I've put a few sets Duratracs on various vehicles, never see any problems or complaints; just did a set on a Tundra I lifted a few hours ago. Only thing that concerns me is the side wall thickness. For everyday driving I'm sure it would never be an issue, but I wouldn't want to rely on them for a Raptor run. I compared the thickness to a Regular BFG TKO, and a BFG KM2. The duratrac was definitively the thinnest of the group with the KM2 being the thickest. Maybe the Kevlar fibers make up for the sidewall thickness... I dunno, seemed pretty damn (scary) thin.
I have a set of generals. They do wear faster than a regular tire, but the wear is even; possibly because I'm overly **** about my alignment. I think they do better in the mud then the stock tires, I wouldn't say they're horrible in mud.. But I do not daily drive my generals, they're just too damn heavy for my liking. I have two sets of wheels. The stock BFG's are mounted to the OMF wheels I bought from Bojangles, these are my daily driver wheels/tires. The generals are mounted to the original stock wheels. I really think this is the way to do it, have a set mounted up for D/D and a set mounted up for off road.
