For a DD you will be very disappointed with the Swamper TSL SX's. With the SX's on my truck it hops up and down and all around, I'm bouncing up and down in the seat. They work great off road and that's the only place I'll use mine. BTW - mine are Brand NEW 36-12.50/16.5 and have been balanced, the tires are just very out-of-round. I know it is the tires because when I got my new 35-12.50/16.5 General Grabber MT's (NEW off ebay for $440!!!) I took the truck out and had no shake/hop/vibration all the way up to 90 mph, and they have NOT been balanced!
The brand you decide on doesn't matter very much, just get something that is a radial and you will likely be happy.
