I ran a set of NOS 8X19.5 Goodyear tires on my 1 ton. I had a rebuilt front end and steering, and drove up to about 55 mph. I had no problems, and they drove fine, even took me around the country, about 8,000 miles.
I later put radials on the truck, and while there was no problem before, there was a big improvement in the ride and handling.
I doubt I ever buy bias tires again, unless radials are not available in the size I need.
