It's time to replace the worn out tires on my 4x4. I've been running 33" BFGs for quite some time. The truck has 4" Skyjacker springs in the front and slightly higher and stiffer in the rear. What is the maximum tire size I should consider without encountering any significant interference with fenders, radius arms, and the like? The wheels are 15x10 Eagles that are slightly offset to the outside (tires stick out very slightly). Everyone says 35s, but I've heard people running larger tires than that with milder lifts. I would definitely enjoy some extra clearance with 37s or 38s if possible.
