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.

21.09.2019fromA Sam I used these on my drift/track car, and yes I know many won't see the point, but having had many years experience in instructing on track, track etiquette, super cars experience and drifting techniques and coaching. I am aware of the difference between road tyres, track biased and racing slicks. These by no means are either of the latter but ultimately if you prefer the predictability of a road tyre and good overall performance then I'd recommend these. Good dry/wet grip and reasonable wear. I would say these would be better on a lighter car. My E36 328 sport is fully stripped with a cage, it handles and out performs my E46 M3 I owned and tracked for 8 years. Having come across many E46 M3s & many other performance cars on track cornering ability was strong, keeping up and overtaking many of those cars (I also did get overtaken by a few, buty ego is check and I'm no issue with that) with these tyres on UK tracks and at Spa Francorchamps / Nurburgring this year (2019). They will heat up and you will find the limits of these, so if you like abusing your car on track lap after lap for 10+ laps in 30*C temps without a break, then get slicks or track comps but if you have some mechanical sympathy then I'd recommend these Sunny's.
Overall a good option for the road and possibly track/drift if you have a lighter car. And don't mind a softer sidewall.
I will be buying these again and hope this info helps someone.
Thanks
17.10.2014fromAllan Smith Excellent quality well priced tyre. Arguably grips better than both Pirelli and Marangoie tyres that I've had on my Fiesta. Highly recommended.
26.03.2014fromTim Excellent budget tyre. Grip not noticeably different from Perelli P zeros, Continential Contactsport2 that I have used before and I usually drive with traction control off to feel what grip I have. I've had to lower the pressure on the rears as they were wearing in the centre. But I have had this with other makes. 10,000miles on the rears, tread down from 8mm to 4.3mm in the centre 6mm on the edge.
29.09.2013fromMiguel They dont have any traction and they are very noisy
