I ran a set of baby swampers on my YJ before I lifted it, they were the 30-11.50-r15's, half bald, rode like SH**, got great traction offroad. But on my DD I couldn't listen to C/D's because the ride was so bad they would skip all the time, remember this is before lift and the stock springs rode pretty good.
I liked my TSL-SX's Bias ply, but when I pulled away from the tire store with my 31-10.50's BFG AT's I thought that there was something wrong because the ride was SOOOO much better.
I would say that even with my Rough Country 4" (stiffer than HE!! springs) the ride is still better than with the swampers. I don't think that on my DD I would run swampers again.
