SW-7 is designed to optimize grip in Nordic winter conditions. Advanced stud hole design and formula retain its braking and acceleration grip on snow and icy road surfaces.
Center rib and directional pattern design enhance straight driving performance and manoeuvrability on snowy ground. Wide and zigzag lateral grooves plus big void ratio design enhances the ice-pillar effect and reinforces grip on the snowy road.
Serrate multi-sipes design shortens braking distance on snowy and the icy road to reinforce braking performance and driving safety on icy ground. Tri-dimensional sipes design on tyre shoulder enhances block stiffness, manoeuvrability and cornering performance on the icy ground.
Circumferential and random-allocated spike holes design on tread pattern reinforce traction on the harsh icy road. Unique silica formula used for all sizes enhances wet grip. Ha-oil free formula used for all sizes conforms to European Union’s environmental protection standard.
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.
