 To further increase the footprint, a centralized inflation system allows the tire pressure to be reduced from the cab for soft surfaces, then re-inflated for road use.The drive shafts were laid out like the US6, but as a mirror image, the front axle differential was offset to the left, while American trucks were offset to the right.Air brakes were used, on the ZiL-157 the air system also supplied the centralized inflation system.
