37” BFG KO3 Load C

[2021Willys]

Has anyone got the new BFG KO3 tire in 37x12.5 in Load C? They were supposed to be released in June. Do they run smaller like the K02? Anyone have any pictures?

KO2's don't run "smaller". In reality all all-terrain tires run smaller than mud terrain tires. This was a big misconception when most people were only running Ko2s and didn't have experience with other all terrains. I think this is due to the KO2 being alot of peoples first "big" tire, thus its the first tire they really paid attention to the tire size on, and are shocked to find its smaller than the advertised size. When in reality you'd be hard pressed to find an all-terrain that measures exactly its advertised size under weight of the vehicle. This is normal.

When people say they run smaller it's that they are measuring hub to floor not actual circumference. Bfgs aren't really any smaller but they do squat quite a bit more than most AT. I've had bfgs in 39 and 37s, both required 38.75 and 36.5 to get accurate speedos which was a different measurement than if I just went hub to floor x 2

Every bfg ko2, ko3, and km3 I have purchased runs small. I have 5 work trucks with them in various metric sizes, wheel sizes, and load ratings. The current set of km3's i have listed here even unmounted barely measure 35"

Exaclty I agree with you, it is all tire brands that measure up smaller to get an accurate speedometer. Heres two examples of 37x12.5R17 tires, Top is a falken 37" measuring at 35.5 and bottom is a Toyo (a brand everyone says runs "true" to size coming in at 35.5.) This is perfectly in line with my 37" Ko2's measuring up at 35.5 with the weight of the vehicle. I just fail to see how they uniquely run small when people call out the Ko2 specfically.

I can only speak to personal experience. In my group there are several different choices of tires, and we mount/balance them because we have a tire machine. I have never seen a bfg be even close to marked size, however, toyo, falken, tsl, and milestar will generally be much closer. Those overall heights are mounted tires in free standing (no weight) situations. Obviously those measurements get even "farther off" when on the vehicle loaded.
