Great wheel, as close as you can get to a beadlock without going to one. I air down to 10-11 PSI on the rocks with no issues at all, sidewalll flexes, deforms, etc, folds in on itself and I haven't lost a bead, I did at 7 PSI but that's because I turned right into a rock, caught it just right.
The only downside is that they'll get beat to smithereens if you do alot of crawling.
