Reducing your tyre pressure is a big part of going off-road; it increases the tyrefootprint, which greatly improves your traction and reduces the chance of gettingbogged in soft, muddy, or sandy conditions.A reduced tyre pressure also allows your tyres to absorb rougher terrain as the tyrerolls over an obstacle, for example a rock or tree branch. This absorption assists inmaintaining momentum of your 4WD.
