I'm using Falken WildPeak A/T (325/80-16) on my Mitsubishi Fuso FG and am very happy with them. For huge tires they balanced well (3 needed less then 1 oz, 2 needed about 2-3 ozs and 1 needed 7 ozs (ouch), I have 2 spares). When cold they have just a little vibration or road following, but once warmed up them run and track as smooth as silk. I'm running them at max pressure (55psi) since my truck is 12,000 loaded (10,000 empty) and even at that pressure they have really smoothed out the ride of my truck (the 80 profile is the big help). And they are very quiet, that is an important factor for me with next to no tire noise (as least on my noisy cabover truck). I can't speak as to wear/mileage as they are pretty new to me.
I got mine from Discount Tire Direct, great++ customer service, great price, free shipping and a $100 rebate
