If you got P rated tires on your Tundra, go max pressure on the front. They are soft enough.
If you have some good LT tires, then match the weight to the pressure.
Not really a set formula, but in general if you're adding weight toa particular axle, air up as necessary. If you're unloading the front axle, then keep it at the psi you use when empty.
Example.
I run (in the summer) 60psi front and 45-50psi rear in my Doage 2500 diesel. Loaded up with the camper and a trailer in tow, I'm actually unloading the front (Cummins makes good ballast though!)since the camper c of g is just behind the rear axle centerline combined with tongue weight.
I knocked the fronts down to 55 psi to soften the ride a bit without too much tire flex and ran 80psi in back for obvious reasons.
