What tire pressure to run with 32 inch load range C tires for best highway ride?

They are the BFGs that come on the 17 inch 2016 JK Rubicon Wheels.

I recently had a blowout with a BFG LongTrail, which might
have been due to low air pressure. Don't really know for sure, but I'm now more aware of tire pressures.

My take on this is to air up for safety instead of a good soft
ride. Check the max psi allowed on the sidewall, and air up
accordingly. I don't go under 32-33 psi on any tire anymore...

What width is the tire and what width is the rim?

for my 33x10.50 KM2s I run about 23 PSI, on my stepmoms Sahara with the rubi wheels and tires we usually run about 32-35, but its a lot heavier
