One of the simplest and most dramatic adjustments to your rig that will improve your trail capabilities is airing down your all terrain tires from highway pressure to trail pressure. A small reduction in air pressure can have a dramatic effect on traction, floatation and the overall trail manners of your truck. Even though the concept of airing down tires for off road driving may seem complicated, the process is simple and the needed equipment to do so is affordable.
Whether you are new to overlanding or already spend any time on trail, you should really consider trying lower tire air pressure to match the conditions. You can greatly improve your traction by adding up to 80% in length and 20% in width to your tire’s contact patch with the ground. When this contact patch increases so does the amount of friction with the ground. Decreasing pressure can often be the difference between crawling over arduous obstacles or wheel spin. While this lower pressure should only be used off road, the benefits while overlanding are numerous.
