Wouldn't it be perfect if we could apply high pressure right at the tire's beads, independent of the pressure in the balance of the tire? Staun's Internal BeadLock™ does exactly that. It is literally a specially reinforced mini-tube right next to the bead. Sold for off-road use only. Excellent Technical Information can be found here:
