For the coloured GP 4000 tyres, the activated silica compound improves the handling at stability limits and gives minimal rolling resistance. The anti-tear formula in the rubber compound prevents tread brittleness while increasing mileage performance.

The patented Vectran Breaker reconciles the conflicting goals of low weight, low rolling resistance and top puncture and cut resistance in a fascinating manner. The Vectran fluid crystals fibres were developed for airbag systems in the automotive and aerospace industries. The material is extremly tear and cut resistant and is also flexible. It retains these properties even under constant stress - as opposed to Aramide.
