Tire Pressure Question for Magnitude/Omni’s

What pressure are you running?
I understand that weighing all corners is the best way to determine what pressures should be used, I have weighs on CAT scales with different loads but have been unable to weigh all corners as of yet. I’m curious as to what others are running for pressures on your Mg/Omni with a traveling load. I’m running 90/105, door label says 95/110
Thanks in advance

F 85, R 105. Based on my scales weight I should be at 100 R but I bought a 110 PSI Crossfire before I figured the weights, and to keep a visible Crossfire indication cold, I set the rears at 105. I weighed with 1/3 fresh water and loaded 90% for travel so the extra 5 in the R will be fine with more water. Note the 100 I stated was for when I got to 100% travel loading. That 100% for me is under GVWR.

Thank you both for your feedback, much appreciated. I did the math this morning and if I have it right this is what I came up with.

Based on a few different Cat Scale Weighs my typical running weights are:
6,700 Frt Axle divided by 2 = 3350
12,700 Rear Axle divided by 4 = 3175

The Continental chart shows me that setting pressures at 90F/100R would still provide a little cushion for unequal side weights and be just fine for my running weight.

I will be dropping the rears down to 100, maybe that will keep a few more screws in place…

Thanks again for the feedback on what you are running.
