Here's how the wheels of the supersonic car are made

When you're trying to build the fastest car in human history, like the guys making the Bloodhound SSC, you have to make wheels that basically re-invent the wheel. To reach 1000mph and go supersonic, the wheels they're using weigh over 230 pounds, nearly 3 feet wide and spin four times faster than a F1 car. » 7/15/14 11:10pm 7/15/14 11:10pm

We Didn't Know How Tire Sounds Are Made Until Now

A Double Chamber Bike Tire Helps Prevent Flats When You Ride Off-Road
