Why Deflate Tires When Driving into the Desert?

[LeArcher]

Deflating tires when driving into the desert is done to reduce tire pressure and minimize the risk of blowouts. Here are the relevant details: 1. Overview: It's essential to deflate tires when entering the desert. The high desert temperatures make lower tire pressure crucial for reducing blowout risks while simultaneously increasing tire-sand friction for better traction. 2. Precautions: Avoid gear shifting during dune climbing. Before tackling steep sandy slopes, misjudging speed or slope conditions may lead to downshifting near the ascent point. While this maintains high RPM and power output, the downshift impact can abruptly reduce vehicle speed due to engine braking. A stalled vehicle attempting to climb while accelerating will gradually lose RPM as engine load increases, potentially causing engine shutdown or even getting stuck mid-slope.
