The secret is in the design. The extra wide PolyXBreaker effectively protects against foreign objects under the tyre tread. The continuous, three-ply casing effectively strengthens the sidewalls without adding more weight.
That lends the Grand Prix GT extra longevity at the highest level – earning it the tyre endorsement GT (GrandTour) and predestining it for marathons and multi-day races. BlackChili Compound and the tried and tested Grand Prix profile offer outstanding grip. – Of course “Handmade in Germany.”
