Ideally if you choose to run psi in this range at the minimum you should choose ultra-heavy duty type inner tubes (3mm – 4mm thick) you still run the risk of “pinch flats” from debris and square edge hits, but the thicker rubber tubes offers added protection. Another consideration would be choosing tires with added construction strength or additional carcass plies, generally noted with A/T (all terrain) Desert or Rally markings. This is not a common pressure range and would most likely only be considered for Enduro Extreme & Super Enduro application. There are a variety of “Bead Lock” systems or products on the market which fall into this pressure range category (Tube Saddle, T Lock Concept, Tube Guard, Tubliss, etc.). All of these systems are in place of running the basic inner tube, but keep in mind that TT (tube type) off-road motorcycle tires are not intended to be used in a tubeless application. The air will not seal inside the tire and if a foreign object is introduced (a cut or puncture) the tire will be rendered out of service.
