Air down pressure for 275/70/18 KO2

[SICARIO]

either I can't use the search function or this hasn't been specifically discussed. Trying to determine an optimal air down pressure for mild/intermediate off roading.

I have 275/70/18 KO2's on stock rims (LX470), stock weight.

Most would say between 20-22 psi off-road and 38-41 psi on-road. If it's just gravel road and no real rocks, I might only go down to 30 psi to take the "edge" off the ride.

Thanks, I'm in the right ballpark then.

I think most people will say that it depends on the precise offroad terrain. If it's relatively deep sand I'll probably go a lot under 20, but if it's challenging unmaintained roads It will probably be considerably higher unless my traction is suffering. For perspective I'm at 40psi on the road with that setup.

Same tire size here and I always go down to 20 or slightly less...

15-20psi is safe depending on how loaded down your truck is. You could prob go even lower. The KO2 has a 3ply sidewall and can handle low psi.

I run this exact combo and run between 15-18 when off-road and 36-40 when on.
