Ditto... 10" wheels "sink" more in the sand. Like they were saying, a 8" wheel has more tire and helps "float" on the sand instead of trying to drag through it.
I went to a 21x12x8 Brat from a 20x10x10 hauler and kick myself in the ass everyday for spending the money on that size hauler. My Brats are a night and day difference. :fro:
