I really liked my KMC's for a budget priced wheel. The shell was super thick and they have the wide flat safety bead. No burps with 41.5 radial pitbulls at 2 lbs.
I had my hands on a set of dirty life wheels and wasn't impressed. Shell looked thin like a normal nonbeadlock wheel, plus the standard safety bead. I also don't like the lack of bolts on the ring. Especially since the hardware they provide looks cheap.
