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.
37/12.50x17 KM 3
Mounted on a 9 inch wide rim at 30 psi, are 35. 1/2 tall. Diameter unloaded is a tad over 36 inches.
