I haven't run them on my Model A, but on my old 50's cars I was worried that they would ride differently.
I did use them and liked the smoother ride, especially when first moving; the bias tires had a memory and would have a flat spot for a while until they heated up.
Also the radials looked a little funny, like they needed air but that is the nature of the beast. If you want that tall "on the tread" look you will not be getting it.
Most likely safer and easier to replace on the road if you have trouble.
Just my humble opinion.
