A lot will depend on the Service description which on the Toyo 37s will very with wheel size. The best way to get it figured out is with the chalk test, but with some extra details you can probably get a good starting point.

(Weight of your vehicle x 35%)/max load weight of your tire at max psi = % of max load
% of max load x max psi at max weight load = appropriate psi for the weight of your rig
Here is an example:
If your 2 door weighs around 4500 lbs.
(4500 x .35 = 1575) / 4300 = 36.6% of max load
36.6% x 65 psi = 24 psi for regular street driving
% of max load x max psi at max weight load = appropriate psi for the weight of your rig
Here is an example:
If your 2 door weighs around 4500 lbs.
(4500 x .35 = 1575) / 4300 = 36.6% of max load
36.6% x 65 psi = 24 psi for regular street driving
Additionally, inflation rates aren't necessarily linear and different tires are going to perform differently at different inflation pressures. I would strongly advise using the tire manufacturers worksheets or and ETRTO chart to determine what they believe the proper inflation rate to be. That doesn't mean you need to lock yourself into that inflation rate, but it is where the vehicle and tire manufacturer have determined to be safe. It also provides a good starting point to dial in ride comfort and handling. Then lastly, this is a good place to start your chalk test so you have given yourself a window of what will work best for you in the end.
