in the 1980's the Light Duty 3/4-ton got 215/85-R16's and the Heavy Duty 3/4-tons and 1-tons got 235/85-R16's. Dually's came with the 215/85-R16's.

In the 1970's it was either 7.50x16 or 9.50x 16.5 - I could be wrong on the 16 inch size, any 3/4-ton from the 1970's that I have owned came with the optional 9.50x16.5's
