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.
The V-groove and streamlined pattern design supplemental with two wide longitudinal grooves for drainage and rim protector on the sidewall can provide superior high speed stability in straight driving and excellent handling performance.
Adoption of silicon dioxide technology substituted for the traditional carbon black can reduce the rolling resistance, increase the traction and shorten braking distance to ensure the safety of driving.
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.
The brand Goodride stands for high quality in the lower price range
and offers an excellent price-performance ratio.
The manufacturer is the Zhongce Rubber Group Co., Ltd. (ZC Rubber for
short) founded in 1958, based in Hangzhou, the capital of East China’s Zhejiang province.
The company is the largest tyre producer in China and has grown in recent
years to become one of the ten leading global tyre manufacturers, alongside brands such as Michelin,
Continental and Bridgestone. The declared aim is to further expand their position and to increase their share
of the tyre market. In order to do this, the firm invests in new production facilities, representative bodies and
cooperations worldwide.
Different brands are produced in numerous plants in China and in Thailand.
Tyres for cars, transportation vehicles and trucks, for agricultural, construction and commercial vehicles as
well as for motorcycles and bicycles feature in ZC Rubber’s range. In addition, rubber tracks for caterpillar
vehicles as well as tubes are made.
When it comes to production and production control, modern equipment from
reputable manufacturers is used, and quality management is oriented around the requirements and
standards of the international tyre market.
For measuring and optimising tyre noise emission, ZC Rubber established the
first anechoic laboratory rooms in China. Furthermore, the company goes to great lengths with concerns
such as gas recovery, steam cleaning, water purification and waste treatment for the sake of
environmentally friendly production.
