general grabber A/T's are a cheap enough tire with similar results and thread similar to BFG all terrains, 265/75/16 if you have a 16 inch wheel. You don't need new shocks. Try taking off your mud flaps first and seeing what that looks like.
Bingo. Airing down is the best thing you can do in sand.BFG A/Ts work great in the soft sand when aired down. If your gonna spend a lot of time in the sand invest in an air compressor.
