So, basically, no 37 us really a 37. Why? I mean, it kinda defeats the purpose. My Jeep is chipped at 35 1/4 which is my true tire size. I think that is garbage. Like we are gonna run the Rubicon at 50 psi.

I no longer have the tires so I can't take a measurement picture. Brand new, mounted on a 17x9 wheel under the jeep, they were 37 even using a level across the top of the tire.

(I know this is not the measurement method used here. Being that it is an uncommon tire in a rare size I thought I'd chime in).

Does anyone have a measurement on the BFG Krawler Blue Labels in 39x13.50r17?
