The Trailhead kit comes in two versions, a 5- to 20-psi version for Jeep and 4x4 owners, and a 15- to 40-psi version for motorhomes. In addition, the kit includes a helpful tire-deflation guide that can help a novice wheeler determine a safe tire pressure for many different 15- and 16-inch wheel-and-tire combos. Simply set the guide to your tire size, cross-reference the vehicle's GVW, and you are given a recommended pressure to air down to.
