Sometime in the early 1980s, I was on one of my first four-wheel-drive trips with my new Toyota Hilux. Stopping at the trailhead, everyone started letting air out of their tires. Clueless as to why I asked one of the guys, “Whatcha doing?” With his two-word reply, “Airing down,” I asked the next dumb question… “Why?” His brief explanation, which included something about traction, began a multi-decade edification on the merits of reduced air pressure. What I’ve learned is that in the same way the Inuit use many words to describe snow, there are numerous variables when it comes to airing down. In this Backcountry Skills, we’re diving into the why, when, and how much when it comes to lowering the bar.
