My Blackwaters a 22x12.5x9 and INDESTRUCTABLE.
They are not only for 4x4's. This size has a flat profile like Holeshots, Razr's, or Bandits. They're a lil heavier but WELL worth it in MUD, SNOW, or SAND.
They are bi-directional so, one way is suited for hardpack and most conditions, and other way has more "scooping" capability for deep mud and sand. I kept mine the hardpack direction and barely ever get stuck unless I hang it up or float it in too deep mud/water.
This is STILL declared one of the BEST tires ever designed.
