I thihk the 22x11x8's have too much side roll for duneing. I'ld look into 21x12x8's 9 or 10 pdl extreme's. They have about 68" roll out and is a pretty good tire for drag/dune combo. You can get a set from RMATV for about 250 shipped compared to the 350+ for the super lights and they're more durable for the dune riding.
Just my 2 cents
