Being 10 ply I would say you could pick any pressure u want really. More so depends I guess on where/what the terrain is. I have 35" mrt x rox dd an there 8 ply an I run 8 pounds on all 4 corners with no issues but they do have kevlar sidewalls. I also have efx motoravage 8 ply an I run 10 in rear an 8 in front an have had no issues with them either. 8-10 psi range just simply has better traction all around, especially when rock crawling.
