Filling Tires with Liquid Nitrogen
Filling tires with nitrogen instead of air can reduce air loss and boost fuel economy. But filling them with LIQUID nitrogen is an absolutely terrible idea since the stuff comes out of the jug at -320 °F (− 196 °C). That didn’t stop Superkot from trying it out on his Miata. It’s only a matter of minutes before the cryogenic fluid causes the tires to fail spectacularly.
