The Science of Speed: Tires & Pressure

Close up view of a tire. Caption: (Diandra) Higher temperatures mean molecules are moving faster.

NASCAR tires are filled with nitrogen to help protect against heat caused by friction. Friction also increases the air pressure in tires, and NASCAR drivers don't want a tire to blowout during a race. The use of nitrogen helps the crew predict how hot the tires will get. Part of "The Science of Speed" series.
