"Continental Grand Prix 5000 is the successor to the Grand Prix 4000, with a 12% reduction in rolling resistance and a 20% increase in puncture resistance. Equipped with the latest technologies for optimum performance. BlackChili compound: This compound improves rolling resistance by 26% and offers 30% more grip than silica-based materials. Premium tires with BlackChili compound offer better performance and consistent driving characteristics from the first to the last kilometer, unlike many multicompounds. Vectran tread: Vectran is a synthetic fiber that is woven into fabric. Woven fabrics such as Vectran are lightweight and extremely durable. Exactly the characteristics we need for the protective layer on top-of-the-range tires from Continental. A Vectran protective layer is lighter, more flexible and more resistant to cutting than an ordinary nylon protective layer, without compromising rolling resistance.
