For the record, I'm going to air down less from now on. 25 in front, 30 in back... on highway I'm more like 45/45. I'm fairly convinced that the DT's get too bulgy when you bring them down closer to 20, particularly in a heavy and loaded wagon.
And ride quality is still ok even at 25 in front, which could be the sole benefit of IFS..
