It's been far too many moons since I've driven an auto w/bias plys.
When I got the 49 running with 600x16 bias plys still on it they didn't last very long, like maybe 1/4 mile before one flew apart and rode like a square so I went with radials and will stay that way. Granted the bias plys were very old but I decided to try radials on the OEM rims.
My 49 is a driver and the tubeless radials (225 75R-16's) on the OEM rims ride and handle great. I've got approx. 10K miles on a used set of Goodyear Wranglers.
I may checkout 215's on the next set of tires as I like the skinny tire look on a Stovebolt but I'm solidly in the radials camp.
