They did great, I only dropped them down to 20 psi and they walked up/down/over everything I was willing to try with a near stock truck. I had to lose some of the fender in order to be able to turn and still stuff them, although they do still rub a little. I never would have thought that an extra 1" of ground clearance would've made it feel so different.
The only problem that I can foresee is that they're made of a soft compound rubber, so I'm not expecting them to last for very long on a daily driver that averages near 30k a year.
