Optimally arranged blocks with transverse incisions in the centre ribs and shoulders considerably improve grip on snow. The special arrangement of multifunctional sipes ensures a better grip in all directions when in contact with the road surface. The special profile design in the middle improves the lateral grip on snow. This results in exceptionally good traction, short braking distances and safe driving on snowy roads.
Optimized positioning of the longitudinal grooves and lateral grooves improves water displacement from the tread on wet roads. Additional carvings in the shoulder area ensure optimum contact with the ground, which improves contact on wet roads. This arrangement of lateral and circumferential grooves ensures balanced, safe performance on wet roads.
An improved tread structure with differently graded blocks whose length varies on both sides of the tread minimizes rolling noise. The resulting low noise level leads to a relaxing ride and less stress for the driver and other passengers.
Tyres with high wet grip performance (A or B graded) have shorter braking distances on wet roads and are, therefore, safer in the rain. As with fuel efficiency, the D grade isn’t used and there are no plans to use G.
Tyres account for up to 20% of your vehicle’s fuel consumption so, if you want to get more miles per tank of fuel, you should choose tyres with a high fuel efficiency rating. You will also lower your CO2 emissions. It comes down to rolling resistance i.e. the energy lost when a tyre is moving. The lower the rolling resistance, the less energy is lost and the lower your fuel consumption and CO2 emissions. The difference between an A-rated tyre and a G-rated tyre could be as much as 6 litres per 625 miles.
This is the external noise made by the tyre and is measured in decibels. The more filled bars shown on the label, the louder the tyres.
