If no one here has the answer, call Coker Tire and ask. They have a new line of radials that look very close to bias plies (Excelsior). They do require a tube, but with 35 Ford wires you want tubes anyway (leakage).

My Son Dan is talking about replacing the 16 inch bias plies on this rpu with these as we have been waiting for someone to come out with radials that look old timey, and these are the closest we have seen.

BTW, you probably already know, but make sure you run wheel adapters that are designed to properly center the 35 wires on your brake drums. Otherwise, the only thing centering the wheels are the studs, and these wheels are not designed for that.
