You will get a lot of opinions from folks about this. My general thoughts are as follows. Bias ply are what came on the truck. They fit and work. They will get flat spots when parked over time. Jack stands can solve that.They are getting more expansive and harder to find. They will work with inner tubes. They look great and are "correct: for the antique crowd.
Radial tires are better. They can be fitted just fine. They work great. They don't like inner tubes. They can also develop flat spots over time. They stop better. Roll better, and last longer. They ride better and steer better. They can be had from a local tire shop. The don't come with a wide white wall. Others will have some different ideas. Enjoy
