That's a 35" tire. If you search 35" tires on the Ram, they have front/back interference with the fenders. Some have documented the modifications they have made.
ORG and Rebel are 1" higher from the wheel hub to bodywork. A 34" tire, a 285/70-18 adds one inch in radius and should have OEM fender to tire clearance. A 35" adds 1.5" and may or may not have an issue...but would require the smallest front leveling...height-wise.
However, at full lock, the tire will also move closer to the truck. That may or may not be a problem with inner front fender/frame clearance. The fix would be to use a small spacer (5mm-10mm) or a wheel with less offset (+12mm, +10mm) which would move the wheel outward 1/4"-3/8". It probably would not need more than that.
