If they’d ever produce a set of 39” km3s, I’d post up what they are. their supposed to measure 38.5” but we will see
2015 JKUR AEV JK350
1985 Jeep Scrambler
So I did see a set of KM3 39 for sale second hand... ( New with labels on, stated he was going in a different direction) on the floor no air not mounted they measured 38.5+. Figure with air and a 6000# jeep they should come out to around 37ish static at 30ish PSI. On the road rotational forces would spin the tire to closer to 39 inches.
