Continental's Grand Prix 4000 S boasts Conti's Black Chili rubber compound for 26% less rolling resistance, 30% more traction and 5% longer wear (than previous Grand Prix 4000 tires). This makes for one of the fastest tires in the peloton. Even better, the GP 4000 boasts a tough Vectran sub-tread for exceptional puncture protection, a 330-tpi casing for a velvety-smooth ride, and tread-wear indicators to eliminate guessing. If you're looking for the ultimate road tire, you've found it.

Continental's Black Chili rubber compound significantly improves wear, traction and rolling resistance through the use of carbon nanotechnology — microscopic carbon particles in the rubber. These mold better to the ground and have more points of contact to give the tire more grip. And, because the compound matrix is formed by more particles, which are connected more tightly with each other, the tire lasts longer. Plus, the smaller particles are more flexible, too, which improves rolling resistance.

Vectran Breaker is a synthetic fiber based on the natural model of spider silk. Processed into a multi-strand thread, it's lighter, more flexible and protects more efficiently against cuts than a comparable nylon layer. It also does not affect the tire's rolling resistance.

When these circular tread-wear indicators disappear, it's time for a new tire.
