Regulation (EU) 2020/740

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.

Fantastic looking tyres, great grip even on tarmac, considering that they are mud tyres. Only fault would be the noise level, but you quickly learn to live with that when you see how awesome they look. Seem to be wearing well to, might get the 100000k suggested out of them.

Best off-road tires ever. I really abused these tires off road and in ice/snow and I have to say these tires are phenomenal. No matter what I throw at them, I always seem to have more grip then any other 4x4 with lesser tires. I highly recommend them.

Excellent tyre- very strong as well. Ive used these on tracks with very big sharp rocks, thought id wreck them but they didnt have a mark on them. In the recent snow, i also made it up a very steep, icy/snow covered lane which defeated a land rover with lesser tyres fitted.

Tires were bought for winter tires and i was very impressed with them my buddy called me to pull him out of a snow bank and i drove up the bank and around him with these tires great tires in my opinion
