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 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.

11.03.2022fromDavid I have been an Avon fan for nearly 50 years and currently have 4 of their tyres on my SUV. I've just received an MOT advisory warning that the front 2 are perishing, after only 2 years and 6000 miles of normal use (ie no off road use) - see photo. I've submitted a warranty request to the company and will update this review, based on the response I get.
UPDATE - The response I've received from Avon is that I have to return my car to the garage who fitted the tyres, then get them to remove the tyres and send them back to Avon. That means I have to leave my car sitting on the garage forecourt on its rims for as long as it takes Avon to uplift, examine and report on the tyres. If Avon deem the ZX7s to be faulty, they will refund on the basis of how much tread is left compared to new, but if they think the tyres are 'within normal specification', they will return them to the garage, to be refitted. As an alternative, Avon suggest that I simply buy 2 new tyres, before sending my originals back. That way I don't lose the use of my car, but what happens if they decide that they won't honour my warranty claim? I'll then have 2 sets of tyres! And who pays the garage to do all this work?
If ever there was a procedure designed to hamper a consumer making a warranty claim, then this has to be it. No goodwill from Avon, no acceptance of what an accredited long standing garage or a qualified MOT inspector says. Just a robotic insistence to follow a claims procedure that severely inconveniences customers.
All tyres perish eventually, but not usually after only 2 years and 6,000 miles of normal UK use - and not usually in the valley of the tread (which is dangerous, because it's closer to the structural carcas of the tyre). If my situation was a one off, you could just put it down to bad luck, but a quick internet search reveals plenty of other people with Avon tyres failing in exactly the same way.
Bearing in mind that if you buy Avons and they perish like mine, you will be expected to jump through the hoops I have described above to make a warranty claim, the only logical advice I can give is that everyone avoids buying Avon tyres in the first place.
FOOTNOTE - in terms of performance, I thought that the ZX7s were quieter than the Continentals that came with the car, but inferior in every other way, particularly economy. Anyway, what does performance matter, if a tyre perishes after only 2 years and 6,000 miles of use?
22.06.2019fromSpeegles This is the 3rd set of ZX7s on my Rav4. I'm getting 35000km off each set, and they are nothing short of fantastic. My partner also has them in her B class Mercedes, again, excellent
