The energy lost when a tyre is in motion is known as 'rolling resistance'. This has a direct impact on fuel consumption. A tyre's rolling resistance score ranges from A to G. Over the life of the tyre, fitting an A rated tyre could save you up to 6 litres of fuel when compared to a G rated tyre.
The exterior noise grade of a tyre is expressed in decibels - accompanied by one, two or three sound waves, with one wave being the best noise level performance. To achieve the best grade, a tyre’s noise level must be at least 3dB under the legal limit set by the EU.
A tyre's wet grip capacity is expressed in Grades from A to G. The difference in braking distances between each grade is roughly 3m - an average car length. This makes average stopping distance between an A and G rated tyre 18m. That's 4 car lengths.
The solid, sturdy central ribs, attached tread lugs, plus asymmetrical tread ribs ensure optimum, longitudinal stiffness in the tire and reduced movement in the tread. This means steering forces are transmitted straight to the road.
A supple macro-block design on the outer shoulder and solid central ribs, ensure that the tire adapts perfectly to the road surface. Particularly during fast cornering the contact patch is increased. The driver receives excellent feedback when approaching the limit and the tyre provides outstanding grip with maximum stability.
Black Chilli Technology is a specially developed compound technology involving an innovative type of racing grade carbon black, which ensures a speedy warm-up process and greater stability. The polymers in the compound are reinforced with nanoparticles, making them extremely supple. Thus they provide more contact points with the road, so grip is substantially enhanced and the tyre far more stable. In addition, special grip resins provide optimum interlocking with both wet and dry roads, thus achieving shorter braking distances.
Rolling resistance-optimised ‚cap and base' tread.
The two tread components - ‚cap' and ‚base' - complement the balanced compound concept and ensure good grip in the wet, whilst at the same time providing short braking distances and reduced rolling resistance.
The ‚cap', on the outside, provides good grip in the wet and short braking distances, whilst the ‚base', on the inside, reduces rolling resistance. Together they achieve more positive road grip and retain kinetic energy, whilst simultaneously ensuring high safety.
