EU Tyre Label and Efficiency Classes

The European Union has introduced the EU Tyre Label by Regulation (No. 1222/2009) identically and bindingly for all EU member states. It applies to passenger car tyres, light commercial vehicle tyres and heavy commercial vehicle tyres produced after 01.07.2012.

Three different areas are tested: rolling resistance, wet grip and the rolling noise the tyre makes on the road.

The following are not affected by the EU Tyre Label: retreaded tyres, professional off-road tyres, racing tyres, tyres with additional devices to improve traction such as spiked tyres, T-type emergency tyres, special tyres for fitting to vehicles first registered before 1 October 1990, tyres with a maximum authorised speed of 80 km/h, tyres for rims with a nominal diameter of 254 mm or less or 635 mm or more.

With this regulation, the European Union is pursuing the goal of promoting economic and ecological efficiency in road traffic as well as increasing road safety on the one hand, and on the other hand, granting consumers more product transparency and at the same time serving as an active decision-making aid.

Already during the incorporation, experts criticise the fact that the EU Tyre Label unfortunately only shows a few product characteristics. Apart from rolling resistance, wet grip and rolling noise, which are the main focus of EU tyre labelling, tyres have much more important and safety-relevant product characteristics, such as aquaplaning properties, driving stability, service life, braking properties on dry and wet roads, behaviour in wintry conditions, etc.

Tyre manufacturers point out that test results from various institutions and journals remain an important information medium for the end consumer. These tests usually focus on further safety-relevant product characteristics besides the EU standard qualifications for tyre labelling, which are always important for the final customer.

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

Excellent quality well priced tyre. Arguably grips better than both Pirelli and Marangoie tyres that I've had on my Fiesta. Highly recommended.

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.

They dont have any traction and they are very noisy
