Anyone run these on there KJ? I run them on my 2wd truck I love them, they were a tad faster then I'd like but I dig them. I had one defective one on truck (Side wall completely distigrated), got another, no problem yet. Anyone use them? What are ups and downs? Obviously I dont go offroading in my 2wd, they're on there for snow and crap. I know there throw rocks.
