Modern steel belted radials on '37 wide five wheels

[farmertom]

after reading thread for wide five rims and dyna beads,need input on anybody running modern steel belted radials on wide fives. is it safe to,will they walk off rim in turns,can you run without tubes? my wide white bias ply do have some age to them tread is still very good and all are just getting dry i think were mounted in 2014 and are in pretty good shape i'm just thinking of making a change.most modern radials in 16" are light truck tires iv'e heard 215 85R 16 or 195 85R 16 will work. thanks for input,Tom.
