Before you turn down that forest service road, there's one thing that'll change your whole day more than any part you could bolt on: your tire pressure. Airing down means dropping your tire pressure below the highway number you run on pavement. It's free, it takes five minutes with a decent gauge and a deflator, and it's the difference between a Jeep that fights the trail and one that flows with it. A softer tire flexes more, which means a bigger footprint touching the ground instead of just the center of the tread. On dirt, gravel, and washboard FSRs, that means better traction, a smoother ride, and less chance of getting bounced off your line. There are real risks that come with airing down too — done wrong, it can cost you a bead or a rim. This isn't something to wing based on one post. That's exactly what this page is for. Join us for the follow-up posts on how much to air down, what tools you need, and the tips and tricks that keep it safe. What's your go-to psi for dirt and FSRs?
