Anyone reading this, I have chosen to go with Vision Dually front rims all around with 225/19.5 tires. I ordered 12-16.5 tires thinking they were what was on the vehicle, that should be easy. I did not know in the last twenty years those tires have grown larger. Mainly the problem was the diameter went from 31.5 to 33 in,too large for Cortez. I felt dumb. I wanted the” original look” but now I don’t care. These new wheels will look great, and when I find a disc brake setup, I will have plenty of room for the discs.
