Why Deflate Tires When Entering the Desert?
2 Answers
In the desert, temperatures are relatively high. Deflating the tires reduces tire pressure, minimizing the risk of blowouts while also increasing the friction between the tires and the sand, thereby improving traction. Reasons for deflating tires: During hot summers, tires generate heat during long-distance travel. Since air expands under high temperatures, it is necessary to appropriately deflate the tires. Precautions for deflating tires: When driving on low-traction surfaces such as sand, snow, or marshland, it is essential to deflate the tires to increase the contact area between the tires and the ground, ensuring better maneuverability. Insisting on off-roading with high tire pressure not only reduces passability but can also cause damage to the vehicle.
Let me start from the beginning about deflating tires when driving into the desert. The main purpose is to flatten the tires slightly, increasing the contact area between the tread and the sand. This reduces pressure and makes it less likely to get stuck in soft sand. Once, I forgot to deflate, and my wheels just spun in place, almost trapping me in the vast desert—it took a lot of effort to get towed out. Since then, before every desert adventure, I stop to check the tire pressure and reduce it to between 15 and 20 PSI (normal road pressure is around 30 PSI). The car feels much more stable, with better traction and reduced bumpiness, making the drive more comfortable. Be careful not to deflate too much—below 10 PSI risks tire bursts and rim damage. After leaving the desert, be sure to find an air pump to reinflate. Preparation is key—bring a tire pressure gauge and inflation tools, and don’t underestimate this simple step.
