BFG ko2 tire pressure

[Danplante]

Got myself some nice ko2s and noticed that the rating on the tire is 80 psi. I know they are used on all kinds of vehicles and the tire pressure varies with the vehicle. I have mine at 40 and I own a 2008 trd sport long box crew cab. The tires are 265/75r16. What tire pressure would you suggest?

I would start at 34-36 cold and do the chalk test when you have a few miles on them. I have 285/65X18 and the tire shop set them at 38 cold.
