Thanks Crimson. My ATM's drove me insane. Way too loud for an AT tire with that tread (even Duratrac's are quieter), and wet traction was terrible. Even being in 4wd all the time, I had issues slipping and sliding on wet pavement. It was to the point that I didn't feel safe with them. I had 32k miles on mine, still have 50% or better tread. Hated to buy new tires, but the way it drove on those ATM's, it was gonna either put me in the ditch or another rig.
I was really concerned about the body mount chop. From what I've read, it'll be fine on road, but may rub off road when flexing. Living in the city, I don't have much of an opportunity to flex until I head back home on the weekends.
Like you said, I didn't want to really lift the body off the frame, but didn't want to hack up my fenders either. The 1/2" body lift was perfect, did exactly as I hoped.
I've got the understanding parts will wear faster, and I accept that. As you said, whether it will be a noticeable decrease in life is still debatable, but the difference is there.
MPG is going to be the big factor. I'm hoping to stay at 15 or better, but we'll see. According to the lie-o-meter and a little city driving, it looks promising. It'll be another week at least before my first full tank with the new tires. I'll post up once I get a chance to do some actual calculations.
