I've got the original sales brochure for my 1972 which I assume would be similar to a 1971. According to the sales information, depending on whether it's 2wd or 4wd, there were 6 tire sizes listed as either standard or optional for the 1/2 ton. The standard tire listed for 2wd 4600 - 5400 GVW and 4wd 5200 - 5600 GVW was a G78-15; the largest optional tire (4wd only) was a 10:00-16.5. There were 4 other optional tires listed as well.

Remember, this was one year newer truck.
