2019 Ram 1500 Rebel QC. I've got 37x12.50r18 tires on it with a max PSI of 65. I have been trying to figure the proper PSI to run them. At the moment they are at 30 in the front and 25 in the rear. I did the chalk test a few times which is how I got to those pressures before I had decent tread coverage. Is that too low? They seem fine but I'm paranoid. I assume it's fine with how much volume there is in the tires for air but I figured somebody else with 37's might know for sure.
