Truck tires

[Sunnybrook Farm]

I found a Ford V8 1934 1 1/2 ton truck that I can buy fairly reasonably but I am concerned with the tires. Are there modern sizes that will fit the old rims or possibly modern rims to fit? I have researched it but most original options seem real expensive for these tires and wheels to have been used for decades, I feel like I am missing something in my research.
