Chevy recommended 24 PSI front and rear.
Chevrolet recommended a few different PSI for 4 different 15" truck tires , depending on the tire (as high as 48). Tiny's link is for a passenger car tire/load.

No 7.00x15" is listed, so checking the PSI at different loads given by the tire manufacturer might be a good place to start?

The 1949 Truck Data Book shows a variety of PSI for each size of 15" truck tires, depending on the load.
