I heading back to Big Bend National Park next week and will be driving many of their awesome backcountry roads. I plan on lowering my tire pressure once I get there, but what do you guys think is a good compromise pressure for leisurely cruising moderately rocky/dirt roads and then driving 30-40 miles back to camp on pavement. The speed limit in the park is 45 mph so I won't be driving super fast. Temps will be in the 60s and my LX will not be heavily loaded.
I have BFG KO2s 275/65/18 E-rated and run them at 40 psi. I have a deflator and decent portable compressor but don't really want to air up/down several times a day.
I understand that low tire pressure can cause excessive heat, handling issues, etc and I don't want folks to get too excited, but I'd like to hear some anecdotal information on what others have run.
