Tire pressure is a crucial element of getting your rig’s power to the ground. The lower the pressure, the wider your tire’s contact patch and the more of the tire’s tread touches the ground. It also allows the tire to contour around uneven terrain, letting the rubber’s side lugs bite. That’s handy in all sorts of situations, including deep sand, snow, mud, and rock climbs. But on a normal wheel, lowering your tire pressure is a balancing act between getting the most traction and not unseating a bead. For most side-by-sides, that usually means running no lower than 11 or 12 psi. Beadlocks, meanwhile, let you turn that number down into the single digits.
