The void ratio of the inside and outside are respectively 38% and 34%, and it can improve tire’s drainage efficiency and also wet handling.

With broadened circumferential groove width, the section area of inside/ outside grooves are increased 21.3% and 43.8% respectively compared to the conventional design. And it can increase the volume to contain more water for better drainage performance.

Brand new profile design and reinforced sidewall design can upgrade tire stiffness.

Serrated wall of circumferential groove: Discharge water in the circumferential grooves promptly and effectively, as well as reduce the noise caused by the friction between airflow and groove wall.

For inside and outside lateral groove on tread shoulder, we use chamfering design to optimize the angle of lateral grooves, and it can reduce tire’s rolling sound and improve block stiffness effectively.

EU Tyre Label and Efficiency Classes

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).*

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.

As tyres on rear axle they perform very good, never slipped, not noisy, no vibrations, not worn, perfect for the price, for now I am very happy with the purchase but I have not pushed any tyres to extreme, I am using them as normal driver would mixing countryside, highway and city.
