35" KO2s: PSI on and off road

[JD Flick]

Hey guys, I know this may have been covered, and I saw the great chalk test thread, but I was hoping I could get a few opinions from people with experience.

What have you found to be the sweet spot for normal highway and city driving? And what pressure do you air down to when you go off-road?

My typical off-road terrain is sand and medium pack dirt.

Tires are 35X12.50R18 K02.

Thanks! for the advice!

I have 37’s which will be similar but when I had 35’s I ran 28 on the street and 12 on the dirt. I think you would be safe at 15-18 depending on your wheel.

I've got C rated 35's that I run at 30 pounds cold. I could probably go 1 or 2 less, but I just don't prefer to go below 30 on the street. I run 20 on the dirt, but with stock rims (narrow) they can go much lower. Narrow rims with a big tire are an old trick they used to call "The poor man's bead-lock." They are reputed to hold the bead VERY well.

Your rim width will have some influence on the sweet spot.
