So my tires are Michelin LTX MS2 tires, size 245/75/R16.
The door sticker calls for 245/75/R16E tires. To be run at 60psi Front and 80psi rear.
Here are my weights from last year. I need to get current ones.
1) Loaded Van with no Trailer
Front Axle - 3,220 lbs (73% of GAWR): 1610lbs / tire
Rear Axle - 3,920 lbs (64% of GAWR): 1960lbs / tire
2) Loaded Van with loaded trailer
Front Axle - 3,380 lbs (77% of GAWR): 1690lbs / tire
Rear Axle - 4,740 lbs (78% of GAWR): 2370lbs / tire
Well the 245/75-16E are rated at 3,042# each, so to carry a bit further.
Unloaded
Front 1,610# = 52 percent of tire capacity
Rear 1,960# = 64 percent of tire capacity
Loaded
Front 1,690# = 56 percent of tire capacity
Rear 2,370# = 78 percent of tire capacity
Keep in mind you are only running 78 percent of the axle rating, the 80 psi is for the axles GAWR likely 6,084#.
I don't have a current link to an inflation table, but at that load 65 psi to 70 psi would give you the best contact patch from your tire.
