This Mean Mother 2-in-1 digital deflator kit makes deflating your tyres quick & easy. Reducing your tyre pressure is a big part of going off-road; it increases the tyre footprint, which greatly improves your traction and reduces the chance of getting bogged in soft, muddy, or sandy conditions. Reduced tyre pressure also allows your tyres to absorb rougher terrain as the tyre rolls over an obstacle, for example a rock or tree branch. This absorption assists in maintaining momentum of your 4WD.
