My good friends and completely trusted (senior) colleagues TomO and kubes40 have accurately, fully and completely answered this question. After previously following their same advice and completely restoring a '47's running gear and suspension to as new conditions I never experienced the problems described with bias plys over thousands of touring miles. The car was a pleasure to drive with 3 1/4" www on 7.00 x 15s. Never looked back, never had a problem AT FORD'S RECOMMENDED 26 psi rating (for the Mercury). Have personally seen two (so far) original EFV8 rims that cracked - catastrophically - with radials installed. My mind was already made up from experience, these visuals simply sealed the deal. If you want a custom car, build it to be custom with all the necessities to ensure it is safe for the features you wish to add (like radials). Don't piece-meal it and expect it to work like a modern car would with 70-90 year old technology as the foundation. As for me and my house, well, drive it like it was meant to be driven, like it was meant to perform, before you decide you have the knowledge, experience and expertise to improve upon it. In most - dare I say all - cases you will find Ford knew what the h*ll they were doing. Steve

I had radials installed on my '41 coupe and am very happy with them. The car rides and handles much better. It does not wander all over like it used to. I used my stock rims with tubes and no problems there.

Big Vince, did you click on the link that I posted that describes the different way that radial tires stress the rim? Read the article and then make up your mind. Your Woodie is a big sail when a crosswind comes along. The big 18 wheelers move my wife's 2013 Equinox when they blast by at highway speeds. The Equinox has a much more sophisticated suspension and steering gear than your Woodie, but it too is a big sail. Radial tires will not eliminate the sail effect. I drive my 40 Mercury on all kinds of roads and do not find that it wanders or has bump steer. My 53 Lincoln did have that problem, but after I had the front end aligned it tracks very nicely. Both cars are affected by a passing big truck or a strong cross wind. Tom

As you are worrying about stress also look at the as new thickness of the steel in the rim of old and new. The old is thick the new is high strength and thin expected to be stronger because it is "high strength steel." Unless---the stamping press thins the place where the rim shape rolls into the bead side. Then you might see a feather of bead edge that has cracked off and exposed the side of the rubber bead. Hopefully after so many years and miles this kind of product defect has been weeded out or never existed in these old Fords. I saw it on my friend's 1968 Chevrolet C-10 and immediately looked at the much thicker 1955 passenger rims on my 1948 Ford after I converted to 4-1/2 inch bolt circle. Look at the metal on your wife's rims.
