I'm not running them but for that size 28-32 will be the proper range. Start at 32 and work down from there to find the sweet spot.

Thanks for the response. What are you basing your answer on?

I know you said KM3 but I run Ridge Grapplers, D load range 37’s at 28psi

I run mine at 26 psi cold.

I cannot give you that answer, however I can supply you information about the KM3 35x12.5x17, I run them happily at 32.

Owning 50+ 37-40 inch tires. Over time you figure out what works best.

Unfortunately, or Fortunately . . . . . the KM3's characteristics are nothing like any prior MT's. They were conceived with a different design intent.

I am running the km3’s, not in a 37” but a 39”. I have worked my way down to 28/29 psi and the happy point.

Thanks for the info. I was thinking about starting at 32 and work from there

Correct pressure depends on the weight being supported so is different for different setups. Get some chalk and find the pressure that produces even wear.

I am currently running 30psi on my 37” KM3’s. It’s a hair too high. Going to drop to 28psi.

Tried them at 30 and ended up dropping them to 28. Seems like the right pressure.

I'm at 30 psi with mine. That's been working for me.

I keep them around 28-30 seems to be about right so far. Their getting ready to hit 10,000 miles.
