Over ten years ago, three sets of tires, and well over 75,000 miles, the Hutchinson beadlocks have proven themselves countless times. These DOT-compliant street-legal rims are built to last. Keep in mind that many of those miles were under a fully loaded 80 series Land Cruiser tackling some of the hardest terrain we could find. The only casualty being some minor scrapes around the edges.
Hutchinson’s design incorporates an inner spacer that securely clamps both the inner and outer bead at lowered or zero pressure. This increases traction, keeps debris out of the tire, improves braking, and makes the vehicle safer by reducing the risk of rollover.
A fear of mine was wheeling with a lot of weight up high, running low pressure, and losing a bead. Losing a tire on an off camber side hill being the worst situation I could imagine. That is no longer an issue running these and the peace of mind was more than worth it. 
On one trip a pinch flat destroyed a Toyo Open Country MT, said to have one of the toughest sidewalls, without any damage to the Hutchinson. Having these allowed me to drive to safety without the fear of separating a tire.
Through Rocks…
Mud…
Sand…
and snow.
They have performed flawlessly. Torqued to the recommended 100 +/- 5 FT-LB [136 +/- 7 NM], they have never leaked and required zero maintenance.
