Lab Tested - What's The Fastest Road Bike Tire?

What's the best road tire on the market? Is there really much of a difference between the best ones?
(NOTE - The Continental GP4000 S2 was tested, but we accidentally left it out of the list of tyres at the start of the video)
And what air pressure should you use in yours? We sent ten of the best road tires to Wheel Energy for testing, and did plenty of our own tests in Boulder, CO too.
