3D software was used to design the tyre profile and do simulation tests to allow the best possible results to be gained before creating samples, maximizing the water dispersal, rolling resistance and performance of the tyre.
Wider section grooves between tread blocks allow better drainage performance. Serrated grooves on the tread block walls reduce road noise and quickly disperse water, whilst chamfered lateral grooves on the tread shoulder also help to reduce the rolling noise.
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.

17.01.2021fromMichal Main factor to buy them was A-rated wet grip at low price and I'm not dissapointed. Considering weight of my car it drives absolutely confident on wet roads as well as dry.

07.11.2020fromWilliam Willis The tyre ratings certainly do not lie, my Corsa Nurburgring grips very well in most conditions. The car itself was not developed to be a comfortable cruiser anyway, and the 225 35 18 is at the limit size wise I can put on without scuffing arches on fast cornering. The car will never break 50mpg anyway like a small modern diesel version can so fuel consumption rating was not a factor in buying, was all about the grip which these tyres definitely deliver.
