Well, they worked quite well on our test TJ.
we had two tires that went down overnight to flat from the install till we loaded them on the trailer sunday morning.
they where leakign around the bead on both due to the old alluminum rims pitting on the bead. one we got to fix, th eother we didnt have time, so the left rear was goign down fast.
on consensous on the locks. they did work well!! they did keep the tire bead seated. they did allow mud and twigs, and bark to start to work into the bead, but the TJ driver worked them extremely hard.
the left rear went flat half way through the day. we drove out of the park with that tire COMPLETLY FLAT on sidehills, uphills and offcamber to that side. it tried all it could to peel the bead off, but the bead stayed planted for the 1 mile ride out.
type of wheelign we wanted to test them in
on this hill you have to cut it up high in the very right top corner and "slide" sideways to the bottom as one of the few lines to make it through without pulling cable.
you also have to watch the giant hol by my rear tires as its deep enough that if you slide in you roll over.
this is the trail ultimate adventure ran at the cliffs and rolled 3 or 4 trucks in this corner.
you can see the heavy side load we put on the tires doing this with 4-5lbs of air.
i did the slide sideways all th eway down with the 2 driver side tires in the air till i pegged the tree as you guys can see in this pic.
also has to take the sideloads of winching our trucks on our sides
the test tj running between 5-6 lbs of air
these are th etype of side loads that are always peelign normal tires off the rims
