I have Jeep Canyon aluminum wheels (8" wide) and the highly regarded TrXus 31"x10.5" M/Ts. I used to air down to 12 to 14 psi and lost a bead 6 times in total - threw on the spare tire and kept going. National 4WD (where I bought the tires) cleaned out the tire and rim and remounted my tire 5 times before they got tired of it and made me pay for the last bead I lost. I now run 16 to 17 psi and haven't lost a bead since. Less traction - probably, but losing a bead is a PITA. Not sure why I lost so many beads with relatively high tire pressure, was my rim alittle too wide for a 10.5" wide tire? Flexible sidewalls on my TrXus? I can't justify buying beadlocks with the amount of time I devote to wheeling, the wheel weight and my 2.5L 4 banger.
