So for those of you that have swapped out the OEM tires for some AT’s or M/T’s what tire pressure you guys running? Seems like the load capacity for our OEM tires is 2555lbs at 33 psi so a 275 70 18 Load E tire would have to be at 42 psi to match that capacity.

Was just curious to see what others are running.

Same here. KO3 275/70 R18 E load with 42 psi (recommended by America Tires per this tire 10-ply sidewall)
 
I'm running 275/70R18 KO3's too. I'm at 40psi right now. When I did the math, I think going down to 35-38 would be OK. 40 is a bit bouncy. When they were put on they are about 35 and felt good, so I may air down.

I would go with the recomended tire pressure on the door frame: 33 ish. These tires are way stiffer than stock, so you don’t need 40 psi, in my opinion.
