Cooper Tires is launching the Discoverer M+S Sport, a new range of winter tyres to meet the needs of high performance 4x4 vehicles. Designed to provide excellent traction during snow and icy conditions, the Discoverer M+S Sport's tread design incorporates biting edges to offer unparalleled grip in treacherous conditions. Cooper's patented 'Snow Groove' technology capitalises on the higher traction characteristics of 'snow on snow' grip - rather than 'rubber on snow' - while simultaneously ridding itself of unwanted snow build up in the tyre's grooves. The Discoverer M+S Sport is available in T, H and V speed ratings to cover 15- to 19-inch rim fitments. Cooper introduces a variety of new sizes in H and V speed ratings, allowing the tyres to be fitted to an even broader selection of today's high performance vehicles. The Weathermaster Snow benefits from all the characteristics that make Cooper's Weathermaster line successful, including a unique tread pattern which optimises the tyre's road holding capabilities in both wet and snowy environments, whilst working in harmony with the vehicle's braking system to minimise stopping distances in slippery situations. The Weathermaster Snow is available in a wide range of sizes to cover 15- to 18-inch rims. Both tyres also benefit from a high silica compound which, together with extensive siping, helps keep the tread blocks flexible at very low winter temperatures, aiding grip in the wet and traction in the snow.
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.

16.02.2015fromHarvey Woods Tyres are excellent, quiet and wear well. Winter has not been severe but car has been sure footed in the snow and ice we have had when I know colleagues have struggled on the same roads. I am pleased I bought this brand and I would happily recommend and buy them again.
