A couple more thoughts. I run all used bias tube type tires on 2 heavy trucks - a 59 GMC 10 wheeler and a 58 Chevy 6 wheeler. They are on split rims, but not the Firestone 'widow-makers'. These are not regularly driven. I look for used Goodyear and Firestones Made in USA. They are tough tires and will last for many decades if trucks are parked inside. They are cheap partly because people are afraid of them, but old bias tires are less likely to blow out than radials unless the radials are relatively new (my experience/opinion). Radials age worse and they don't like 'sitting around'. My bias tires smooth out within a mile, but yes it is pretty rough starting out. To each his own, and I'm just telling my experience, not giving advice.
