistance coefficient) of the tire is divided into classes A (highest efficiency) to E (lowest efficiency).
If a vehicle is completely equipped with class A tires, a consumption reduction of up to 7.5%* is possible compared to class E tyres. In the case of commercial vehicles, it can even be higher. (Source: European Commission Impact Assessment * when measured according to the test methods set out in Regulation (EU) 2020/740)
Please note: Fuel consumption depends to a large extent on your own driving style and can be significantly reduced by driving in an environmentally friendly manner. Tire pressure should be checked regularly to improve fuel efficiency.
wet grip
Wet grip is divided into classes A (shortest braking distance) - E (longest braking distance).
If a car is equipped with class A tires, compared to class E tires, a braking distance of up to 18 m can be reduced when braking from 80 km/h (on a road surface with average grip).* *Source: wdk Economic Association of the German Rubber Industry eV
Please note: Traffic safety depends to a large extent on your own driving style. The stopping distances must always be observed. Tire pressure should be checked regularly to improve wet grip.
External rolling noise
The noise emitted by a tire affects the overall volume of the vehicle and affects not only your own driving comfort, but also the noise pollution of the environment. In the EU tire label, the external rolling noise is divided into 3 classes from A (lowest rolling noise) - C (highest rolling noise), measured in decibels (dB) and compared with the European noise emission limit values for external tire rolling noise.
A The pictogram with the classification "A" indicates that the tire's external rolling noise is more than 3 dB below the EU limit value in force until 2016. B The "B" classification means that the tyre's external rolling noise is up to 3 dB below or equal to the EU limit value in force until 2016. C The classification "C" indicates that the specified limit value is exceeded.
