The culprit responsible for increasing tire pressure during a race is friction. Using dry nitrogen gas helps the team predict how hot the tire will get and how much the pressure will build during a race. Here, race car driver Brian Vickers' Red Bull pit crew changes all four tires during a pit stop. "Tires & Pressure" is episode six of the 12-module video series, "The Science of Speed," by project partners the National science Foundation and NASCAR.
