Continental 0118356 Grand Prix 4000-700 x 20 Black Tire with Black Chili is one of the few tires that miraculously delivers on all fronts. It is light, offers tremendous puncture protection with Vectran, and provides amazing handling and low rolling resistance thanks to Black Chili. 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 material is extremely tear and cut resistant and is also flexible. It retains these properties even under constant stress. The new Black Chili material incorporates rubber compound particles roughly ten times smaller than what is typically used in bicycle tires. This creates a denser rubber, without adding more material. Denser rubber increases a tires ability to conform to the road, while also increasing durability. The Black Chili compound is also more resistant to UV rays, which contribute to cracking and premature tire wear. The Grand Prix tires also come equipped with tire wear indicators so the rider knows when to swap out tires. Specs: Color - black/black skin foldable; Black Chili - yes; Weight - 180 grams; Recommended PSI - 130; Maximum PSI - 160; PU - 10.

In my experience, the difference was subtle when you are rolling out on your first ride. The ride felt harsh to me but that was probably because the PSI was initially a bit too high for me. Lowering the PSI to around 100-110 has made the ride feel more comfortable. In my opinion, there's no need to be running clincher tires at such a high PSI. Decreased rolling resistance does you no good if your tires are beating you up every time you hit a pebble on the road...
On the open road, at fast speeds, the difference between these Contis and the Armadillos becomes more noticeable. The tires just "grip" better, helping to propel you forward.
Durability is excellent. Over the current ~1000 mile lifetime of my pair, I've only experienced 2 flats. That's right. Only 2! I'd say that's pretty good considering the rough roads I tend to ride on. Pair these tires with a tube like Vittoria 700 x 19-23c Ultralite Tube and you've got yourself a good ride.
I'm now using black ones that didn't have that issue.
One other thing, from what I've read the GP4000 with black chili is the same tire as the GP4000s, they just have different graphics.
I ride recumbent bikes which makes changing a rear tire a bit more difficult than on a diamond frame so I appreciate the puncture resistance of these tires. I get 3500 - 4000 miles before they are worn enough to consider replacing them.
