'06 TJ. I plan to do some running on the beach, though mostly a DD. I plan on going to 33x12.50's primarily for the sand.
I think I'm learning that I should air down to about 12lbs when I hit the sand.
What are the advantages/disadvantages (if any) of steel v alloy with regard to airing down; and, given the above parameters would you recommend 15x8's or 15x10's?
