EU Tyre Label and Efficiency Classes

EU Tyre Label and Efficiency Classes

The European Union, under CE 1222/2009, has mandated that all tyres manufactured after the date of July 1 2012 for cars and commercial vehicles include standard EU Tyre Labels classifying them by three performance characteristics:fuel efficiency classified from A to G,wet grip classified from A to G, and noise emission in decibels.

Categories of tyres unaffected by this regulation include: retreaded tyres, professional off-road tyres, racing/sports car tyres, as well as certain types of tyres designed to improve traction such as studded tyres, T-type temporary spare tyres, tyres for cars built before 1990, tyres with a maximum allowed speed of 80km/h, tyres for rims with a diameter less or equal to 254 mm or greater or equal to 635 mm.
This label is intended on one hand to promote economic and ecological efficiency in traffic, as well as increase road safety, and on the other hand to help consumers select appropriate tyres by ensuring a certain degree of product transparency.

Nevertheless, the label has been criticized for only showing a very limited number of characteristics. Professionals argue that tyres have many more features that are important and relevant to road safety, including but not limited to aquaplaning properties, driving stability, service life, product properties on wet and dry roads other than wet grip, properties on snow.
Tyre manufacturers suggest that the test results from various institutions and industry magazines should remain a very important source of information for the end consumer, because they focus on and rate a wide variety of tyre properties and features.

Utter rubbish- they are basically like a budget tyre but with a premium name complete waste of money

Especially for this kind o tire very good comfort and noise levels, even on coarse road surfaces (like in Sweden).

Rubbish! Having run various tyres from budget to high performance these come near the bottom of the list. I ran them in non-RFT form on a Golf R32 and they were mediocre at best but they came standard on the BMW so didn't have a choice. They are very hard and crash about quite lot, they tramline something terrible and traction control light comes on over speed bumps (<10 mph) and on hard cornering - all in the dry! Now, in the wet they are almost lethal. No grip in the corners, wheels spin when pulling off the lights even if you slip the clutch. You only have to visit a few BMW forums or other tyre review sites to read that these comments / concerns are common across the range of BMWs. Avoid these tyres.... I think BMW have switched to Conti's now as I didn't see any of them on the new BMWs at the dealer ship and that's a good thing!

They last but the grip suffers - I expect a tyre to be softer. Good levels of grip but give up too quickly on a track (too hard). Any water on the road and you feel more like on ski - this is probably due to the size, rather than the tyre itself. Good all rounders. Very strong - any non-RFT would give up on pot holes. I will never go back to non-run flats - first class technology, tested with no pressure during a BMW event - brilliant! I highly recommend the RFT for any enthusiastic driver with a powerful car. Those with comfort in mind should look elsewhere.
